Teacher Area-Spin Through Solar System

Picture of Solar System

1995 The Regents of the University of California

Concept:

There are many ways to introduce high-tech into the teaching of science and math in our schools. One way is to develop lesson plans in which students play an active role in collecting necessary information from the Internet and in using this information to do calculations and to make conclusions. Solar System Internet data and images can be used as a basis for such work. In this activity, students will use surface features of Solar System objects to calculate the objects' rotation rates.

Theme:

"Take a Spin Through the Solar System" can be used as a complete unit for astronomy courses, or it can be broken into separate lessons for teaching physics, space or general science, and even math. This material is a good example of how an Internet-based activity can be successfully incorporated into classroom activities in order to increase the quality of science and math education, and also to help students become accustomed to working with computers.

Time:

One day to two weeks

Materials:


Goal:

To determine the rotation rates of the Sun and the planets in our Solar System using the best information available on the Internet.

Objectives:


Directions:

There are two ways of working with this unit. The first one is more traditional. You will:

  1. Introduce new material in class

  2. Explain how the rotation rates of planets can be calculated

  3. Refresh math concepts and formulas, such as: What is ratio? How to measure an arc in a circle? What is angular velocity?

  4. Use one planet as an example

  5. Show step by step how such work (including research, calculations, and conclusions) should be organized

  6. Discuss the results and give instructions for other planets

  7. Print out some images and data, and pass them out for a homework assignment

  8. Organize summary discussion and give hints to students on how to make conclusions

If time for this unit is limited, you can organize group work by assigning images and data concerning different planets to different groups. At the end of the unit small groups will present their calculations in front of the class, and then discuss similarities and differences between various planets.

Another approach to this interesting material is merely to supervize students' research by giving them short instructions on how to work with the Self-Study Guide, and by answering questions if there are any.

At the end of the unit students will be able to answer the questions from the work sheet. You can use it as a pre-test, post-test, or both.

Worksheet ButtonWork Sheet

To teach the angular velocity section, you may want to use a globe or a basketball tied with twine and hung up so that you can spin it. It can be used to demonstrate to students how to figure out the time it takes to make one turn.

You can also try turning the lights on and off to simulate seeing only part of the planet's rotation. You could even put some "clouds" between your young astronomers and the planet "Spaulding."
