Extending the Rainbow - 1st Grade

Today in 1st grade we learned that the rainbow includes many colors we can not see as well as those we can. There are colors with very short wavelengths (ultra violet) and very long wavelengths (infrared). Heat and cold around us can be remapped with an infrared camera into the visible spectrum so we can see changes in temperature. We can paint with ice by moving it quickly (light to dark blue) or slowly (purple to black) over a period of time on a water-proof canvas. 

Ice Painting in 1st grade. The canvas stays coolest in spots where the ice stays the longest.
