In this activity, learners use gelatin as a lens to investigate the properties of laser light.

In this activity, learners overlap the three primary colors to see how all other colors are made.

In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, learners explore how nanosized structures can create brilliant color.

This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.

In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.

In this lab (Activity #1 on page), learners explore how we see color.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.
