  1. Endothermic and Exothermic Reactions By: Corin Burke, Sydney Dunn, Kali Pierre, and Lexy Freeman

  2. Sodium Chloride Experiment Water Temp. Before: 76 degrees F. Water Temp. After: 134 degrees F.

  3. Baking Soda and Vinegar Experiment Water temp. before: 74 degrees F Water temp. after: 66 degrees F

  4. How is iron affected when exposed to oxygen? Oxygen causes iron oxide, which produces rust and released thermal energy.

  5. Conclusion • Hand Warmer- Exothermic, Chemical to Heat, Released • Sodium Chloride- Exothermic, Chemical to Heat, Released • Baking Soda and Vinegar- Endothermic, Chemical to Heat, Absorbed
