Such a fun rainbow science experiment! I love that it smells good, too!

explore rainbow science that fizzes and smells delicious


Materials

Baking soda

Jell-O in every color of the rainbow (well, except indigo)

Water

Ice cube trays

Vinegar

Squeeze bottles

Eye droppers

Food coloring or liquid watercolors


Two versions of a scented rainbow science and sensory activity
The left-hand photo shows the rainbow ice made with just Jell-O. The right-hand photo shows the rainbow ice that had food coloring added to it.

Prep

Start out by making the scented baking soda “ice” cubes. For each of the colors (red, orange, yellow, green, blue, purple), I used the following “recipe”:


  • 3/4 cup baking soda
  • 2 tablespoons Jell-O powder
  • 1/4 cup water
  • Food coloring (optional)

Combine the baking soda and Jell-O powder in a bowl, then add the water and mix. To make the colors brighter, add a few drops of food coloring to the water before pouring it in. This results in a somewhat pasty mixture, so don’t be alarmed that it’s not a liquid. If it’s too thin it won’t set correctly.


Use a spoon to add the mixture to the ice cube tray. I found that the above recipe gave me enough to fill one ice cube tray per color. If needed, tap the ice cube tray on your counter to ensure the mixture settles into the tray evenly.


Place the ice cube trays in the freezer. Once they’re frozen through, remove from the freezer and get the rainbow science going immediately. I’d suggest arranging the cubes in rainbow order.

Exploring the scented rainbow

Now it’s time to bring on the condiment bottles and eye droppers filled with vinegar! Let the children pour and squeeze as they sit fit. Be sure to listen closely as they make observations about what they’re seeing. Ask open-ended questions to really get the children thinking. Encourage the children to experiment to find out the answers to their questions along the way.


I’ve done this experiment a few times with the kids at home, and they already have plans for another try later this week! Here are some of the comments and questions I’ve heard:


  • “I can hear it fizzing! Can you hear it fizzing? Hey, what’s making the fizzing sound?”
  • “I can smell the vinegar right here [putting nose right by the bowl of vinegar], but I can’t smell it once it’s all mixed up there [pointing to the pan with the experiment in it].”
  • “It feels all cold and squishy now!”
  • “Why’s it all turning brown? Is it supposed to turn brown when all the colors are together like that?”
  • “Hey, I need a new pan please. With lots of vinegar. And a towel probably. I’m going to just use some of the colors. Maybe it won’t turn brown this time.”

Placing blue and yellow baking soda cubes in vinegar yielded green once the reaction was complete!

The learning

This rainbow science experiment allows for an amazing amount of learning (for a variety of age groups)! Here are some of the topics I’ve discussed with preschoolers and elementary-aged children:


  • Colors – tons of color identification, along with a discussion of the order of colors in a rainbow
  • Color mixing – put just two colors into a pan and let the children see what happens when the colors dissolve and mix together
  • The physics of rainbows – while this rainbow science experiment doesn’t delve directly into light and wavelengths, the question “why are the colors in the rainbow always in the same order?” may arise and lead to a great opportunity to discuss this (and plan for further science experiments)
  • Chemical reactions – when baking soda and vinegar react, they create the gas carbon dioxide (which makes the bubbling and fizzing)
  • Endothermic reactions – when baking soda and vinegar react, the temperature lowers
  • Tons of sensory exploration – seeing, hearing, smelling, and touching! It’s a taste-safe experiment so there could be tasting, as well but it wouldn’t taste all the great!

Rainbow bubbles as part of a rainbow science experiment - I love the colors and the fact that it smells good!

Would your children enjoy our little rainbow science experiment? If you try it, I’d love to hear about how it goes!!
