In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.

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.

Did you know that using a lens one can bend light to make pictures of the world? It's true!

With little more than a flashlight, a straw, and a plastic lid, make an observatory so you can see the amazing colors in bubbles.

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

This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.

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 about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this activity, learners investigate the effect of heat on a reaction.

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