Tasty Science

Ashby & John (O's godfather) sent Olivia the coolest "Tasty Science" kit for Christmas. Originally I had told the kids that we had to wait for a rainy day to open it, but the weather turned cold enough that we couldn't play outside for long - so we got into it yesterday.

EXPERIMENT #1: Fizzing Flavor-ade

First, we had to line up all the supplies on the counter: test tubes, measuring scoops, citric acid, baking soda, sugar and flavorings.

After mixing citric acid and baking soda, Olivia added water to watch it fizz.

Then, we added watermelon and raspberry flavoring (and lots more sugar than it called for!) until it tasted good. Olivia thought hers was tastier than McIver did.

EXPERIMENT #2: The Rise of the Cupcake

This experiment required more hands-on participation from Mom so there aren't any pics of the mixing of ingredients. But, the kids were anxious for 10 minutes to pass to see which cupcakes, side A or side B, would rise.

Olivia's hypothesis: The side with the most ingredients will rise.

McIver's hypothesis: The side with not as many ingredients won't rise.

(Yes, they had the same hypothesis, Mac just took longer to say it!)

Waiting, not so patiently, to see which side will rise.

They were both right - Side B, with the baking soda and vinegar, rose (and tasted better!).
