Comparing Cosmic Cameras

Learners will take and then compare the images taken by a camera - to learn about focal length (and its effects on field of view), resolution, and ultimately how cameras take close-up pictures of far away objects.

Reading the Clouds: CloudSat Poster

This poster illustrates and describes types of high-, low-, and mid-altitude clouds. Poster back has article and activity related to Earth's water cycle, as well as a cloud identification quiz and a water cycle crossword puzzle.

How Can the Little Moon Hide the Giant Sun? Exploring Size and Distance

This is an activity exploring the concept that distance affects how we perceive an object's size, specifically pertaining to the size of the Sun and the Moon as seen from Earth. Learners will complete a hands on activity where two balls of differing sizes stand in for the Sun and the Moon.

Chesapeake Bay: Resource Use or Abuse?

The use or abuse of the Chesapeake Bay is examined and discussed in the form of a student role-playing activity. Each student gathers relevant background information and formulates questions from briefing cards included in the investigation.

Putting the Electromagnetic Spectrum Together

This activity deepens student understanding of the electromagnetic spectrum, enabling students to detect and consider wavelengths other than visible light.

Beautiful Earth Water Density Experiments

Designed as either a demonstration or an investigation for use in a formal or informal setting, this activity focuses on the effects of water density on water's movement. A list of materials, along with the instructions for building the apparatus needed, are included.

Earth- A Matter of Gravity

In this problem set, learners will analyze a map of Earth's gravity field derived from satellite data to answer questions on gravity averages and anomalies in certain regions. Answer key is provided.

Making Months

In this activity, students develop reasonable calendar designs for an imaginary planet using factoring as a problem solving strategy.
