In this activity, learners determine the necessary conditions for pea seed germination.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

In this activity, learners investigate how some butterfly wings get their color.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

Learners demonstrate how water can distort, refract and magnify 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.

Like water drops in falling rain, a CD separates white light into all the colors that make it up.

In this activity, learners create a cylindrical mirror to see themselves as others see them.

In this activity, learners use simple materials to create giant bubbles.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this activity (on page 2 of the PDF under GPS: Light and Color Activity), learners will see the illusion of colors produced by a rotating black and white image known as Benham’s Disk.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

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 quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this activity, learners discover how sediment is affected in an oil spill. Learners investigate the differences between heavy and light oil as well as the differences between different sediments.

In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.
