In this lesson we will be learning about PS3 A- Definitions of Energy, PS3 C- Relationship between energy and forces

In class we will be learning of refractions and light and how it is a form of energy. We will be experimenting with prisms, light and rainbows.

Light is made of tiny photons which contain lots of energy. … Light is also called electromagnetic radiation when speaking of light other than visible light. Of all the forms of radiation and light on the electromagnetic spectrum, humans can only visibly see a very small amount of light.

A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multi-colored circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
