5A/B Natural Science - Solid or Liquid? Experiment

Hello, fifth grade!

Here is a science experiment you can do AT HOME. (with the permission of your parents)

We know there are three states of matter: Solid, Liquid, and Gas.

In this video, they are talking about a strange type of substance that acts like both a liquid AND a solid. It is called "oobleck" because it comes from a Dr. Seuss book!


As you can see, you can move your fingers through it like liquid, but you can pick it up and mold it with your hands like a solid!

It has high surface tension, so you can see how the hand does not make the water splash (salpicar) and it is strong like a solid.

You can make "oobleck" by mixing one part water to two parts corn starch (maicena). So, you can use a half cup of water and one cup of corn starch. You can also use food colouring if you wish.

NOTE: Ask your parents before doing this experiment!

Have fun!
