The Hidden Lives of Galaxies - Classroom Activities
Activity #7 - Dark Matter Possibilities
In this activity, students investigate one specific topic related to dark matter using available resources. Students will organize their findings and present this information in a creative and engaging fashion.
Directions:
Organize students into groups of about four students each. Assign each group one of the following topics related to dark matter (you may need to assign several groups to the same topic).
- Massive Compact Halo Objects (MACHOs)
- Weakly Interacting Massive Particles (WIMPs)
- Hydrogen Gas
- Massive Compact Halo Objects (MACHOs)
The Student Instruction Sheet (see page 37) gives students a series of questions to guide the investigation of their topic. It also lists suggested resources to use. Ask students to gather their information, citing their sources in a bibliography. Allow one to two days for the students to carry out their research.
Ask students to prepare a presentation to the class. Some possible presentation formats are on the Student Instruction Sheet. Feel free, of course to suggest and/or encourage others.
