Grace and Jack made bouncy balls and through this experiment they learned that the balls they made, although they looked and felt like a solid, were actually not! Instead, their bouncy balls were something between a solid and a liquid called viscoelastic! They discovered that their bouncy balls eventually started flattening out when they were not touched.
Here is how Grace and Jack make their bouncy balls:
1) Mix 1/4 cup of white glue with a few drops of food coloring.
2) In a separate glass, dissolve 1 tablespoon of borax in 1/2 cup of warm water. Add 2 tablespoons of this mixture to the glue mixture and mix together. Grace and Jack played with this mixture for awhile before moving on to the next step.
3) Add a few drops of the extra borax mixture to the dough mixture made above and begin rolling it between your hands to form a ball. Continue rolling the ball until it is hard and dry enough so that if dropped, it bounces.
Here are some pictures of Grace and Jack making their bouncy balls...
Grace, Jack, Eve and I all worked together to make this I Spy letter bottle. We filled a bottle with rice that we colored red and placed the uppercase and lowercase letters that we have been working on creating over the past several weeks inside. Eve loves this I Spy bottle. She does a such a great job shaking it to find the hidden letters inside. Great job, Eve!
Grace and Jack love science and conducting science experiments. Yesterday, they mixed a solid (baking soda) and a liquid (vinegar) together inside of a bottle to create carbon dioxide gas. Once the chemical reaction started they quickly placed a balloon over the top of their bottles and magically watched the balloon inflate! Through this experiment, Grace and Jack learned that the carbon dioxide gas they created was heavier than the air in the bottle. The carbon dioxide gas pushed the air upward and into the balloon to inflate it!
