Left paw right paw

Do you think left-handed people have characteristics that are different from right-handed people? It seems that right-pawed dogs have certain characteristics that make them better Guide Dogs, but how do you find out whether your dog is right-pawed or left-pawed to begin with? Watch this experiment to find out!

Coffee spill

When you walk with a glass or a cup filled with liquid, do you find yourself spilling some of the liquid? Some scientists have studied why this happens and how best to avoid it.

Do dogs really care?

We'd like to think our dogs offer us comfort when we get upset or injured. Can the 'classic test' of empathy in humans tell us something about dogs? The reporter investigates the phenomenon of empathy: the ability to be aware and sensitive to the feelings of others from their perspective.

Seeing red: what is the red-eye effect?

Have you ever wondered what causes that annoying 'red-eye' in photos taken with a flash? How can you avoid or lessen it? Marko Moutafis uses eye models as he takes us through a lively demonstration to help answer these questions. He entered this video into the 2013 Sleek Geeks Eureka Science School Prize competition.

Density Simulation (sk-Intel)

This resource is in the style of an 'authentic' scientific investigation. The investigation is set in a crime lab where finding the densities of the various items can solve the crime. The tool enables students to explore mass and volume for a variety of solids and liquids and hence determine their densities.
