I saw many posts about rainbow bottles from other blogs so I thought I would try a twist on this activity in my preschool classroom. The students loved it and were quick to learn the colors of the rainbow — in order. ROY G. BIV.
We filled plastic bottles about 3/4 of the way full with water. Added food coloring to each bottle. We were able to use our color wheel on the wall that we made painted a few months ago since some of the rainbow colors require mixing two colors together.
We learned the name: ROY G. BIV to learn the colors of the rainbow in order. Red. Orange. Yellow. Green. Blue. Indigo Violet.
The students had a great time scrambling the bottles and lining them back in the correct order. They even tested their friends to see if they could line them in the correct color order.
