~Home Science 101~

Here's a peek at our Science Discovery Board.

Experiments completed along with their own vocabulary words. 

And yes, there will be a test (but not for you).

And our word for this lesson?

COLLOID:

a special kind of mixture in which particles of one type of material 

are suspended in another kind of material.

(the straightforward  fourth grade definition)

In other words?

Blue Goo.

COLLOID:

how to keep a fourth grader happy and busy in the name of science

(the mom definition)

Want to make your own colloid?

All you need is:

1 cup cornstarch

1/2 cup water

blue (or other color) food coloring

a medium bowl

someone willing to get their hands dirty in the name of science

1. Put the cornstarch into the bowl.

2. Pour in the water. Add a few drops of food coloring to the mixture.

3. Using your hands squish the cornstarch and water together. It will get messy but keep you mesmerized.

Is it a solid? Is it a liquid? NO- it's a colloid! Now don't you feel smart? ;)

Cheers!
