Stir, bake, cool and ROAR!

Explore the kitchen while you travel through time to the dinosaur age! There are many steps here to keep the kiddos busy as they prepare their fossils and wait for them to finish baking. Start off by having your kiddo measure out all of the ingredients and mix them together, which will then be used to create dinosaur footprint shapes. Bake the mixture in the oven, wait for them to cool, and then use these fossils for lots of imaginative play opportunities!

📚 Books to explore: Dinosaur Dance! by Sandra Boynton, Oh Say Can You Say Di-no-saur? by Bonnie Worth, and Dinosaurs Love Underpants by Claire Freedman.

Patience, patience. Children will develop their self-regulation skills by waiting for the mixture to bake and cool before they can play with it.

🐕 Make some friends. This activity works great with any type of animal, so feel free to get creative!


For this activity you will need:

1 cup used coffee grounds

1/2 cup cold coffee

1/2 cup salt

1 cup flour

Cookie tray

Plastic dinosaurs (or other animals)

Learning Outcomes






Maintaining attention for increasing periods of time


Step 1:

Help your child mix the coffee grounds, coffee, salt, and flour together in a mixing bowl.

Step 2:

Take a small handful of the mixture and place it on a cookie sheet and press down into a flat, circular shape about ½” thick. Repeat until all of the mixture is used or you have run out of room on your sheet.

Step 3:

Use the plastic dinosaurs to make imprints of feet into the mixtures, using 1 dinosaur per circle. Alternatively, you can use different animals or even leaves from outside.

Step 4:

Place your cookie sheet in the oven at 200 degrees fahrenheit for 30 minutes.

Step 5:

Once finished baking, take the cookie sheet out of the oven and use a spatula to remove the fossils from the sheet. When cooled, flip them over and set them out overnight to let the bottoms dry.

 ⬆️ For older kiddos: Challenge older kids to match the footprints to the plastic animals that they came from.

⬇️ For younger kiddos: Use items that are easier to identify like their hands or leaves from outside.
