The idea has been on my mind for quite some time.  The teacherspayteachers challenge as well as a little extra time over this summer break was all I needed to get the idea from my head and into a unit.
For this challenge, we had to switch products with another challenger to give and receive feedback.  I traded with my new friend Kim, she had some great suggestions for my product and I enjoying getting a taste of her work as well.  She has some amazing science experiments over at http://kimberlyscottscience.blogspot.com/2015/07/create-your-masterpiece-investigating.html#comment-form
