Newton Wheel | STEM This activity, from Solar Spark, allows students to investigate light and the eye. A template is provided that students can colour to produce a Newton Wheel. White light is made up of lots of different colours and by spinning the colours on the disc, the eye combines the spinning colours and sees the disc as if it were white. The resource can be used to illustrate: * light and colour * how the Disappearing Color Wheel | Science Experiments | Steve Disappearing Color Wheel. The wheel is covered in the primary and secondary colors, but give it a spin and they vanish from a rainbow to white. When Sick Science! first got its start, we introduced an experiment called the Color Mixing Wheel. This spinning science toy was a great way to show you what happens when the primary colors blend Bigshot: Fun - Buildables - Colorwheel Sir Isaac Newton discovered that white light is composed of many colors in the late 1600's. He demonstrated that a beam of white light passing through a prism separated into at least seven distinguishable colors − the colors that we see in a rainbow. He was also the first to suggest the color wheel experiment described above.
