In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

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.

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 UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

Can gelatin (like Jell-O ®) change the speed of light?

In this space science activity, learners explore transits and the conditions when a transit may be seen.

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

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

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

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

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

In this activity, learners investigate the properties of graphene and graphite.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

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

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.
