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

In this hands-on botany activity, learners sprout vegetables in film canisters.

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.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this outdoor activity and/or field trip, learners investigate the behavior of hopping animals.

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 experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

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

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this outdoor mapping activity, learners explore where plants grow and map plant-distribution patterns.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

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

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

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

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

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

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.
