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:
- Hand warmers are an exothermic reaction
- ice packs are an endothermic reaction
- exothermic reactions loose heat / energy
- endothermic reactions gain heat/ energy
We will be investigating this further in the next few days.
Homework: Read, highlight and annotate the attached article Dynomite Reading
