Week 5:
Land
Weeks 4, 5, and 6
make up a three-week cycle about land (Lithosphere). Currently, you are
in Week B: Teacher As Scholar.
This week, build your own knowledge
of the Lithosphere. Use the resources listed under Readings,
discuss your questions and answers with your teammates, then submit your
individual questions and answers to your Portfolio. Work with your team
to come up with well-supported answers to the essential questions and
submit them to the portfolio for a grade.

Essential
Questions about Land
Work with your teammates to
answer each other's questions and these essential questions:
- How do rocks change?
- Where does soil come from?
- How does soil help plants
grow?
- What happens to plants when
they die?
- How do Earthworms affect
the soil?
Readings
1. Earth at Hand, PPS. 39-47.
2. On your own, read about
the following topics related to the study of land.
- Biomes research
- Research on soil types
- Soil layers and age
- Rock cycle
- Soil reflection and absorption
- Soil absorption and water
run-off
3. The content children are
expected to know is described in the National
Science Education Standards and Project
2061 Benchmarks:
- Chunks of rocks come in
many sizes and shapes, from boulders to grains of sand and even smaller.
- Earth materials include rocks (including
minerals) and soil.
- The Earth, made of rocks
(and minerals), has many shapes.
- Soils have the properties of color and texture,
the capacity to retain water, and the ability to support the growth of
many kinds of plants, including those used for human consumption.
- Rock is composed of different combinations of
minerals. Smaller rocks come from the breakage and weathering of bedrock
and larger rocks. Soil is made partly from weathered rock and partly
from plant remains and also contains many living organisms.
- Most rocks are made of several substances
(minerals), but some rocks are made of one substance (minerals).
- The surface of the Earth
changes. Some changes are due to slow processes such as erosion and
weathering, and some changes are due to rapid processes such as landslides,
volcanic eruptions, and Earthquakes.
- Rocks are found in layers formed over a long
period of time.
- All rocks break apart
and form new rocks (rock cycle).
