In class we practiced asking scientific questions about what we saw with hand warmers and ice packs and how they worked.

Take Aways from Class:

  1. Hand warmers are an exothermic reaction
  2. ice packs are an endothermic reaction
  3. exothermic reactions loose heat / energy
  4. endothermic reactions gain heat/ energy


We will be investigating this further in the next few days.
