Materials: 1l bottle Funnel Vegetable oil Water Food colouring Alka-Seltzer tablet Glitter

Instructions:

Fill a clean bottle ⅓ full with water Add a few drops of food colouring Fill the rest of the bottle with cooking oil Break up an Alka-Seltzer tablet

and add it to the bottle about ½ at a time. Watch! Don’t use yellow colouring as it doesn’t show against the oil Add glitter to make a change.

Materials: Glass jar or vase Moth balls Vinegar Bicarbonate of soda Teaspoon

Instructions: Fill the jar with water Stir in about ⅓ cup of vinegar and 2 teaspoons of bicarbonate of soda - stir carefully and slowly so the mixture doesn’t froth up too much.

Drop a few moth balls into the fizzy liquid.

Bouncing Moth Balls

Be warned: this can go on for several hours! The bubbles are carbon dioxide which is formed when the vinegar and bicarbonate of soda join together. When the moth balls are at the bottom of the jar, they collect bubbles. The bubbles are lighter than water and they lift the moth balls to the surface where the

bubbles escape and the moth balls then sink down again. If the moth balls are too smooth, the bubbles can’t hold on so the trick won’t work. Rub the surface with sand paper to rough it up a bit!

Materials: Plastic bottle with cap or jar with lid Water

Washing up liquid glitter

Instructions:

Fill the plastic bottle with water and add a few drops of washing liquid. Add a pinch of glitter to make your tornado easily visible (optional). Put the cap. Turn the bottle upside down and spin it in a circular motion for a few seconds. Look inside if you can see a tornado

forming in the water. The Science behind the Experiment When you spin the bottle, it creates a vortex that looks like a tornado. The water spins around the center of the vortex due to the force (centripetal force) directing fluid towards the center. Note – You may have to practice it a few times before showing this to your kids

Materials: • Different food colours • Water • Sugar • Glasses (5)

• PATIENCE

Instructions: • Arrange all the glasses on the table and add 3 tbsp of water into the first four glasses. • Now add one tbsp of sugar into the first glass, two tbsp of sugar into the second glass and so on. • Stir well until the sugar dissolves. • Next, add different food colors to each glass. • Pour only 1/4th of the fourth glass into the last glass (glass no. 5) • Now slowly pour the next layer in a way that it doesn’t get mixed with the first layer. • Keep on adding other layers in a glass.

Rainbow in a glass

Adapted from The humarnation

Rainbow is caused by reflection, refraction, and dispersion of light in the water droplets that result in a spectrum of light appearing in the sky. But do you know you can also form a

rainbow at your home? This science activity involves the concept of density to create a beautiful

rainbow in a glass. The Science behind the Experiment The different amounts of sugar you added in the glass create different densities. The denser

solution will sit at the bottom, and the lightest will rest on the top. Practice until you get all the layers resting on the surface.


Materials: • White paper

• Cotton

• Bowl • Lemon juice

• Blow Dryer

Instructions:

• Pour lemon juice in a bowl • Dip the cotton in the juice and write your secret message on the paper.

• As soon as you write the message, you will see juice fading as it seeps into the paper. • Next, use the blow dryer to see your secret message ‘appear’ on the paper.

Invisible Message

Adapted from Stepmamming

Note – If you use real lemon juice, the message will become visible only when the light is thrown on the paper. If you use freshly squeezed lemon juice, the message will turn brown. To make this science experiment more interesting. Repeat the same steps with different fruits available at your home to see how the message clarity differs.


Materials:

• Cornstarch

• Bowl • Spoon for mixing

• Food coloring (optional)

• Take a bowl and add two cups of cornstarch into it. • Add water and a few drops of food coloring.

• Mix the ingredients with hand or with a spoon. • You are ready

This magic mud will have both liquid and solid properties.

Squeeze the mud, and enjoy the shapes. Try to roll a ball in your hand and then let it trickle through your fingers

Try slapping it- solid

Write in it – can you write a letter before it disappears

Let your child experiment with adding more cornflour/ water and see how it effects the properties

Solid or liquid cornflour (magic mud)


Materials: Balloon

Your hair or jumper

Thin paper cut into little frogs or just shapes

Cut up your different types of paper into frog shapes (or anything else you want to make jump)

Blow up your balloon and tie it

Rub in quickly on your hair or jumper

Hold it above your paper frogs and watch them jump

up

Jumping Frogs

Balloons and some other objects like a fluffy

jumper can steal electrons from other

surfaces. The extra electrons give the

balloon a negative charge, which attracts other objects, like the tissue paper we use in

this activity.

A fun way to demonstrate static electricity is by making jumping frogs.

Materials:

3 eggs

3 empty vitamin tablet tubes

3 wine glasses or tumblers

1 cork based place mat

Water

Instructions: 1. Half fill the wine glasses with water and arrange them in a triangle or straight line. 2. Put the place mat on top of the glasses with the shiny side facing down, and the cork side facing upwards.

3. Carefully balance the tubes on top of the place mat, open end up, so each is directly over the center of a wine glass. 4. Place an egg on top of each tube. 5. Now comes the scary bit; give the board a short, hard slap and it will

slide out of the way, letting the eggs fall into the glasses!

Materials: 1 small plastic bottle Vinegar Bicarbonate of soda Balloon Teaspoon Paper funnel

Instructions:

Put 1cm of water into the bottle then add 2 cm of vinegar. Use the funnel to put 2 teaspoons of bicarbonate of soda into the balloon. Place the mouth of the balloon over the bottle, making sure none of the bicarb falls into the bottle.

Lift the end of the balloon and allow all of the bicarb to fall into the bottle in one go. Shake it well and watch the balloon inflate itself! This is a reaction between a base (bicarb) and an acid (vinegar) which

produces a bi-product (carbon dioxide). The gas cannot escape and therefore fills the balloon.
