Description

Grade 8 science completes the K–8 sequence with physics, astronomy and the science of heredity. Students measure speed and velocity, analyze balanced and unbalanced forces, apply Newton's laws to collisions and design ways to reduce damage. They study sound waves and how they interact with matter, non-contact forces of magnetism, electricity and gravity, and the Earth–moon–sun system, solar systems, stars and galaxies. In life science they explore Mendel's genetics, DNA, mutations and reproduction, and the evidence for natural selection and common ancestry.
