DAY 1:

1. (Use eggs to demonstrate what happens to us when we eat certain foods experiment)

Materials:-4 boiled eggs -1 raw egg-coke, pepsi, or root beer-coffee-vinegar-toothbrush and toothpaste

Procedure:1. Each person or group will receive 4 boiled eggs and 1 raw egg. 2. Take 2 boiled eggs and put them in a small clear cup and cover them with the

soda.3. Cover the other two boiled eggs with coffee in a cup4. Cover the raw egg in vinegar in a cup5. Let eggs sit in these drinks during the day and overnight6. Discuss what the drinks and vinegar might do to the eggs7. Use toothbrushes and toothpaste to clean the eggs off the following day

Objective: The eggs in the soda take on a yellow brown colored stain and the eggs in the coffee were not quite as brown but still had a nice deep yellow stain. Talk about how soft drinks and coffee affected the egg shell and how they can affect our teeth. The raw egg in the vinegar became soft, almost transparent, squishy (like a bouncy ball,) and larger than the rest.

Lessons Learned: -Coffee and soft drinks stained egg shells and they will also stain our teeth.-brushing with toothpaste can help remove stains from eggshells (teeth.)-Soda should not be consumed on the regular.-Taking care of our teeth is important so they don’t get soft and mushy with cavities.-Coffee and soda make your teeth turn yellow.-If we do not brush our teeth the pieces of food with stay in our mouths, mix with bacteria, and make plaque. The plaque will build up on teeth and eat away at them like the vinegar ate the egg shell (Cavities.)

2. (Make a Balloon Rocket)Materials:-1 balloon (“airship” balloons work best)-1 long piece of kite string (about 10-15 feet long)-1 plastic straw

Procedure:1. Tie one end of the string to a chair, door knob, or other support

2. Put the other end of the string through the straw.3. Pull the string tight and tie it to another support in the room.4. Blow up the balloon (but don’t tie it.) Pinch the end of the balloon and tape the

balloon to the straw. Now you are ready to launch!5. Let go and watch the rocket fly

Questions to answer:1. Does the shape of the balloon affect how far (or fast) the rocket travels?2. Does the length of the straw affect how far (or fast) the rocket travels?3. Does the type of string affect how far (or fast) the rocket travels? (try fishing line,

nylon string, string, etc.)4. Does the angle of the string affect how far (or fast) the rocket travels?

Lesson learned: As the air rushes out of the balloon, it creates a forward motion called thrust. Thrust is a pushing force created by energy. In the balloon experiment, our thrust comes from the energy of the balloon forcing the air out. Different sizes and shapes of the balloon create more or less thrust. In a real rocket, thrust is created by the force of burning rocket fuel as it blasts from the rockets engine and as the engines blast down, the rocket goes up!

3. (Make your own slime)Materials:-1/4 cup of water-1/4 cup of white craft glue (Elmers glue)-1/4 cup of liquid starch (used for clothes)-food coloring (optional)-mixing bowl-mixing spoon

Procedure:1. Pour all of the glue into the mixing bowl.2. Pour all of the water into the mixing bowl with the glue3. Stir the glue and water together.4. Add your food color now-about 6 drops should be enough.5. Now add the liquid starch and stir it in6. It should slime by now! As you play with it, it will become stretchier and easier to

hold.

Questions to answer:1. Does changing the amount of water or glue change the feel of the slime?2. Do different glues make better slime?3. How does changing the amount of each ingredient change the slime turns out?4. What happens to slime if it is stored out of a bag compared to in a bag?

Lesson learned:

The glue is a liquid polymer. This means that the tiny molecules in the glue are in strands like a chain. When you add the liquid starch, the strands of the polymer glue hold together, giving it its slimy feel. The starch acts a cross-linker that link all the polymer strands together.

4. (Make your own rock candy)Materials:-A wooden skewer (you can also use a clean wooden chopstick)-A clothespin-1 cup of water-2-3 cups of sugar-A tall narrow glass or jar

Procedure:1. Clip the wooden skewer into the clothespin so that it hangs down inside the glass

and is about 1 inch (2.5 cm) from the bottom of the glass. (as shown)2. Remove the skewer and clothespin and put them aside for now. 3. Get a helpful adult!4. Pour the water into a pan and bring it to boil.5. Pour about 1/4 cup of sugar into the boiling water, stirring until it dissolves. 6. Keep adding more and more sugar, each time stirring it until it dissolves, until no

more will dissolve. This will take time and patience and it will take longer for the sugar to dissolve each time.Be sure you don't give up too soon. Once no more sugar will dissolve, remove it from heat and allow it to cool for at least 20 minutes.

7. NOTE: While it is cooling, some peole like to dip half of the skewer in the sugar solution and then roll it in some sugar to help jump start the crystal growth. If you do this, be sure to let the skewer cool completely so that sugar crystals do not fall off when you place it back in the glass.

8. Have your friendly ADULT carefully pour the sugar solution into the jar almost to the top. Then submerge the skewer back into the glass making sure that it is hanging straight down the middle without touching the sides.

9. Allow the jar to fully cool and put it someplace where it will not be disturbed.10. Now just wait. The sugar crystals will grow over the next 3-7 days.

Lesson Learned:When you mixed the water and sugar you made a SUPER SATURATED SOLUTION. This means that the water could only hold the sugar if both were very hot. As the water cools the sugar "comes out" of the solution back into sugar crystals on your skewer. The skewer (and sometines the glass itself) act as a "seed" that the sugar crystals start to grow on.

5. Does weather really effect mood? (research experiment)Materials:-Weather forecast-Approximately 25 test subjects

-Computer-Printer-Notebook for analyzing results

Procedure:1. Create a survey to give your test subjects that analyzes their current mood.

Example questions could include: Rate your current level of stress on a scale of 1 to 10. How many fights/disagreements have you had today? How many times have you honked your horn while driving in your car today? On a scale of 1 to 10, how satisfied are you with your life? How many good things have happened to you today? On a scale of 1 to 10, rate your current energy level.

2. Wait for a sunny day and ask many test subjects to take your survey. Give the survey at the end of the day to ensure that test subjects have been exposed to the weather long enough for it to have an effect. Include males and females in many different age groups.

3. Ask the same test subjects to repeat the survey at the end of an overcast, rainy day.

4. Analyze the surveys taken by each test subject. Do you observe any patterns in your test subjects’ response to each survey? Do responses differ dramatically between the two days? Are there certain groups of people that seem to be more influenced by the weather?

Objective:

This experiment will evaluate if weather can impact the way people feel.

Questions:

1. Does weather have any effect of mood?2. Are people more likely to be dissatisfied or melancholy on a rainy, overcast day?3. Are people more likely to be happy on a sunny day?4. Is one gender or age group more likely to be influenced by the weather?

It has long been believed that weather has influence over people’s mood and behavior. In this experiment, the emotional disposition of many test subjects will be evaluated on rainy and sunny days to find out if weather can really impact the way people feel.

6. (Fantastic Foamy Mountain)

Materials:

-A clean 16 ounce plastic soda bottle

-1/2 cup 20-volume hydrogen peroxide liquid (20-volume is a 6% solution, ask an adult to get this from a beauty supply store or hair salon)

-1 tablespoon (one packet) of dry yeast

-3 tablespoons of warm water

-food coloring

-small cup

-safety goggles

Procedure:

1. Hydrogen peroxide can irritate skin and eyes, so put on those safety goggles and ask an adult to carefully pour the hydrogen peroxide into the bottle.

2. Add 8 drops of your favorite food coloring into the bottle.

3. Add about 1 tablespoon of liquid dish soap into the bottle and swish the bottle around a bit to mix it.

4. In a separate small cup, combine the warm water and the yeast together and mix for about 30 seconds.

5. Now the adventure starts! Pour the yeast water mixture into the bottle (a funnel helps here) and watch the foaminess begin!

Objective:

Foam is awesome! The foam you made is special because each tiny foam bubble is filled with oxygen. The yeast acted as a catalyst (a helper) to remove the oxygen from the hydrogen peroxide. Since it did this very fast, it created lots and lots of bubbles. Did you notice the bottle got warm. Your experiment created a reaction called an Exothermic Reaction - that means it not only created foam, it created heat! The foam produced is just water, soap, and oxygen so you can clean it up with a sponge and pour any extra liquid left in the bottle down the drain.

This experiment is sometimes called "Elephant's Toothpaste" because it looks like toothpaste coming out of a tube, but don't get the foam in your mouth!

7. (Exploring rock densities with popcorn)

Materials:

-1/4c unpopped popcorn

-1 tablespoon cooking oil

-1 large lidded saucepan

-1 potholder

-1 stove

-1 sample each of obsidian and pumice

-1 magnifying glass

-1 metric ruler

-2 pieces of paper

-1 pencil

-1 glass of water

Procedure:

1. Set one kernel of unpopped popcorn on one of the pieces of paper.2. With adult supervision, pop the remainder of the popcorn according to the

directions on the package (or see directions below); younger kids will need an adult to do this for them.

3. Set a piece of popped popcorn on the paper next to the unpopped kernel.4. Put the obsidian sample on the piece of paper under the unpopped popcorn.5. Put the pumice sample on the piece of paper under the popped popcorn.6. Hold the unpopped kernel of popcorn in your hand and look at it. Then use the

magnifying glass to look at it more closely. Draw a picture of it on the second piece of paper.

7. Under your drawing of the unpopped kernel, write down your observations about it: what color is it? What’s the texture like (smooth or rough, shiny or dull)? Write down any other observations you make.

8. Measure the unpopped kernel, both length and width, and write down the measurements to the nearest millimeter.

9. Put the kernel in the glass of water and see if it floats or sinks. Write this down as well.

10. Repeat steps 6 through 9 with the popped popcorn kernel, the obsidian, and the pumice.

11. Season the rest of the popped popcorn to taste and enjoy it while you think about the research question!

12. Put the oil in the pan and put it on a burner set to medium-high.13. Put three kernels of unpopped popcorn in the oil and cover the pan tightly with

the lid.14. Wait and listen until all three kernels have popped.15. As soon as the third kernel has popped, put the rest of the popcorn in the pan and

close the lid again.16. Using the potholder to insulate the handle, shake and jiggle the closed pan on the

burner, moving it constantly.17. Keep doing this without stopping while the popcorn pops.18. When nearly all of the popcorn is popped, there will be two or three seconds

between popping noises. As soon as that happens, remove the popcorn from the burner, take off the lid, and set the pan somewhere safe to cool. Note: you can use microwave popcorn for this project, but anything the manufacturer adds to the popcorn (salt, oil, etc.) will affect your observations of the unpopped popcorn. Plus when you make it yourself you can flavor it any way you like. Try salt, lemon pepper, a dash of garlic powder, and a drizzle of melted butter.

Objective:

Obsidian is basically “unpopped” pumice: obsidian and pumice are igneous rocks that are made out of the same material, but because of the way it’s formed inside the volcano, pumice looks very different and is much less dense than obsidian. In what ways is pumice it different from obsidian? In what ways is it similar to popped popcorn? How does a difference in density affect something?

8. (Overview of egg experiment results)

first activity of the day

DAY 2:

1. (Pop Bottle Derby)

Materials:-cardboard

-1 plastic bottle

-Hot Glue gun

-1 straw (wider than 1/8 inch)

-2 wooden dowels

-4 plastic pop bottle caps

-a racehorse that includes a ramp and goal line

Procedure:

1. Cut a cardboard base for the bottle. The base can be any size or shape you wish.2. Glue the base to the bottle with the hot glue gun.3. Cut the straw into two 3-inch lengths. These will be used as axle holders. Glue the

straws to the bottom of the cardboard. One piece of straw should be in the front and one should be in the back. Both should be centered.

4. Cut the wooden dowels to use as axles. Secure each axle to the racer by running it through the axle holder.

5. Make wheels by securing bottle caps with glue to the end of each axle.

Objective:

1. See how far you can make a racer travel.2. Harness the power of gravity. Make a ramp and experiment with the angle of the

ramps incline. Add objects to the bottle and see if weight makes a difference.3. Try different materials for the ramp itself. Does a smooth or rough ramp make the

car go faster?4. Challenge friends to a pop bottle race! Whose racer will go the fastest or the

farthest? Set up a racecourse with a goal line, and see whose racer gets there first.

2. (Invisible ink with lemon juice)

Materials:

-Half a lemon

-Water

-Spoon

-Bowl

-Cotton bud

-White paper

-Lamp or other light bulb

Procedure:

1. Squeeze some lemon juice into the bowl and add a few drops of water.2. Mix the water and lemon juice with the spoon.3. Dip the cotton bud into the mixture and write a message onto the white paper.4. Wait for the juice to dry so it becomes completely invisible.5. When you are ready to read your secret message or show it to someone else, heat

the paper by holding it close to a light bulb.

Lesson Learned:

Lemon juice is an organic substance that oxidizes and turns brown when heated. Diluting the lemon juice in water makes it very hard to notice when you apply it to the paper, no one will be aware of its presence until it is heated and the secret message is revealed. Other substances which work in the same way includes, orange juice, honey, milk, onion juice, vinegar and wine. Invisible ink can also be made by using chemical reaction or by viewing certain liquids under ultraviolet (UV) light.

3. (Rainbow in a glass-density)

Materials:

-A glass or clear plastic cup

-Water

-Red food coloring

-Runny honey

-Vegetable or sunflower oil

-Washing up liquid

Procedure:

1. Squeeze or spoon some runny honey into the bottom of the glass until it is 2-3 cm deep.

2. Tip the glass slightly and slowly squeeze the same amount of washing up liquid down the inside of the glass (avoid making bubbles).

3. In a jug, add a few drops of red food coloring to a small amount of water.4. Again, tip the glass and very carefully pour the colored water in to the glass.

Make sure you dribble it down the side so that it doesn’t mix with the washing up liquid.

5. Tip the glass and gently pour the same depth of oil down the inside of the glass.6. Stand the glass upright and admire your liquid rainbow.

Lesson Learned:

-The different liquids all have different densities. Density means how much “stuff” there is in something. Not the things weight or size, but how many atoms it has in it. For example, if you had a shoe box full of feathers and another full of stones, which would be heaviest It would be the one full of stones. Although both boxes are the same size, the box full of stones has a lot more “stuff” stuffed into it, whereas the box feathers is mostly air. We say the stones are denser than the feathers. So in our liquid rainbow, honey is the densest layer and sits at the bottom of the glass, then the washing up liquid comes next and floats on top. The honey is also very viscous (thick) which stops it from mixing. The layer o colored water is less dense than the washing up liquid, and finally the oil is the least dense of all and floats on top.

4 (Make your own lava lamp)

Materials:

-1 clean clear plastic soda bottle (16 oz) with cap

-vegetable oil

-food coloring

-an alka-seltzer tablet

-water

Procedure:

1. Add vegetable oil to the soda bottle until its about ¾ full.2. Add about ¼ water to the rest of the bottle.3. Put about 10 drops of your favorite food coloring into the bottle. Make sure your

water color is dark.4. Break 1 or 2 alka seltzer tablets into chunks.5. When ready, start dropping the chunks into the bottle. 6. Once you have used up all the alka seltzer tablets, top off your soda bottle to the

rim with the vegetable oil and screw on the cap. Let the lava lamo settle and then try tipping it back and fourth to see the neat waves that are created when oil and water don’t want to mix.

Lesson learned:

W have learned that oil and water don't mix. Even if you give the bottle a good shaking, you will notice the oil molecules simple go into little bubbles and don't mix with the water. However, the food coloring and water do mix well.Water is more dense or heavier than oil. Therefore when we added the water is sank to the bottom of

the bottle. The oil was lighter than the water so it floated on top.This is the same effect that happens when an oil tanker sinks and creates a slip on the surface of the ocean.When we added the chunks of Alka-Seltzer tablets to the water there was a reaction. The reaction created small bubbles of carbon dioxide gas. The carbon dioxide bubbles attached to the blurbs or strands of colored water and cause them to float to the surface. Once the bubbles popped, the color blurbs sank back to the bottom of the bottle and a new one rose in its place. This created the lava lamp effect. Now grab some buddies and make a bubbling lava lamp.  

5. (How many drops of water can you fit onto a bottle cap?)

Materials:

-two pop bottle caps

-water dropper

-water

-dishwashing detergent

Procedure:

1. Take two dry pop bottle caps and place them flat side up on a counter.2. Fill your water dropper.3. Drip a drop of water on the cap.4. How many drops of water can you fit on the first cap?5. Now put a single drop of liquid of detergent on the other cap. Then wipe the

detergent off.6. How many drops of water can you fit on this second cap?

Lesson learned:

As you dripped drops on the first cap, the drops of water stuck together due to the natural cohesion of water molecules. You could keep adding drops until there was too much water and surface tension was broken. The film of detergent on the second cap makes it harder for drops of water to form in a group. Fewer drops can be added because soap prevents water molecules from joining together and forming surface tension.

6. (Biome in a bottle)

Materials:-1 pop bottle-pebbles-soil-seeds (from grass, trees, flowers, vegetables, fruit, or whatever you can easily find)

-water-a sunny windowsill

Procedure:1. Remove the top part from your Pop Bottle2. Sprinkle 1 inch of pebbles in the bottom of the bottle3. Add 2 inches of potting soil or topsoil from your yard.4. Run your thumbnail across the center of the soil to make a trench. Sprinkle seeds

in the trench, and cover them with soil.5. Water the seeds until you see water collecting in the pebbles.6. Replace the top of the Pop Bottle.7. You’ve now created a biome8. You wont need to water the seeds again because the closed Pop bottle will keep

recycling the water through the process of evaporation, condensation, and precipitation. The growing plants need to remove the top of the bottle as the plants begin to grow.

9. Put your biome near a sunny window. Your plants should start growing in tree-four days.

Lesson Learned:-You can imitate the conditions of the worlds biomes by changing the amount of sunlight and water your plants receive. A rain forest, for instance, is wet and warm, but the plants there don’t get much sunlight. Deserts get a lot of sunlight and a fair amount of rain. Under which conditions do your plants do best?

Experiment (optional)-You can experiment with different types of plants that are ideally suited for certain biomes. Here are some examples. Ex) Tropical Rain forest: bromeliads, ferns, and common houseplants such as ficus and African violets.Desert: cacti, prairie wildflowers and many kinds of grassesDeciduous forest: ferns, wintergreen, violets, winterberry, strawberries, and blackberriesTundra: mosses and lichens

7. (Potato battery)

Materials:-2 potatoes -2 short pieces of heavy copper wire-2 common galvanized nails-3 alligator clip/wire units (alligator clips connected to each other with wire)-1 simple low-voltage LED clock that functions from a 1-to 2-volt button-type battery

Procedure:1. Remove the battery from the battery compartment of the clock.

2. Make a note of which way around the positive (+) and a negative (-) points of the battery went.

3. Number the potatoes as one and two.4. Insert one nail in each potato.5. Insert one short piece of the copper wire into each potato as far away from the nail

as possible.6. Use one alligator clip to connect the copper wire in potato number one to the

positive (+) terminal in the clocks battery compartment.7. Use one alligator clip to connect the nail in potato number two to the negative (-)

terminal in the clock`s battery compartment.8. Use the third alligator clip to connect the nail in potato one with potato two and

set the clock.

Lesson learned:A potato battery is an electrochemical battery, otherwise known as an electrochemical cell. An electrochemical cell is a cell in which chemical energy is converted to electric energy by a spontaneous electron transfer. In the case of the potato, the zinc in the nail reacts with the copper wire. The potato acts as a sort of buffer between the zinc ions and the copper ions. The zinc and copper ions would still react if they touched within the potato but they would only generate heat. Since the potato keeps them apart, the electron transfer has to take place over the copper wires of the circuit, which channels the energy into the clock.

8. Paint eggshells for the crystal geode experiment go to DAY 3, first activity for directions.

DAY 3:

1. (Make Crystal Geodes)Materials:-Alum powder (Make sure you get the right kind of alum powder, potassium aluminum sulfate. Some commercial alum contains potassium, and some doesn’t. Without the potassium, your crystals will not grow. (2 pounds make a dozen crystal eggs)-Eggshells or plastic eggs-Elmers glue-Pintbrush-Something to put your eggs in to dry-A 4-cup bowl to mix the solution in-A spoon or whisk- for the mixing solution-A measuring cup (3/4 cup of alum powder)

Procedure:

1.(DAY 2) Paint the eggshells with a thin layer of glue.2. While the glue is still wet, sprinkle the egg with alum powder3. Let eggs dry overnight

4. Make your alum solution: If you want to use dye, stir it into 2 cups of water (Easter egg dye or food coloring.5. Heat the water to almost boiling6. Pour ¾ cup of alum powder into the water and stir it for longer than you think is necessary. If there are any crystals in the bottom of the bowl, they will draw alum away from your geodes, and the crystals in your geodes wont get as big.7. Now you leave them overnight to see results in the morning.8. You should have big crystals growing outside of the eggshells!

Lesson Learned:

All substances have a preferred crystal shape, depending on the alignment of the atoms or molecules that make it up. Potassium aluminum sulfates crystal shape is isometric. In other words, this alum likes to make octahedrons. Crystals can only grow in their preferred crystal shape if they aren’t squished. If they’re crowded (as yours will most likely be), they grow into whatever space is available.

2. (Make an erupting volcano)

Materials:-Enough clay to build the volcano -A container that 35 mm film comes in or similar size container-Red and yellow food coloring (optional)-Vinegar-Liquid dish soap

Procedure:-Go outside or prepare for clean-up inside.-Put the container into the volcano at the top.-Add two spoonfuls of baking soda.-Add about a spoonful or dish soap.-Add about 5 drops each of the red and yellow food coloring.Now for the eruption:-Add about an ounce of the vinegar into the container and watch your volcano come alive.

Lesson learned:-A volcano is produced over thousands of years as heat and pressure build up. In this experiment, a chemical reaction can create the appearance of a physical volcano eruption. When a solid turns to a liquid we call this melting and when a liquid turns to a solid we call this solidifying. Gases can dissolve in a liquid and they can be released when the pressure is reduced.

3. (Pop rocks and soda science)

Materials:

-Pop rocks candy-Snack sizes of soda-Ruler-String-Funnel-Online stopwatch-2 balloons-Small plastic cup

Myth: If you eat Pop Rocks with soda, then your stomach will explode. Coke is the favorite legend, but others say milk, root beer, pepsi, dr. pepper, or mountain dew.

Question: Measures Carbon dioxide with warm soda: Does the aount of carbon dioxide vary with soda temperature?

Procedure:1. Put funnel into balloon.2. Pour pop rocks package contents into a plastic cup3. students release cap of soda bottle and place balloon onto soda bottle without

pouring balloon contents into soda bottle.4. Exactly 30 seconds after cap release, pour balloon contents into soda bottle and

wait for balloon to expand.5. When balloon stops expanding, measure circumference of balloon with string.6. Students use cm side of ruler, to measure string circumference in cm.7. Record in student workbook under experiment 1.

Procedure 2: Experiment1. Each student group keeps materials as in experiment 1 and receives:-1 through 5 pop rocks candy packets-1 cold snack size soda-Follow experiment 1 procedure-Record in student workbook under experiment 2

Objective:

States of matter (solid, liquid, gas) depend on molecular motion. In solids the atoms are closely locked in position and can only vibrate; in liquids the atoms and molecules are more loosely connected and can collide with and move past one another, and in gases and atoms and molecules are free to move independently, colliding frequently.

4. (Make colored flowers)

Materials:-water-scissors-food coloring

-plastic cup-flower, white carnation or celery stalk with leaves

Procedure:1. Fill up a plastic cup with water.2. Add a few drops of food coloring to the water.3. Cut the end off the flower stem or celery stalk.4. Put the flower stem or celery stalk in the water.5. Over the next 6-12 hours the food coloring will be drawn up the stem along tiny

tubes which are called vessels and the petals of the flower will start to change in color

6. Put aside and check the following day or two.

5. Make your own solar ovenMaterials:

• Cardboard pizza box• Pencil• Ruler• Box cutter or scissors• Aluminum foil• Clear type of tape• Black construction paper• Plastic wrap or large, transparent plastic bag• Newspapers• Oven mitt• Dish or pie plate• Cooking Ingredients, like those for some mores  or nachos Optional: a thermometer that goes up to 250 degrees F.  

Procedure

1. Clean any stray bits of cheese, sauce or crumbs out of your pizza box.2. Using the ruler and pencil, draw a square one inch in from the edges of the top of

the box .3. Use the box cutter or knife to cut out three of the four sides of the square.4. Make a crease along the uncut side of the square to create a flap that stands up.5. Cut a piece of aluminum foil large enough to cover the inner side of the cardboard

flap.6. Wrap the foil tightly, and secure with tape.  What purpose does the foil serve?7. Line the bottom of the pizza box with black construction paper.  What purpose

does the black paper serve?  Would white paper work as well? Why or why not?

8. Cut two pieces of plastic wrap that are the same size as the top of the pizza box.9. Use tape to secure the plastic wrap to the inside edges of the square window you

cut into the box. You are creating an airtight window.  Why do you want to make your oven airtight?

10. Roll up some newspaper pages into tubes to stuff into the sides of the box.  Make sure you are still able to close the lid of the pizza box.  Remember—what purpose does the newspaper serve?

11. Now it is time to cook something! The best time to use your oven is between 11 AM and 2 PM. Make sure to set the food on a dish so you don’t mess up the interior of your oven.

12. One food option is a solar s’more. Place one or two marshmallows on top of a graham cracker.  Put two to three squares of chocolate on top of the marshmallow.  Wait until it’s done cooking to top it with the second graham cracker. 

6. Turn egg into a rubber ballMaterials:-Hard boiled egg-Vinegar-Small Jar with a lid

Procedure:1. Let your hard boiled egg come to room temperate.2. Place it in the jar and pour the vinegar until the egg is submerged.3. Put the lid on the jar and wait five days.4. Gently rinse the egg with warm water to wash away the shell.

Lesson learned: -The acid in the vinegar eats away at the calcium in the egg shell, creating a rubbery egg.

7. Tornado in a bottleMaterials: -Two 2 liter bottles for each participant or team-tube connector-water-optional glitter-beads-small plastic animals-trees, houses, etc.

Procedure:1. Fill one bottle 2/3 full of water. Screw on the tube connector to the bottle of water

and then screw an empty bottle on top.2. Flip over the bottles and again observe how the water moves from one bottle to

another.

3. Then swirl the bottle with water in it and watch as the tornado is created.4. Add some of the items and create your own tornado.

Lesson Learned:-When swirling the water it causes the liquids to travel in a spiral. As the water swirls in the experiment above it moves the houses, beads, glitter, etc. The items will moe at different speeds depending on where they are in the vortex.
