week 13

 This week in science we did a really cool experiment that goes with what we have been doing in prior weeks. The experiment that we did this week was seeing how different factors can affect a single thing or group of things. 

We first learned about how the thing we were testing, which was M&M's, are made up of different chemical compounds. For example, the candy shell on the outside of the chocolate is different from the chocolate in the inside. We also learned how to make predictions and claims to back up the evidence of our experiment. Prior to the experiment, we tested out how the candies react to regular water. We recorded how these two react with one another, which was that the candy shell would dissolve when in the water, then we set up our next experiment. Our next experiment consisted of testing out if the M&M would dissolve their candy outer shell faster with regular water or sugar water. 

Here are some photos from our experiment:

Our claim for our experiment

After the experiment was done, we came to the conclusion that when the candies are in the sugar water, they dissolve slower because there is already sugar in the water which allows little to no room for the sugar from the candy to dissolve. Whereas in the water there is more room for the candies to dissolve. 

After this class and doing these experiments, I do not have any questions in regard to the content. I had a lot of fun in class this week learning about all these different things and it was fun having Mike in our class teaching!
