This is a lesson about planet sizes. Learners will demonstrate the size (volume) differences between Earth, Earth’s Moon, and Mars. An extension to estimate the distance between the Earth and the Moon, and the Earth and Mars, using the scale of... (View More)

This is a lesson about society and space exploration. Learners will survey the public about their different opinions about space exploration and the use of robotics in space exploration. Then they will represent and analyze the results. This is... (View More)

Students will use various objects in the classroom to experiment with nonstandard measurement. They will make estimates and test them out. Then, working in pairs or small groups, students will use a ruler or a measuring tape to become familiar with... (View More)

In this activity, students produce a land cover map of a 15 km x 15 km GLOBE study site from hard copies of Landsat satellite images. Students place clear transparencies over the Landsat TM images and use markers to outline and classify areas of... (View More)

This is a lesson about radiation and the use of the scientific method to solve problems of too much radiation. Learners will build snow goggles similar to those used by the Inuit (designed to block unwanted light, while increasing the viewer’s... (View More)

This is an activity about the Aurora Borealis or Northern Lights. Learners will plot the Auroral Oval in the northern hemisphere and determine the height of the northern lights using Carl Stormer's triangulation method. This activity corresponds to... (View More)

This is an activity about observing the Sun. Learners will construct a pinhole projector to project an image of the Sun, observe and record the size of the projected image, and calculate the diameter of the Sun using the measurements and a known... (View More)

This is an activity about planetary sizes and distances. Learners will construct a scale model of the Earth, Earth’s Moon and Mars in relation to each other using balloons. They will use this model to predict distances and reflect on how... (View More)

Water supply in the Southwestern United States depends on snow. Students discover its importance through analysis and evaluation of data, satellite images, space shuttle photos, and ground-based observations, and then apply their findings in a... (View More)
