Demonstrate you understanding of refraction by creating a variety of solutions to examine.
MODEL CURRICULUM (GRADE 8)- Earth and Space Science
TOPIC- Physical Earth
CONTENT STATEMENT- The composition and properties of the Earth’s interior are identified by the behavior of seismic waves. The refraction and reflection of seismic waves as they move through one type of material to another is used to differentiate the layers of Earth’s interior. Earth has an inner and outer core, an upper and lower mantle, and the crust.
GRADE 8 CONCEPTS- It is important to provide the background knowledge regarding how scientists know about the structure and composition of the interior of the Earth (without being able to see it).
