STEM Challenge

Last week we finished our monthly STEM challenge. My students LOVE these. They are from Smart Chick Teaching Resources on TPT.
 
This months challenge was to choose the liquid that will dissolve a peep in the fastest amount of time. We chose 5 liquids. We used water, hydrogen peroxide, Sprite, apple juice, and canola oil. Most of my students thought that hydrogen peroxide would dissolve a peep in the shortest time. 
We let them sit for 6 days and made daily observations during that time. We discovered that water dissolved the peep the fastest in the shortest amount of time. Here are pictures of our results. The first picture is the peep that was in water.


We actually had some mold growing the apple juice container. 

These monthly challenges have been so fun to do as part of our morning routine once a month!
