Rainbow bottles

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.

    This is such an inviting activity! I featured it at the Living Montessori Now Facebook page and pinned it to my Rainbow Unit Study Board at http://pinterest.com/debchitwood/rainbow-unit-study/

    I have done a twist on this activity that never gets old with the kids. Start with your water, add a dishsoap such as Dawn (that has color to it…) and take a straw to blow bubbles into the water with the soap. Ask the kids what color they think the soap bubbles will be? Some will guess correctly and some will say the color of the soap. Then blow bubbles into the water. The bubbles will be large and sort of a hexogon in shape. Allow the kids to put the food coloring into the soap-bubbled water. It’s fun to watch the color follow the outline of the bubbles and once it hits the water its a whole new show! Very pretty. Follow the same process with each color. I always did the primary colors first and then asked the kids what would happen if we mix two colors together? What do you think we will get if we mix…. (you get the point). The kids love this activity. I would wait to see when the kids started to loose interest (but before interest was loss) and let the kids shake the bottles of course with the lids tightly secured. I’ve never had to glue lids. I would also ask the kids if I turn the bottle upside down where do you think the soapy bubbles will be, at the top or the bottom? I think I enjoy this activity just as much as the kids do!
    I love what you did with your lesson here. Thank you for sharing. Right now I have babies so it will be another year before I can do this activity with them. I can’t wait 🙂

    Very cool color learning activity! I love how the kids got to practice putting the bottles in the right order to make a rainbow.
