Intended for use prior to viewing the Science on a Sphere film "Water Falls," this lesson introduces students to Earth's water cycle and the importance of freshwater resources.

This is an activity about the atmospheric conditions (greenhouse strength, atmospheric thickness) Mars needs to maintain surface water. Learners will use a computer interactive to learn about Mars past and present before exploring the pressure and... (View More)

Through an analysis of data sets on four parameters - sea ice totals, sea surface temperatures, near surface temperatures and surface type - students must decide whether the Arctic is experiencing climate change and predict any potential effects on... (View More)

In this activity, students work in teams to calculate relative air mass and demonstrate how solar elevation angle affects the intensity of light that reaches an observer on the ground. The resource includes a student data sheet. This learning... (View More)

In this activity, students create a model of sea floor spreading using two sheets of white paper and a metric ruler. The paper strips are pulled through a slit representing a mid-ocean ridge and divergent plate boundary. The model mimics how molten... (View More)

In this demonstration, an egg is used as a model of the Earth. The egg is tapped gently, to create cracks in the shell. The pieces of shell are analogous to the Earth's plates, and the cracks are used to explain plate boundaries. Using the egg, the... (View More)

Students become familiar with strike-slip faults, normal faults, reverse faults and visualize these geological structures using cardboard or a plank of wood, a stack of books, protractor, and a spring scale. The resource is part of the teacher's... (View More)
