Reflection Questions:

1. How many heartbeats did you think you would have in one year?
2. Explain what "extrapolating" means to younger children.
3. What are some other things you can extrapolate?  Give some examples.

1. I thought I would have around 45 million heartbeats in one year.
2. Extrapolating means to make something bigger or longer. Like with this experiment I extrapolating my heart rate by multiplying my heart rate in 20 seconds by 3.
3. You can extrapolate a sentence if it has five words, you can extrapolate it by adding a because, because then you explain more (haha).

1. Yes, it definetly does. At the 15 minute mark, the cup with enzyme had a little bit of the enzyme-Jell-O mixture at the bottom of the cup. The cup without the enzymes, on the other hand, had nothing at the bottom.
2.  We didn't change the temperature of the gelatin, so I don't really know if it did or not.
3. Yes, it does, because when you chew something your saliva helps to start breaking down your food. And, of course, chewing helps because it breaks it down into little pieces, so it's easier to digest.
