Foaming Rainbow Science Experiment for Kindergarten

  •  

We have been trying to do about one science experiment per week for our kindergarten homeschool BUT I have been really really horrible about posting on them. To be honest, I have been using an old kids science experiment book for most of the projects and many of them have been duds.

Netflix: Emily’s Wonder Lab

This project wasn’t from the book, though. It inspired by the new Netflix show: Emily’s Wonder Lab. Toward the beginning of the school semester we began watching this show as an added bonus because it is kinda like the “bill nye the science guy” videos of our children’s era. This show has so many rainbow colors and it happy and features tons of kids. It is just a lot of fun for home school, or a virtual learning environment!

Supplies:

For this project the supplies you will need are:

  • vinegar
  • baking soda
  • paper towels
  • food coloring
  • ceramic plate.

How to set it up:

The set up is so quick and easy! The kiddos can help out with every single step!

  • Lay out some paper towels to make for easy clean up if you have any overflow.
  • Place the ceramic plate in the middle of the paper towels.
  • pour baking soda onto the plate. Enough to cover the bottom like the picture shows.
  • Then drip the food coloring into the baking soda. RANDOMLY.

Activate it:

To set the experiment as a go you just pour the vinegar onto the experiment. start out with a small amount. Nothing that is going to run over the edges of your plate. 1/8 to 1/4 of a cup to begin with and watch it fizz and change colors. You can always add MORE vinegar. There is no direct measurements set with this experiment though, because everyone will probably use a different sized plate or bowl to start out with. AND that is fine because it makes everything flexible. YOU cannot go wrong with this experiment.

ADDING MORE VINEGAR as it reacts:

If there is more underacted baking soda, just add more vinegar. Watch as the colors begin to flow together and everything is fizzing. Kids love the fizzing and the risk of it overflowing! If you are feeling brave, pick a container that it WILL overflow with. The squeals of laughter when you do this are priceless.

End of the Reaction and the Clean Up:

This last photo features the end of our reaction. AND now, lets talk clean up. DID you know that baking soda and vinegar is actually used to clean out pipes and toilet clogs. You can in fact use it in place of drain-o. FUN RIGHT? It is safe to pour down the sink with lots of water, or into the toilet to help flush out the pipes (add a bit of water). So, dump it and rinse it with lots of water. Your done, throw the plate in the dish washer or whatever you do with it. Throw away the paper towels and you are all cleaned up.
