Unit 6 Rocks
Overview - The rock cycle, which is continual in nature, explains the formation of minerals and rocks. Fossils provide evidence of constant environmental change.
Standards:
Students will investigate the scientific view of how the earth’s surface is formed.
Investigate the contribution of minerals to rock composition.
Classify rocks by their process of formation.
Describe how fossils show evidence of the changing surface and climate of the Earth.
Students will describe various sources of energy and with their uses and conservation.
Identify renewable and nonrenewable resources.
Students will investigate the scientific view of how the earth’s surface is formed.
Compare and contrast the Earth’s crust, mantle, and core including temperature, density,
and composition.
Describe processes that change rocks and the surface of the earth.
Explain the effects of physical processes (plate tectonics, erosion, deposition, volcanic
eruption, gravity) on geological features including oceans (composition, currents, and
tides).
Questions - Students will be asked to answer these questions throughout this unit of study.
#1 How are rocks formed?
#2 How are rocks classified?
#3 How can rocks change from one type to another?
#4 Is the rock cycle really a cycle? Explain your answer.
#5 How are rocks used by 6th graders?
