September 29, 2024 / DIY / STEM Activities / Chemistry / Ages 3 - 5 / Fizzy Dino Eggs

A dinosaur activity perfect for young palaeontologists! These colourful dinosaur eggs and the crackling sound they make when the dinosaurs hatch are completely irresistible to children.

Age: 3-5
Time: 30 minutes + overnight drying
Mess Level: Messy

Materials Needed:

Food colouring
Baking soda
Spoon
Vinegar
Dinosaur toys
Water
Bowl
Tray
Disposable gloves

Arranged on a vibrant green surface are the ingredients and equipment needed for a fizzy dinosaur egg experiment. These include a small container of baking soda, several small bottles of coloured liquid, a measuring jug containing water, a small measuring cup, a spoon, a clear glass, a white plate on a grey tray, and a plastic glove. Three small plastic dinosaurs are also present, hinting at the experiment's outcome. The items are neatly organised, suggesting a prepared and organised approach to the activity.

Step-by-Step Instructions:

Make the shell. Pour baking soda into a bowl. Add a few drops of food colouring to a cup of water. Using a spoon, gradually add water to the baking soda, stirring until the baking soda forms a clumpy consistency.

On a bright green surface, a person's hands are shown adding a spoonful of red liquid to a bowl of white baking soda. Several small bottles of coloured liquid are visible in the background, along with a glass of liquid and some small plastic dinosaurs. A grey tray containing a plastic glove is also present. The scene depicts a stage in the preparation of fizzy dinosaur eggs, showcasing the careful addition of coloured liquid to the baking soda mixture. The overall impression is one of a fun and engaging science experiment.

Make the dinosaur eggs. Put on gloves, take some baking soda in your hand, place the dinosaur toy on top, then cover the dinosaur with more baking soda, shaping it into an egg form.

On a bright green surface, a person's hands, wearing disposable gloves, are carefully embedding a small yellow plastic dinosaur into a mound of pink, granular material. A white bowl containing a larger quantity of the same pink mixture is visible in the background, along with small bottles of coloured liquid, a measuring jug of water, and a small tray holding additional plastic dinosaurs. The scene clearly depicts a step in the process of creating fizzy dinosaur eggs, focusing on the careful placement of the dinosaur within the baking soda mixture. The overall impression is one of a fun, hands-on science project.

Let the dinosaur eggs dry. Place them on a tray to air dry for a few hours or overnight.

Four colourful, egg-shaped lumps of baking soda mixture rest on a light grey rectangular tray. Two are a pale teal, one is a pale yellow, and one is off-white. They sit on a bright teal background, next to a small brown plastic dinosaur and a small black plastic cactus. A yellow plastic tool, possibly for digging or sculpting, lies to the left. The overall impression is of a completed stage in a children's science experiment, specifically the making of fizzy dinosaur eggs, ready for the next step.

Start "hatching" the dinosaur eggs. Use a cup to pour vinegar over the dinosaur egg, or you can use a dropper to dissolve the egg bit by bit. Can you hear the fizzing sound? Observe the reaction between the vinegar and baking soda.

A hand gently places a small, yellow fizzy dinosaur egg into a tray filled with a bubbling, lime-green liquid. A small, dark grey plastic dinosaur is visible in the top left corner, alongside a yellow plastic tool. The egg is partially submerged, and the liquid is visibly fizzing around it, indicating a chemical reaction. The tray is rectangular and clear, allowing a clear view of the reaction. The bright green background provides a strong contrast to the yellow liquid and the egg. The overall image suggests a fun and engaging science experiment in progress.

You can also decide what to put inside the egg based on your child's interests.

Two fizzy dinosaur eggs, one pink and one blue, have erupted on a clear tray atop a teal surface. A yellow dinosaur emerges from the pink remains, and an orange dinosaur from the blue. The eggs have reacted with vinegar, creating a bubbly, frothy mess. The vibrant colours and the playful dinosaur toys create a visually engaging scene, indicative of a completed, successful science experiment. Bits of the egg mixture are scattered around the main clumps, showing the extent of the reaction.

The Science Behind It:

This is one of the classic acid-base chemical reactions. When baking soda (also known as sodium bicarbonate) and vinegar (also known as acetic acid) come into contact, a chemical reaction occurs, producing carbon dioxide.

When you pour vinegar onto the egg made of baking soda, the acetic acid reacts with the sodium bicarbonate, dissolving the egg. The fizzing sound you hear and all the bubbles you see in the vinegar are the carbon dioxide produced by this chemical reaction.
