Lesson Plan: The Relationship Between Science and Technology
- Lesson Plan
- Standards
Overview
Students will learn how technology can help scientists solve a problem. One of the challenges scientists face with any spacecraft is attitude control. Students will be introduced to the problem of attitude control in space and two different ways scientists address it.
Objectives
Students will
- Discuss the technology(ies) that powers satellites and enable(s) them to move through space
- Be introduced to the concept of “attitude control” and the role technology has in the design of spacecrafts
- Engage in an angular momentum experiment
Assessment Strategies
Facilitate student discussion to recommend the best way that scientists can get the Swift satellite to change directions. See Teachers Notes PDF Document for elaboration.
Grade Level: 5-8
Suggested Time
30 minutes
Multimedia Resources
Gamma-ray Burst Theories QuickTime Video
Materials
- A swivel chair
- A gyroscope
- A bicycle wheel with handles (see Teachers Notes PDF Document for an example of this, p. 3)
Note: Most physics teachers at your high school will have this bicycle wheel with handles.
Note: YouTube often contains videos on angular momentum as an alternative exercise.
Procedures
See Teachers Notes PDF Document for elaboration.
Part 1: Ask students how satellites change orientation in space. After discussing various ways it can be done, show Video 4:

[Time – 4:11]. Then, ask them questions regarding role of technology and movements of Swift satellite.Part 2: Explain the concept of attitude. Then, by using a swivel chair, illustrate the problem that the scientists face with getting a satellite to change its pointing direction.
Part 3: See Teachers Notes PDF Document for further elaboration. First, ask students what might solve the problem. Explain using thrusters as one possible solution and the disadvantages of using thrusters. Next, explain the second possible solution that momentum wheels can be used to change the direction. Facilitate two students demonstrate angular momentum: one student is rotating the bicycle wheel, while the other student is holding the wheel on a swivel chair. Further, explain the twisting motion, torque.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain.
