# The Moon Orbits the Sun?!

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)

# The Rubber Band Problem

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)

# Natural or Artificial

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)

# Rainbow of Knowledge

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)

# The Bendable Light

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)

# Roll Out the Frequency

In this activity, students use marks on a 1.4 m strip of paper to simulate light wave frequencies and measure the time it takes for different frequencies to pass through the "viewer" made from a manila folder. Students learn that different colors of... (View More)

# Traveling the Straight and Narrow

In this activity, students build an obstacle course for a flashlight beam using file cards, hole punch, clay, and observe that light travels in a straight line and demonstrate the concept of light extinction. The resource is part of the teacher's... (View More)

# Transparent, Translucent and Opaque

In this activity, students examine everyday objects with a flashlight and determine if they are transparent, translucent, or opaque. Common household materials such as wax paper, plastic wrap, aluminum foil, tissue, and food coloring are required.... (View More)
