Simple Science: Growing Rainbow

Growing Rainbow Experiment
This experiment gives plenty of observation time as kiddos watch 2 sides of a rainbow grow together and make one big rainbow!  Find more about this experiment here!
 Material ready!  Kiddos will love working with the markers!
Draw a rainbow on each side of the towel!  Don't leave too much space between the 2 rainbows or they may not 'grow together' well.
Fold the coffee filter.
Put each side in a cup with a bit of water.  Then it's observation time!  This would also be a great time to read the paired book....The Color Monster!  This is a great book to help kiddos relate to emotions.
Wow!  Look at the rainbows growing together!
