Easy Volcano Experiment
All you need to try this simple watermelon project are a few simle materials that you already have on hand. This kitchen science project is perfect for busy families as you can do this summer science activity in just a couple minutes with common things you already have on hand!
- watermelon – any size you like
- knife (for adult to use and supervise)
- spoon or scoop
- 1 cup baking soda
- 1/4 cup dish soap
- red food coloring
Start by preparing your watermelon to become a volcano. You can use any size of watermelon you like, just adjust the baking soda and vinegar accordingly for a big erruption! Cut a hole in top of watermelon that is just big enough to scoop, but the smaller the hole, the better for your volcano erruption as the lava will all be forced up the hole. Scoop out the inside like you carve a pumpkin. The reason we scoop it out isn’t for the science experiment with a watermelon, it is to avoid being wasteful with food! All we need for this watermelon activity is the watermelon container or shell, so-to-speak.
When you are ready for your erruption take your watermelon fruit outside or put on a tray with the surrounding surfaces covered – just in case! Now add baking soda, dish soap, and red food coloring (the more the better for a deep red color).
NOTE: You don’t need the dish soap to make the summer science experiment work, but it will make it bubble!
Pour in vinegar, about 1-2 cups, until you get some fun fizz starting to come up.
Watermelon Activities for Preschoolers
The volcano will begin to fizz and flow the “lava” from the inside down the side of the watermelon!
Your kids will love this fun and silly summer experiment!
Easy Summer Activity
Make sure you do this easy summer experiment on a baking dish with a lip or outside to contain all the red lava that comes out.
Baking Soda and Vinegar Reaction
This easy summer science is super CHEAP! Just use a watermelon you were going to eat anyway, and add some inexpensive baking soda and vinegar, some food coloring for color, and wala!
Vinegar and Baking Soda Reaction
If your kids can’t get enough of this science experiment, it’s normal. Ours begged to do it again and I was happy to oblige! Just dump in more baking soda and vinegar, plus food coloring and dish soap if you wish. No need to rinse or clean the tray unless you are out of room on the tray. That’s part of why we like to do our project outside. As you can see ours was more pink the second time because I used most of our food coloring the first time around. But guess what, the kids didn’t care – they though it was still super cool and giggled with excitement.
Summer Activity for Preschoolers
So what is happening in this cool fizzy chemistry experiment? Basically you are creating an acid and a base experiment. The vinegar is an acid and the baking soda is a base. When they mix they produce carbon dioxide. This fizzing gas will take up more and more space forcing the liquid in your watermelon to be forced up and out to create room for all the newly created CO2.
