Here’s a twist on the classic chemical hand warmers you can buy for you to research and improve.
If you’ve been outdoors when it’s really cold, there’s a good chance you’ve either used these yourself or wished you had. You can experience a variation on the science found inside a commercial warmer with some pretty basic materials. You’ll discover how an everyday chemical reaction like rusting is used to keep your digits toasty. This experimental version of the hand warmer is offered as a test idea and not as a definitive solution. You’re encouraged to share your science fair results online.

A solution is prepared containing a dye. The dye, methylene blue, is colourless in a reduced state. Upon shaking the solution, the dye is oxidized and displays a blue colour. As the solution stands undisturbed, the dye fades to colourless as it is reduced. The cycle may be repeated over and over.
For this project you will be designing your own imaginary ecosystem, including the living and nonliving components. You may work by yourself or with a partner. No more than two people may work together on the project. You may either hand draw your poster or can design it digitally using software of your choice. Posters will be placed on the walls around the science classroom once you have completed and submitted them.
