• Painted Dinosaur Eggs Craft

Supplies Needed to Make this Fizzy Dinosaur Sensory Bin:

• Silicone Egg Mold
• Mini Dinosaur Toys
• Baking Soda
• Water
• Vinegar
• Plastic Containers

How to Make a Dinosaur Eggs Sensory Bin:

Fill the silicone egg mold with water.

Balance the dinos across each egg so the feet are in the water.

Leave overnight to freeze.

Fill a container or bowl with baking soda.

Fill the second container with half vinegar and half water.

Take iced eggs out of the tray.

Dip ice in baking soda.

Place the dino in the vinegar tray, and watch it fizz while it “hatches.”

The Science Behind the Fun

When your preschooler adds vinegar to the baking soda-covered ice eggs, they’ll witness an exciting chemical reaction. The acetic acid in the vinegar reacts with the sodium bicarbonate in the baking soda to produce carbon dioxide gas.

This gas forms bubbles, creating the fizzing effect that kids find so fascinating. It’s a safe and fun way for them to learn about chemical reactions and states of matter.

This reaction is a perfect example of a base reaction, where an acid (vinegar) reacts with a base (baking soda) to form a new substance—in this case, sodium acetate, water, and carbon dioxide. It’s a great way to introduce young children to simple science concepts through sensory play.

 

Tips:

• Add a little food coloring to the vinegar/water mix for a fun effect.
• If you let the eggs sit so they melt just a little, the layer of water will help the baking soda stick.
• If you don’t have an egg-shaped mold, you can use any ice tray with big enough cubes or even a muffin tin.
• If you want a little less fizzy, mix two parts water with 1 part vinegar.
• If it stops fizzing, add more vinegar until it starts working.

Creative Variations and Dinosaur Craft Ideas

To make this activity more engaging, you can create a larger batch of baking soda eggs in different sizes. Depending on the size of your dinosaurs, you can even experiment with different shapes.

If your child is a big dinosaur fan, try incorporating cloud dough into the mix for a sensory activity beyond just the fizzy eggs. The soft, moldable texture of cloud dough pairs perfectly with the harder baking soda eggs, offering a contrast in sensory experiences.

Another creative way to enhance this activity is by adding bath bombs to the mix. These can create even more fizz and add delightful scents, making the sensory play more immersive. You can also incorporate a discussion about the chemical formula of sodium bicarbonate (NaHCO₃) and how it’s used in everyday life, like in baking and cleaning.

Dinosaur Sensory Bin

After the last egg has fizzed and the final baby dinosaur has been discovered, take a moment to talk to your preschooler about what they observed. Please encourage them to describe the vinegar reaction and the egg-dissolving process. This is a great way to reinforce the science behind the fun and to spark a sense of wonder about the natural world.

The Fizzy Dinosaur Eggs Sensory Play Activity is not just an exciting way to engage your preschooler in creative play; it’s also a fantastic opportunity to introduce them to basic science concepts in a fun and interactive way.

This activity fosters curiosity and learning by combining the thrill of uncovering hidden dinosaurs with the wonder of a chemical reaction. The hands-on nature of the experiment also helps develop fine motor skills, making it a well-rounded educational experience.

As you watch your little one delight in the fizzing, bubbling reactions and the joy of discovering mini dinosaurs, you’ll create memories that both of you will cherish. Whether you’re looking for a rainy-day activity, a special project for dinosaur enthusiasts, or a fun way to spend quality time together, these fizzy dino eggs will surely be a huge hit.

So go ahead, gather your supplies, and let the prehistoric adventure begin! With just a few simple ingredients and a sense of wonder, you and your child can explore the magic of science together—one fizzy egg at a time.
