In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

Why should we wear masks? Do masks work? Do some masks work better than others? Learners find out in this activity.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.
