Our fun activity today was a density glass. Here it is in progress. The first three or four liquids separated very well, but then we added one that didn't separate very well. We had caramel, syrup, milk, dish soap, water, rubbing alcohol, and vegetable oil.
Then we put some items in too...a bolt, rice, ping pong ball. Isaac never quite grasped the concept of density, but had fun putting things in the glass.
I tried to get Isaac to drink the black water, but he wouldn't.
I put the glass in the fridge to see if things would separate more over time...and they did. It's a bit harder to see in the picture, but the strips are obvious, although not well defined.
