The aim of this activity is for students to be able to recognise chemical changes. Reaction experiments involving heat and chemical mixtures are used to help students distinguish between physical and chemical changes as well as endothermic and exothermic concepts.
This item teaches:
- about the detectable features of a chemical reaction
- the definition of an endothermic reaction
- about the transfer of energy as a result of chemical reactions
- the definition of an exothermic reaction
