Meet the BFFs: four fundamental forces

We all know something about gravity, but what about the other fundamental forces of physics? Explore the properties of two familiar forces experienced in daily life, and of two less familiar ones. How do they interact, and what keeps everything from falling apart? This video was Kate Dent's entry into the 2013 Sleek Geeks ...

Optics and images: plane mirrors

Position an object and a flat mirror to reflect light rays and produce images. Predict the size and position of the reflection produced. This learning object is the first in a series of three objects that progressively increase in difficulty. The series is also packaged as a combined learning object.

Light and reflection: light rays

Investigate whether light rays always travel in straight lines. Rotate circular walls, each of which has a single opening. Position the walls so that light from a central bulb can be seen by a person outside the walls. Make shadows by placing a range of objects between a light source and a screen. Position shapes to make ...
