If your child shook a sports cold pack to activate it and it got cold, or lit a match and it got hot, could they explain what type of reaction is happening in each case and why one gets hot while the other gets cold?

Check understanding
- Defines exothermic and endothermic in terms of energy transfer to and from the surroundings
- Gives two examples of each type from everyday life (e.g. combustion, hand warmers; photosynthesis, cold packs)
- Explains energy changes during changes of state (melting is endothermic, freezing is exothermic)
- Interprets a temperature change in an experiment to classify the reaction type
