Conservation of Mass
Measure and provide evidence that the total weight of matter is conserved regardless of the type of change (heating, cooling, or mixing)
Typical age: 10–11 years
“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?”

Needs first
- Irreversible ChangesREQUIRED
Must understand irreversible changes before proving mass is conserved in all types of change
- Reversible ChangesREQUIRED
Must understand reversible changes before investigating conservation of mass during changes
- Matter Is Made of Particles
Particle model supports understanding why mass is conserved (particles aren't destroyed)
