This is a lesson about distances in space. Learners will create an outdoor, to-scale model of the distances between the Sun, Earth, and Saturn. Next you will conduct a guided walk to Saturn - which gives students an understanding of how far away... (View More)

This is a detailed historical lesson about comets, distant icy worlds often visible to observers on Earth. Learners will consider the essential question, "What are comets?" They will practice observation and "noticing" skills as they enact a story... (View More)

This lesson is comprised of four parts grouped to enable student appreciation of the importance making accurate scientific observations, descriptions, and drawings. In part one, The Truth is Out There, students describe an object given to them by... (View More)

In this activity, students construct adding slide rules, scaled with linear calibrations like ordinary rulers. Students learn to move these scales relative to each other in ways that add and subtract distances, thus calculating sums and differences.... (View More)

Students create a physical model illustrating soil water balance using drinking glasses to represent the soil column, and explain how the model can be used to interpret data and form predictions. Using data from the GLOBE Data Server, they calculate... (View More)

This activity focuses on the question, What do active galaxies look like when viewed from different distances? Students work in small groups to learn about the small angle formula, construct a template, and use it to correctly measure the angular... (View More)

This is a brief activity about the mathematics of Mars. By playing this matching card game, learners will gain knowledge of Mars mathematical facts and vocabulary.

Students build a simple aneroid barometer that can be used to measure changes in air pressure. Materials required include a large jar, ruler, large balloon, 2 drinking straws, and clay. The instrument is used to track changes in air pressure, and... (View More)

This activity is about the discovery of water ice on Mars. Learners will record and graph temperature data and use a model of an ice-rich and ice-free surface on Mars to examine how ice content in the martian soil would impact the temperature of a... (View More)

This is an activity about the differences in thermal behavior between similar materials having different physical properties. Learners will measure temperature of two different surfaces; sand and stone; on a sunny day, make a series of temperature... (View More)
