8th Grade Science Curriculum
Motion and Forces
1. Forces between objects act when the objects are in
direct contact or when they are touching.
2. Forces have magnitude and direction.
3. There are different types of potential energy.
Physical Earth
1. The composition and properties of Earth’s interior are
identified by the behavior of seismic waves.
2. Earth’s crust consists of major and minor tectonic plates
that move relative to each other.
3. A combination of constructive and destructive
geological processes formed Earth’s surface.
4. Evidence of the dynamic changes of Earth’s surface
through time is found in the geologic record.
Species and Reproduction
1. Diversity of species occurs through gradual
processes over many generations. Fossil records provide
evidence that changes have occurred in number and
types of species.
2. Reproduction is necessary for the continuation
of every species.
3. The characteristics of an organism are a result
of inherited traits received from parent(s).
