This Valentine's investigation has two options:
#1 Investigation of gummy heart in water. Includes weighing, measuring, and calculating density before and after submersion in water. Then calculating the percent change, evaluating data, and writing a conclusion.
#2 Inquiry with gummy hearts, gummy rings or other Valentine candy if students have already conducted the gummy bear and water experiment. Same science skills practiced in option #1.
Conducted over 2 days but may not take entire class periods.
