Did you know that you can make your own dinosaur dig excavation activity? All you need is two household ingredients and a few sunny days. It couldn’t be easier!
Evan loves dinosaurs. He has loved them for over 2 years now and there are no signs of his interest fading. Last fall, I did this neat dinosaur fossil excavation activity with him and made these dinosaur dig fossil puzzles, but I wanted to make an even more realistic dinosaur dig for him.
I knew that oobleck (or goop) could be left out in the sun to dry and it would harden up, so I thought it would be cool to put our dinosaur fossil skeletons in some oobleck and leave it out in the sun to dry. I love that this homemade dinosaur excavation kit is so easy to make!

Setting Up the Dinosaur Fossil Excavation
1. Mix up some oobleck by combining cornstarch and water. I am not giving exact measurements because it will depend on the size of the container you are using and how much cornstarch you have on hand. You will want to use approximately twice as much cornstarch as water. So if you use 2 cups of cornstarch, you will use 1 cup of water. If it is too soupy, add more constarch. If it is too thick, add more water.
2. Put the dinosaurs into the oobleck. You will want to push them down as much as possible to so that they are buried.
3. Put outside in the sun and leave it for a day or two. It rained, so I had to bring mine in and then put it back out, so I ended up waiting about 2.5 days. You will know when it is ready because it will get very hard and it will start to crack all over the surface. I actually think mine wasn’t as dry as it could be. There was rain and lots of humidity and the temps weren’t as high as I hoped. I plan to do this again when we have a few days of hot and sunny weather.
Digging for Dinosaur Bones Activity
Grab your toy tools, paintbrushes, toothbrushes or any other tools you think could be used to dig out the dinosaurs. Put them next to the dinosaur excavation container and invite your child to dig out all of the dinosaurs.
Evan was super excited and began using the hammer to break apart the hardened oobleck. Once he was able to remove the first dinosaur skeleton, he used the paintbrush to dust it off. Then he got to work digging out the second dinosaur fossil.
After he dug out both dinosaurs, he had a lot of fun playing with the remaining chunks of the hardened cornstarch mixture. He crumbled them in his hands and hit them with the tools. He even put the dinosaurs on them and pretended they were huge boulders.
This simple homemade dinosaur excavation kit is well worth the 5 minute prep involved and so much more! We will definitely do it again this summer!
