This is a lesson about impact craters; the relationships between crater size, projectile size and projectile velocity; and the transfer of energy in the cratering process. Learners will create plaster of Paris or layered dry impact craters and... (View More)

In this activity, learners will determine the factors affecting the appearance of impact craters and ejecta on the Moon. Extensions are listed. This activity is in Unit 2 of the Exploring the Moon teachers guide, which is designed for use... (View More)

In this demonstration, a soda bottle, paper and straws are used to show learners that air has mass and takes up space. The activity is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and... (View More)

This resource uses an everyday example of walking a dog as a context where students can observe changes in shadows over the course of a day, and deduce that light travels and tends to maintain its direction of motion. The activity is from PUMAS -... (View More)

Audience: Elementary school
Materials Cost: Free per group of students

This is an activity about spectroscopy. Learners make their own spectroscope and measure the wavelengths of spectral lines. Then, they will record the colors, patterns, and wavelengths of the lines from various light sources. This activity requires... (View More)

This is an activity about telescopes. Learners will first measure several circles to determine their diameters and calculate their areas. Afterwards, they will cover each circle entirely with pennies and record how many pennies are needed for each... (View More)

This is an activity about gravity. Learners will fill out a questionnaire to assess their ideas about how the Earth is shaped and how things fall here and at different places around the planet. Then, in small groups, learners will discuss how... (View More)

This is an activity about the Doppler effect. Learners will use long springs or ropes to examine the frequency and wavelength of various waves. Then, they will observe a demonstration of the Doppler effect for sound waves, using this understanding... (View More)
