In this activity, students compute the strengths of the gravitational forces exerted on the Moon by the Sun and by the Earth, and demonstrate the actual shape of the Moon's orbit around the Sun. The lesson begins with students' assumptions about the... (View More)

This is a lesson about radiation and the various sources of radiation that a spacecraft may encounter in its journey. Learners will calculate their annual exposure to high-energy radiation, identify sources of high-energy radiation, and explain why... (View More)

In this short demo/activity, a balloon with baking soda in it is stretched over the mouth of a flask or bottle containing vinegar. The balloon is tipped so that the baking soda falls into the vinegar, and the reaction creates carbon dioxide, which... (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 a detailed lesson about space and how Earth fits in it. Learners will consider the essential question, "What is space?" Activities include small group miming, speaking, drawing, and/or writing about space and the evidence for ice in space.... (View More)

This is an article about detecting gravitational waves. Learners can read about how the Laser Interferometer Space Antenna (LISA) is detecting gravitational waves. An activity is included about how to build a mini-LISA and use it to explore the... (View More)

A simple experimental apparatus made of rubber band and books is used by student teams challenged with demonstrating the concepts of friction, force, and inertia. This resource is from PUMAS - Practical Uses of Math and Science - a collection of... (View More)

This worksheet, suitable for pre-readers, directs students to categorize pictures as sources of either natural or artificial light. The resource is part of the teacher's guide accompanying the video, NASA Why Files: The Case of the Mysterious Red... (View More)

This resource consists of a template that can be used by students to cut out a book in a rainbow shape. It is suggested that students write a book documenting what they know about the visible spectrum. The resource is part of the teacher's guide... (View More)

In this demonstration, students learn how fiber optics work by observing a model using gelatin and observing how the internal reflection of light allows light to bend within the system. The resource is part of the teacher's guide accompanying the... (View More)
