This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.
