Science
Grade 7 · US Curriculum Standards
Seventh grade science deepens both life and physical science. Students study chemical reactions and evidence that a new substance has formed, conservation of mass, synthetic materials, and the relationship between kinetic energy, mass and speed.
Life science covers photosynthesis and respiration as complementary processes, how matter and energy move through organisms, reproduction and genetics, and the role of natural selection. Earth science covers plate tectonics, the rock cycle and geologic time.
