So … what to do with ALL that Halloween candy? I definitely don’t want us eating all of it … therefore, in the name of science we will sacrifice some!
This worked especially well because Henry’s awesome kindergarten teacher (Mrs. Walch) sends home tons of great “homework” activities, one of them being the “Scientist of the Week bag”. This bag contains a labcoat, safety goggles, a book of science experiments (“Apples, Bubbles, and Crystals: Your Science ABCs” by Andrea Bennett & James H. Kessler), and a note explaining the assignment. Kids and parents are allowed to use any appropriate science experiment, not just the ones in the book. And, great timing, this week Henry got to bring the bag home and I saw the link to Candy Experiments … hence a wonderful morning of trying out different candy experiments to find the one to bring to class. (it did take some convincing Henry that using some of his candy for this, instead of eating it … but once I did we had a great time together!)
A simple experiment to test whether or not candy has acid in it. As recommended we used sour candies (sour Skittles to be exact), water, and baking soda. If the candy has acid, the mixture will bubble/fizz when the baking soda is added.
Sink or Float?
We tested whether or not candy would sink or float to discover that all but 3 Musketeers and Whoppers sink. It was great to watch Henry think about why this would be so … he thought about how bubbles float because they are filled with air … sooo, the candy that floats must have more air in them! LOVE IT.
Using M&Ms and warm water we dissolved the candy and watched the m’s float to the top (because the edible ink used does not dissolve in water). This ended up being our favorite by far … and Henry will be demonstrating this experiment to his kindergarten class tomorrow!
