Grade 7 chemical-change work focuses on new substances rather than a change in appearance alone. Students separate physical changes from chemical ones, name reactants and products, and use conservation of mass: atoms rearrange and are not destroyed. Balancing a simple equation is a counting check that the same atoms appear on both sides.

What you practice

These are the Grade 7 Chemical Reactions skills this quiz is built around.

Distinguish a chemical change from a physical change using evidence such as a new substance, gas, or precipitate.
Identify reactants and products and apply conservation of mass to a closed-system measurement.
Count atoms to tell whether a simple equation is balanced.

A useful tip

Color change by itself is limited evidence of a chemical reaction. Look for a new substance, an energy change, a precipitate, or a gas that is not simply boiling water.
