In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

Learners demonstrate how water can distort, refract and magnify light.

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

“Exploring Earth: Investigating Clouds” is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light.

In this activity, learners make their own heat waves in an aquarium.

In this activity, learners discover how solar energy can be used to heat water.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

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