This is a fun hands-on activity that teaches kids about the chemical reaction between baking soda and vinegar while also incorporating Dinosaurs.
I first found this fun activity off of Pinterest and on the blog of Simple Everyday Mom. I made few changes that worked for me so I've included them here. I've linked her blog here so you can check out all of the fun activities that she's also created.
1. In a plastic up, mix 3 Tablespoons of baking soda, 1 teaspoon of cornstarch, 2 tablespoons of water, and 2 drops of food coloring.
Repeat this step for each different color you wish to use.
2. Using gloves to prevent hands from being stained, scoop out the colors you wish to use and create a half egg in your hand. Place the small plastic miniature dinosaur on top of it.
3. Scoop out the paste in colors of your choice to create the other side of the dinosaur egg. Squish the sides together.
NOTE: This was so much messier than I thought it was going to be but it was fun and the kids love the final product to use in their fizzy science experiment.
4. If your egg is too liquid, you can add sprinles of baking soda and corn starch. Even once the egg is complete, I still sprinkled the ingridents on top if I saw that the egg was a little too runny.
How 2 Play:
Now for the Fun!
Set up the activity on an activity try with droppers and a bowl of vinegar.
Encourage the children to drop the vinegar on the Dinosaur Eggs to watch them hatch. The fizz that is produced from this experiment is a chemical reaction between the baking soda and the vinegar, producing a carbon dioxide gas.
You can add liquid dish soap to the activity to create more of the foaming action.
Here is a fun link to Science is Fun explaining more of this reaction.
