In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this math activity, learners experiment with the concept of symmetry.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity, learners investigate how geometry plays a role in perspective.

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
