Gretta showed me these test tube experiment kits she picked up at Hobby Lobby and gave us two test tubes to try out. Thanks again! Cody wanted to do one of the experiments today and he was very precise deciding which one. Hey...eeny, meeny, miny, moe is strategic:) We ended up doing the Garbled Marbles experiment, which was lots of fun for the Code-Man.
Cody poured the bag of tiny marbles into the container before we sorted them.
Soon, we could see that the marbles were absorbing the water and growing. The bigger they get, the squishier they are:) Huh...Maybe I'm a polymer! LOL!
Cody placed two of each colored marble back into the test tube so he could observe the changes through the clear plastic.
There are seven plastic cups sitting on my kitchen table and Cody has shoved his hands in every cup...several times each...feeling the squishy, expanding marbles. He can't wait to see how they look in the morning!
