📋 Teacher Answer Key
1. reactants
2. a model showing reactants and products
3. the total amount of matter stays the same in a closed system
4. products
5. It shows that the same kinds of atoms are present before and after the reaction even though they are rearranged
6. two substances react and form a new solid
7. rearranged
8. The two models help connect visible evidence, atomic rearrangement, and conservation of matter

Before This Topic

Use these earlier skills when the current lesson feels too fast or assumes knowledge students do not yet control.

Build BackgroundGrade 6
⚛️Matter and Particle Models

Use particle models to explain matter, state changes, simple atomic structure, and how substances can combine or stay as mixtures.

Build BackgroundGrade 7
🧪Chemical Reactions and Conservation

Use particle models and evidence to explain chemical reactions, reactants, products, and why matter is conserved even when substances change.
