Students in Mr. Husson's 5th grade science and math class watched the episode "Needle Drop" where scientists were trying to determine which product was the best to prevent the needles from falling off of a Christmas tree. Students first made their hypothesis and then watched the experiment. The seven products were:
Lemon Lime Soda
Santa's Little Helper
Results (Needles dropped in Cubic Centimeters):
300 Lemon Lime Soda
350 Headache Medicine
145 Santa's Little Helper (Medicine)
175 Urethane (Floor wax)
We discussed the experiment and the results. Students agreed that even though the Hairspray was the one that would make the least amount of needles fall off, it would pose a fire hazard. The control in the experiment received pure water and we decided that this would be the be product to use on a Christmas tree.
Students then took these results and worked collaboratively with a partner to graph the results.
They first discussed which would make a better graph, bar or pie, and then made several different graphs using an online graphing website.
