Check understanding
- State the principle that matter is neither created nor destroyed during physical or chemical changes
- Describe an investigation weighing materials before and after a change to show mass is conserved
- Explain why dissolved sugar still contributes to the total weight even though it can't be seen
“If your child dissolves sugar in water, can they explain why the total weight of the water and sugar stays the same even though the sugar seems to disappear?”
