This is an activity to do when there is a solar eclipse!

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

In this hands-on activity, learners investigate the functional design of leaves on a tree.

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

This is an activity exploring color and color mixing.

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

In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

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 design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.

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

This is an activity about the behavior of light. Using simple, everyday objects, learners will discover that light moves in straight lines until acted upon by another object.

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

In this activity, learners investigate procedural memory.

This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity (page 3 of the PDF), learners will observe a physical change.

In this activity, learners explore how mirrors reflect light and change the way we see things.

In this activity, learners perform an experiment to find out what determines a flower's color.
