Week 9 Contact

This week I finished our book of Ancient Civilizations.  Our last one we talked about was the Ancient Aztecs.

We did a science experiment with some of our halloween candy.  We tested lemon heads, sweettarts, and smarties to see which one had a bigger reaction.

We put a little baking soda into each glass with the candy.
The sweet tarts had the biggest reaction, but the lemonheads fizzed the longest, just not very big.  The smarties didn't do much at all.

Then I wrote down in my science journal what happened.  I think the sweet tarts were the most acidic and thats why it reacted the most.
