The Science Behind Baking Soda Experiments

A baking soda and vinegar science activity is a fun way to excite kids. It is an easy science activity that’s ideal as a basic introduction to chemistry and scientific concepts for preschoolers or young children in a classroom setting.

Let’s break it down:

When an acid (vinegar or acetic acid) reacts with baking soda (sodium bicarbonate), an acid-base chemical reaction occurs.
A new product is formed during this reaction. This product is carbon dioxide gas which can be seen through the foaming or fizzing bubbles.
During this reaction, all three states of matter are present which can be observed through physical changes: solid (baking soda), liquid (vinegar), and gas (carbon dioxide).

Fizzy Baking Soda Easter Eggs

This fun STEM activity is easy to put together and inexpensive! It can be a fun activity for the Easter holiday, a way to engage kids in the classroom with new concepts, or just a hands-on activity that targets essential skills.

Supplies

Plastic easter eggs
Baking soda
Vinegar
Glitter (optional)
Food coloring
Large tray or container
Plastic squeeze bottle or dropper

Instructions

STEP 1: Add baking soda to a plastic easter egg

Set up plastic eggs in a tray or container (this will make clean-up time easier). Add approximately 1 tablespoon of baking soda to each plastic egg.

STEP 2: Add food coloring to the baking soda

Add any color food coloring to the eggs. I added 2 drops to each egg.

I suggest using different colors to make it more visually stimulating. You could add more drops of food coloring or use gel food coloring to achieve a more vibrant color.

STEP 3: Add glitter

add glitter to baking soda mixture (optional)

Add a sprinkle of glitter to make the experiment more exciting and magical. Adding glitter is totally optional and this part can be skipped.

STEP 4: Pour vinegar on the baking soda mixture

Now it’s time for the fun part! Add vinegar into a plastic squeeze bottle and pour it onto the baking soda mixture.

Another fun alternative is to add vinegar to a small bowl and use a dropper.

Tip: If completing this activity with a few kids, give each child a single egg and a small bowl of vinegar. Keep a bowl or plastic cup of vinegar on the side to re-fill the bottles as needed.

STEP 5: Observation and Results

The kids will be able to observe the fizzing which is the end result of the chemical reaction.

Different colors and ratios of food coloring mean that each child’s experiment will look unique.

Baking Soda and Vinegar Tips

Add dish soap or dishwashing liquid to create more foam and to slow down the reaction.
Use lemon juice if you don’t have vinegar on hand or don’t like the smell of vinegar.
If you don’t have plastic eggs, you can use ANY mold or container.
If you have a large group of kids, I suggest distributing one plastic egg and dropper or plastic bottle per child. The kids could also pair up for this activity. Another option is to do this as a demo but an interactive experiment is always the best!
Use droppers and squeeze bottles to engage and develop fine motor skills. They can also just pour vinegar from a cup but these are more stimulating!
