Here’s a short but sweet activity from today.
Well, it was short and sweet to create but we played with it for over an hour. If there’s something we can learn than killing time isn’t a bad thing, right?
Today we’re learning about colloids!
What is a colloid you ask? A colloid is a substance microscopically dispersed evenly throughout another substance. We’ve seen and used colloids in our lives but were probably never aware that’s what they were. For instance, science clarified lists these everyday things which are colloids: whipped cream, mayonnaise, milk, butter, gelatin, jelly, muddy water, plaster, colored glass, and paper.
We’ve all heard of those things and now we know what they are! So the next time you’re making a sandwich be sure to ask the kids if they would like some colloid (mayonnaise) on their bread!
In our case, it’s some cornstarch dispersed throughout a bit of water.
It’s like quicksand. The more pressure the more it acts like a solid, less pressure and it acts like a liquid.
