Pacing Guide-A Period Is 50 Minutes Long
Pacing Guide-A “period” is 50 minutes long.
Standard III: Students will understand the processes of rock and fossil formation.Objective 2: Describe the nature of the changes that rocks undergo over long periods of time.
Indicator / Main Ideas/ILOS / Time Needed
a. Diagram and explain the rock cycle. / · The rock cycle diagram shows how rocks change over time through the processes of melting, magma, moving to the surface, sedimentation, igneous rock, cooling and hardening, metamorphic rock, high temperature and pressure, sedimentary rock, compaction and cementation, and weathering and erosion. / · 1-2 periods
b. Describe the role of energy in
the processes that change rock materials over time. / · Energy from wind, water, gravity, avalanche, and ice expansion contribute to changes seen in rocks over time. / · 1 period
c. Use a model to demonstrate how erosion changes the surface of Earth. / · Erosion from wind and water sculpt and change the shape of the Earth’s surface over time breaking rock into smaller and smaller pieces while wearing down mountains and hills into plains. / · 2-3 periods
d. Relate gravity to changes in Earth’s surface. / · Gravity causes all weathered materials to travel in a downward movement. / · 1 period
e.Identify the role of weathering of rocks in soil formation. / · Rocks are broken down into smaller and smaller pieces that finally lead to the formation of sand, soil and eventually clay. / · 2-3 periods
f. Describe and model the processes of fossil formation. / · Fossils can form when an organism is buried quickly, deprived of oxygen, heat and pressure that can destroy it, the minerals in the organism are traded with the minerals in the surrounding soil and mud to preserve the fossil specimen. Fossils can be actual remains or evidence like foot prints or leaf prints left in the substrate. / · 2-3 periods
