Multiple activities illustrate the concept of changes in bodies of water over time. Emphasis is placed on the use of remote sensing to monitor changes in water bodies that are due to climate change, erosion, drought, human intervention and natural... (View More)

Learners will make a model of the Moon's surface and consider the geologic processes and rocks of each area. This activity is in Unit 2 of the Exploring the Moon teachers guide, which is designed for use especially, but not exclusively, with the... (View More)

Learners will build a biosphere that is a balanced, self-enclosed living system able to run efficiently over a long period of time. This activity is in Unit 3 of the Exploring the Moon teachers guide, which is designed for use especially, but not... (View More)

Learners will use water balloons to demonstrate meteorite impacts, use geography to assess various terrains for meteorite recovery, attempt to recover simulated meteorite fragments, make experimental predictions, graph the results, and draw... (View More)

This is a lesson about observing and examining meteorites in a Meteorite Sample Disc. Learners will practice scientific techniques, develop skills in acquiring data through the senses, observe, examine, record, and sketch data, use magnifying... (View More)

This is a lesson about planet formation. Learners will observe and describe differentiated samples in the Meteorite Sample Disk (or photographs), conduct experiments to model the separation of light and heavy materials within a planetary body,... (View More)

This is a lesson about the effects of large impacts. Learners will use critical thinking skills to evaluate and apply data from a narrative to a scientific selection process, will demonstrate or visualize simulations of some of the effects of a huge... (View More)
