8th grade science moves from observation to explanation using models and evidence. Students investigate matter and reactions, forces and motion, energy and waves, and Earth's changing crust, while learning to plan fair tests and weigh claims.

Key Topics Covered:

Elements, compounds and mixtures, chemical reactions, Newton's laws, energy transfer, waves, plate tectonics, the rock cycle, investigation design and data analysis.

Parent Tip:

8th grade is when students start using scientific models and evidence on purpose. Strong foundations in matter, forces and energy make high school biology and chemistry easier, and most states test science this year.

Classify matter and tell physical from chemical changes

Show that mass is conserved in chemical reactions

Apply Newton's laws to everyday motion and safety problems

Trace energy transfers and describe how waves carry energy

Explain plate tectonics and the rock cycle with evidence

Plan fair tests and evaluate scientific claims
