Models and Systems
The
Models and Systems unit guides the student to understand
that models are used to represent objects in the real
world and identify limitations that models have.
Students will compare and contrast characteristics of
the moon and the earth and review physical
characteristics of the sun. The student will identify
the sequence of the phases of the moon and identify the
role the tilt of the Earth plays in the seasons. The
student will describe some interactions that occur
within this simple system. Basic resources include:
McGraw-Hill Science textbook, FOSS Investigations,
Digital Curriculum Press titles (downloadable videos
available from the internet), CFB Smart Plus
lessons/questions (password: smart), and web-based
resources.
Critical Questions:
- What causes the seasons?
- What causes night and day to occur?
- What causes us to see different shapes of the moon
each night?
- What interactions occur in this simple system?
- What would happen to this system if a part was
missing or quit working?
- What is the difference between a system and a
cycle?
- What limitations do models of the solar system
have?
Suggested Time Frame: 4 Weeks
