Late Unit sheets will lose one grade level for each day late. If you do not add up your scores correctly or lie about scores you may receive 1/2 credit on the whole unit. Be honest with yourself. In order to keep your parents informed of your work and what we are doing in class let them see this list of assignments. It must be signed before you turn it in. This can be done any time. This is REQUIRED or I will not accept your work.

Science Benchmark

Earth is a dynamic planet. Processes that change Earth's surface operated in the past much as they do today. Evidence of past surface and climatic changes are indicated in the rock and fossil records. Rocks are composed of minerals. Rocks and minerals cycle through processes that change their form.

Several processes contribute to changing Earth’s surface. Earth’s surface is changed by heat flowing from Earth's hot interior toward the cooler surface and by atmospheric processes. Earth’s surface can change abruptly through volcanoes and earthquakes. Earth’s surface can change gradually through mountain building, weathering, erosion, and deposition. Small changes that repeatedly occur over very long time periods can add up to major changes in Earth’s surface.

Standard III Continued: Students will understand the processes of rock and fossil formation.

Objective 3

Describe how rock and fossil evidence is used to infer Earth’s history.

a. Describe how the deposition of rock materials produces layering of sedimentary rocks over time.

b. Identify the assumptions scientists make to determine relative ages of rock layers.

c. Explain why some sedimentary rock layers may not always appear with youngest rock on top and older rocks below (i.e., folding, faulting).

d. Research how fossils show evidence of the changing surface of the Earth.

e. Propose why more recently deposited rock layers are more likely to contain fossils resembling existing species than older rock layers.

Objective 4

Compare rapid and gradual changes to Earth’s surface.

f. Describe how energy from the Earth's interior causes changes to Earth’s surface (i.e., earthquakes, volcanoes)

g. Describe how earthquakes and volcanoes transfer energy from Earth's interior to the surface (e.g., seismic waves transfer mechanical energy, flowing magma transfers heat and mechanical energy).

h. Model the process of energy buildup and release in earthquakes.

i. Investigate and report possible reasons why the best engineering or ecological practices are not always followed in making decisions about building roads, dams, and other structures.

j. Model how small changes over time add up to major changes to Earth’s surface.
