This is a lesson about light in the outer solar system. Learners will demonstrate the effect of the inverse square law of illumination with distance and connect this to the functioning of solar panels at Saturn. Requires a silicon solar cell... (View More)

This is an activity about the size and scale of the Sun-Earth system. Learners will take an imaginary trip to the Sun by comparing images of the Sun and Earth at different points in altitude above the Earth. This is to ultimately conceptualize the... (View More)

This inquiry activity supports student understanding of the cause of light, heat and shadow, how to measure the passage of time, and how to use rules and other measuring tools. Students make observations using shadows, a meter stick, and a homemade... (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 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)

Students will "digitize" photographs of human faces using various grid sizes and shades of gray. Through this activity, they gain an understanding of image resolution and how much information is needed to answer various questions.This introductory... (View More)

Students critically interpret graphical data and evaluate and discuss the difficulties inherent in interpreting and forecasting long and short term trends in this introductory climate change investigation. Graphs of data needed for this exercise are... (View More)

In this investigation students explore how resolution affects information content on remotely sensed images, relate remote sensor resolution (pixel size) to information content, and gain an understanding of the information content of different kinds... (View More)
