I love this project – I do this every so often for my kids and they just always think it is so much fun! It involves making your own dinosaur “fossils” with small toys and Plaster of Paris
- Mix up the Plaster of Paris according to instructions
- Place your mold onto a solid surface
- Pour a little of the plaster mix into the mold
- Add your mini dinosaur into the mix
- Top up with plaster and leave to harden as per instructions
- Give your little one a few tools and let them get excavating!
To make this an economical project I bought a HUGE 20kg bag of Plaster of Paris from my local builders merchant for about $20 – which was a great buy seeing as it was $13 for 500g at the craft store…
You can of course use anything as a mold (yogurt pots, ice cream containers) and below you can see a series of pictures showing how you can make a really big one in your sandpit!
Here is how I made a BIG fossil in the sandpit which took the kids days to excavate!
- Dig a hole in the sandpit
- Pour in your plaster of paris and throw in your plastic dinos
- Cover with sand
- Drag a spade or stick through the mix to make a cool shape
- Leave to dry (3 hours I think..)
- Let the kids loose with a hammer and some paleontologist protective eye goggles -cheap safety glasses!
These little molds are so neat with their dino shapes – I think they are for muffins. I made these crayons below using a tutorial I showed here.
Let me know if you give this a try! Goes without saying this is something you need to make and get the kids to play with OUTSIDE!!
