This science and math lesson uses coated candy and water to create a rainbow on a plate. It takes a popular internet activity and modifies it for the classroom. It's extended by having students hypothesize if other temperatures of water will work and if different colors of the candies run faster than others. It also meets the math SOLs because students can calculate the cost of the experiment and/or create graphs of the results of the experiments.  You could extend this activity into art or English writing by having students draw their rainbows or write about what they saw happening on the plate as a report writing. You could have them take it a step further and do a creative writing about what they think is at the other end of the rainbow. 

Your students will use Kitchen Chemistry to make a tasty treat as they learn about input and output devices and phases of matter! 

What do you think will happen to Peppermint Puffs that are put in warm water, cold water, oil, and vinegar?  Will they dissolve?  In which substance will they dissolve the fastest?  In this experiment, your students will find out!  Students will also record their data and use technology (a spreadsheet on their Chrome book) to analyze, graph and discuss their learning.

What materials dissolve in water?  How does water temperature affect this?  Your students will work in groups using a thermometer and timer to discover if salt, sugar, sand, and flour will dissolve best in hot or cold water.  Further, your class will learn to record and submit data on a Google form and create graphs.  This will allow you to have great class discussions to draw conclusions about the effect temperature has on dissolving matter.
