Grade Level: 7th to 9th; Type: Chemistry
Objective:
This experiment provides a graphic illustration of the chemical reaction that transpires when you activate a hand warmer.Research Questions:
- What is in hand warmers?
- How do hand warmers work?
- Why does the “hot ice” form in thie experiment?
Materials:
- Five Reusable Hand Warmers
- Scissors
- Plate
- Bottle
Experimental Procedure
- Activate one of the hand warmers.
- When it turns white and stops giving off heat, cut it open and remove a single crystal.
- Place the crystal on a plate.
