In Science today we have learned all about refraction. Refraction is where light waves travel at a different speed when they go through other transparent materials, such as water or glass. This causes the rays of light to change direction and bend. 

Refraction creates illusions. Because light bends when it travels between air and water or glass, objects seen through these materials look bent or distorted. Objects can look bigger or smaller. They can also look as if they have turned the opposite way or flipped upside down. We carried out several investigations to see refraction in action!
