Creative Thinking Prompt: Create a Rainbow

Creative Thinking Prompt: Create a Rainbow

Spring is here! As the old saying goes April showers bring May flowers. And with those showers come rainbows.

Water droplets act as a prism through which the sun’s ray travels. Each ray of contains the colors of red, orange, yellow, green, blue, indigo, and violet. A ray travels in a straight line. When the ray hits the water drop, the light waves refract, separating and bending into different color wavelengths to display a rainbow.

Creative Thinking Prompt: Create a Rainbow

First, think about what can cause light to bend. Make a list. Here are a few to get you started.

  • Spilled oil
  • Blowing bubbles
  • Diamond ring

Second, think about what materials you could use to experiment with to create a rainbow.

Third, gather materials and try creating that rainbow.

Fourth, what steps are needed for your experiment?

Fifth, conduct your experiment.

Sixth, which materials were more successful at creating a rainbow? Which materials were not successful? Why do you think those materials were and were not successful?

Seventh, if you were to do this experiment again what might you do differently?

Think Deeper:

Use your imagination to create a rainbow from other unusual materials such as this fudge recipe.

Make a list of all the wonders you have about a rainbow. For example, I wonder if rainbows can form a circle.  Go to the library or ask a science teacher to find out answers to your wonder questions.
