We have been learning about rainbows in kindergarten this week. How they are formed, the intricate science behind them, and of course Gods great promise attached to them.  We learned that when sunlight hits certain water droplets rainbows are formed.  We did A LOT of fun rainbow themed activities this week. The class voted on their lesson and they chose this fun STEAM activity called M&M science rainbow.  

The kids arranged various patterns of M&Ms in a large circle on the edge of a plate. We gently added enough water to the middle of the plate until the water was touching all of the M&Ms. Over the next few minutes the students watched as their own beautiful rainbow formed right before their eyes! 

We learned that the hard shell of the M&Ms is made with water soluble colors. When the water touched the M&Ms, the colors began to dissolve and run into the water. Because of the shape of the plate and the positioning of the M&Ms, the colors had nowhere to go except into the middle of the plate, forming a beautiful rainbow as they do.
