refraction

Refraction means the bending of waves. It is frequently mistaken for reflection, which is the bouncing of waves off of a surface. Refraction happens because waves (such as light waves) travel at different speeds through different materials--as the wave passes from one material, or medium, to another, it bends as it either speeds up or slows down.

Rising From the Ashes

A new year, a new location, a brand-new school, and a new set of students—but the Explorers are again investigating the wonders of science and nature.

An Absorbing Activity

In February 2010, the Explorers did some slippery investigations of physical changes.

Secret Rainbows

In February 2009 the Explorers spent a session investigating the nature of light. They learned that white light is actually anything but white, and that nearly every beam of light has a secret rainbow hiding inside it.
