Last week, my daughter’s school had a dinosaur-themed week, and we carried the fun over to our home! Here’s a roundup of the STEM and speech-focused activities we tried, including homemade printable workbook, a fizzing dinosaur egg experiment, and our favourite printable activities we found online.

2. STEM Dinosaur Hatching Egg activity
Last week my daughter came home with her dinosaur themed homework and asked to make “dinosaur eggs”. I knew exactly what she meant: we had made bicarbonate dinosaur “eggs” over summer in preparation of visiting a paleontology dig.

It’s incredibly simple and requires just 3 household ingredients: bicarbonate of soda, water and vinegar, making it perfect for a rainy afternoon, or for a Saturday morning when you need to keep the kids busy while you take a shower.
Here’s how you can create your own fizzing dinosaur eggs that “hatch” as they dissolve!
What You’ll Need
- Bicarbonate of soda (baking soda)
- Vinegar (any kind—white vinegar, cleaning vinegar, or whatever you have on hand)
- Water
- Optional extras:
- Food colouring: Add some colour to your eggs for extra fun!
- Small toys: Use Kinder egg toys, LEGO characters, or tiny dinosaur figurines to hide inside the eggs for an exciting surprise.
How to Make Dinosaur Eggs
- Prepare the Mixture
- In a bowl, combine bicarbonate of soda and a small amount of water.
- Add water gradually until the mixture is moist enough to mould into an egg shape with your hands. If it’s too wet and breaks apart, simply add more bicarbonate.
- Add Colour and Toys (Optional)
- If you’re using food colouring, mix a few drops into the water before adding it to the bicarbonate.
- Take a small toy (we used those small kinder eggs toys we had already, one was actually a dinosaur, one was a tiny alien) and press the mixture around it, shaping it into an egg.
- Let Them Dry
- Once shaped, let the eggs dry overnight to harden. Place them on a tray or plate to ensure they keep their form.
How to Hatch the Dinosaur Eggs
The fun really begins the next day! Here’s how to make the eggs fizz and reveal the hidden surprise:
- Place the dried eggs on a large plate or shallow dish.
- Drip vinegar onto the eggs using a teaspoon. You can also use a dropper or squeeze bottle for more control.
- Watch as the eggs fizz and dissolve, revealing the hidden toy inside!

4. Extra Dinosaur Activities We Loved
- Hatching baby dinosaur printable. Colouring, and cutting activity. Great for fine motor skills – design by Krokotak Prints
- 3D Mammoth colouring cut out and gluing activity that’s fun to play with.
- 3d diplodocus colouring, cut out and assembly activity. No glue required!
- Hatching pop-up Dinosaur by Fatih Güngör on Canva. We played a game where I or another toy, thinks it’s a normal egg and discover it’s a scary dinosaur. Don’t discount the extent to which imaginative play develops speech! It’s absolutely vital in developing speech.
I download these activities I found online onto my phone either as pdfs or images and send to my wireless printer. In case you were wondering: HP wireless printer: 💯 worth it. HP ink subscription? Absolutely not worth it.
