March Mad Scientist Week: Kitchen Science

Yesterday we did several kitchen science experiments:

1. Yeast: we activated yeast using sugar and warm water in an empty water bottle, put a balloon around the rim of the bottle, and then watched as it inflated the balloon.

2. Lemon Juice Art: we colored with lemon juice and q-tips, let it dry and then baked at 350 for 5 minutes. The heat browns the juice and makes a picture appear. Make sure you saturate your q-tip often.

3. Cornstach and Water Goop: by mixing 1 part water to 2 parts cornstarch, we made a substance that was a liquid when you held it and a solid when you moved it around.

4. Vinegar and Baking Soda volcano: We colored our white vinegar with a little food coloring to make it red, then poured it into our container of baking soda to make our volcanic eruption.
