Term 2 Goal Reflection

Here are my reflections on my term 2 learning goals.

why did the popcorn dance?

Have you ever wondered how t make the popcorn dance? Well me and some people from my class have done an experiment. There were allot of steps but it was really fun.

Firstly you fill a transparent glass three quarters of the way up.
Then you put two drops of food colouring in and stir.
Next you put in vinegar and lastly the kernels in. To finish of, you put in baking soda and away they go.

The popcorn kernels started jumping up and down it looked liked they were dancing. They started to go up and down.

The kernels went up and down because when they were at the bottom they got surrounded by bubbles and floated up. When they were above the surface the bubbles popped and the kernels went down. This is repeated until the baking soda ran out.

With all these ingredients there is a way to make popcorn dance. You can see it for yourself too
