3.You need to use oil on the bottle.

4.Burning paper made the egg get into the bottle. 5.You had to use a raw egg.

Did you like it?You had to use a raw egg.

Stick a picture of your process or result!

3.Make it SnowTopic:Textures and snow formation

Objective:The student will observe the interior of everyday objects, their textu-res and how they work.

Vocabulary:Diapers, textures, remove, mixture

Material:•Water•Diapers•Container

Development:1.Open the diaper and remove all the cotton that is inside.

3.All the dust that you have removed from the diaper must be gatheredin the container.

2.Rub the cotton with both hands, a small white powder must fall asit crumbles.

4.Once it is in the container, shake it so that the extra cotton stays on top, and then remove it. It seems to be few powders to create a little snow, but it will be enough.

6.Wait a few seconds, watch how the mixture turns into snow.

5.When you have all the substance separated from the cotton, add a little water in the container

7.You can turn the container and check that the snow, even, stays inside it, that is to say that it has a lot of consistency.

Hello! For this Science experiment we had to use different material, and we used it in different steps.

Let´s go back through them… First we had to hang the (1)____________________ around one of the cups with an (2)____________________ to keep it lighted.

After that we had to do the same with the (3)____________________ and the other glass.

Then we filled the glasses with the same amount of (4)____________________.

Finally we measured the temperature of the water in the glasses with the (5)____________________ and let two hours pass by placing the (6)____________________ in the sun and re-measuring the water temperature in each one

water thermometer elastic band

black paper white paper glasses

1. Take the plastic bottle and with the scissors cut the bottle about 10 cm be-low the top, starting from the lid.

2. Stick some tape on the outside of the bottle, starting from the top to the bot-tom. Make sure that the tape sticks as straight as possible.

5. Water clockTopic:Time and watch types

Objective:The student will know another type of clock and its capacity to me-asure time.

Vocabulary:measure, type, flows, procedure

Material:•A plastic bottle of 1 L capacity•A paper or plastic cup (like birthday cups)•A watch with a second hand•A ruler•A pencil•Tape•Scissors

Development:

3. Make a small hole in the bottom of the plastic cup, and place it in the bo-ttle, so that it is supported by it.

5. While the water falls, mark the tape after 30 seconds at the water level of the bottle. Repeat the procedure for 5 minutes (always every 30 seconds).

4. Looking at your watch, put water in the cup so that it is always half full, so that the water flows continuously.

6. Stick another piece of tape next to the previous one and repeat the expe-riment, but this time marking the water level every minute
