Do you have dinosaur obsessed kids? Have they ever wanted to hatch their own dinosaur? Last week we did just that using a little science, chemistry to be exact. It was so much fun the kids keep begging to do it again. This activity is great for all ages and abilities, even adults get involved in the science fun!
Hatch dinosaur eggs with science.
Last week we hosted a family reunion and as the host I knew I had to come up with some activities to keep the kids entertained. I had all boys from 3 to 10 years old and for a while I struggled to come up with something that would work for everyone.
Finally the answer came to me, hatch dinosaur eggs! And it was a HUGE hit!
Check out our dino egg hatching in this video. The kids went nuts!
All the kids were able to participate. They just need to be old enough to use a medicine syringe without squirting themselves. For the younger guys this was some great fine motor strengthening.
Seeing the chemical reaction was a hit with all ages and even the adults got all excited as we could see bits of our dinosaurs coming out.
My boys especially loved trying to guess what type of dinosaur it was while it was slowly being revealed.
Once hatched the boys gave the dinosaurs a little extra cleaning.
And the colours! Oh it was sooooo beautiful to see how they are swirled together, changing and blending throughout the hatching.
This activity would be great at a party (what a way to get a nice keepsake from the party!), in a classroom, as part of a science experiment or even a dinosaur unit study. So many fun applications. I also think you could create some gorgeous imprint art if you carefully laid some canvas over the bin once the eggs were all hatched.
How to hatch dinosaur eggs
You will need:
Casserole dish or some other container
Vinyl Mini Dinosaurs (72 count)Arm & Hammer Baking Soda – 16 ozWilton Color Right Performance Color System, 601-620010ml Oral Syringe with Cover- 15 Syringes by Care Touch (No needle)MedPride Nitrile Exam Gloves, Powder-Free, Small, Box/100Premium Quality Children’s Safety Glasses
What to do – Chemistry fun with a Dino Twist!
The first step is to colour your baking soda. I found one box of baking soda made approximately 3 eggs, depending on the size of your dinosaur. Simply add your drops of colour and carefully mix. I highly recommend you use gloves. I didn’t the first time and my hands were dyed for two days.
Once the baking soda is coloured carefully added some water. For one box of baking soda I used approximately 1/4 cup of water. Add it slowly and mix thoroughly before adding more. You want it to just start to become paste like so it will stick together.
I liked making multiple batches of different colours so we could make our eggs multiple colours. For some extra fun, hide one colour in the middle with a different colour on the outside. Another trick is to add sparkles or glitter to the middle so they are released during the experiment as your dinosaur is coming out. The combination of new colours, glitter AND a dino baby really gets the kids excited!
Take a palmful of the paste and squish it about to make a ball. Press in a dinosaur. Then add more paste to the top and sides until the entire dinosaur is encased.
Place on parchment paper on a cookie sheet and set in the freezer.
Freezing helps to set the baking soda dinosaur eggs. I actually dropped one after it was frozen and it didn’t break. Perfect for little hands that want to explore the eggs before they start hatching. They freeze very quickly and are ready within an hour, or leave them in overnight.
Ready for Hatching!!
When you are ready for the big hatching, set the baking soda dinosaur eggs in a large dish. I liked using a casserole dish so you could see from all sides, but any dish will work.
Dribble some dish soap on the bottom of the bowl.
Pour some vinegar in a cup or bowl and give the kids each a syringe.
Squirt your baking soda dinosaur eggs to start them hatching!
The reaction is a simple baking soda and vinegar reaction, much like our bottle rockets, but this was a different way to explore that reaction. Plus, it’s fun!
A couple words of caution:
– Wear rubber gloves when making the eggs or you will colour your hands! See my Instagram for proof.
– You may wish to have the kids wear safety glasses depending on their age and competence with the syringe, vinegar in the eyes is not fun.
– If you or any of the kids have hangnails or any cuts to their fingers, consider rubber gloves, that vinegar stings!
– This can be a messy activity! Prepare the area appropriately.
The Science Behind Simple Chemistry Hatching Dino Eggs
This activity explores the popular baking soda and vinegar reaction. During this chemical reaction, the vinegar reactions with the baking soda. Vinegar or Acetic Acid has the chemical formula CH3COOH. Baking soda is a base also known as Sodium Bicarbonate and has the chemical formula NaHCO3. During this reaction the products are sodium acetate (NaC2H3O2). Sodium acetate is made of 1 sodium ion, 2 carbon atoms, 3 hydrogen atoms, and 2 oxygen atoms. The other products are water (H2O) and carbon dioxide (CO2). Carbon dioxide is the gas that causes the bubbling during the reaction.
Taking Dino Eggs Chemistry to the Next Level
Why not use a digital thermometer to test if the reaction is exothermic or endothermic?
Use candy or a chemistry model set to build and demonstrate the chemical reaction that is taking place.
Use canvas placed gently on top of the beautiful resulting liquid to create gorgeous art!
