In this math activity, learners use a variety of sensory modalities to gain experiences with identifying, describing and creating repeating patterns.

In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

Learners use two mirrors to explore how images of images of images can repeat forever.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.
