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 activity, learners set up a night time insect observation station with a light and sheet.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

This activity uses a special paper that can create images with exposure to the Sun. Collect objects of different shapes and sizes and use them to make interesting patterns on your sun print.

In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.

In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.
