Dinosaur Science


Cookie Paleontologist Materials needed: chips-a-hoy chocolate chip cookies, toothpicks

Children pretend they are paleontologists while picking at and scraping out the chocolate chips in the cookie – much like digging the bones out of the dirt.


I’ve purchased dog biscuits in various sizes. The first day I have the children paint them white. The following day before school I take them to the sand box and bury them. We head outside first thing and dig up our bones. We carefully transport our finds into the classroom where teams work together to put their bones together. I have them glue their bones on large pieces of cardboard. Label the type of dinosaur for them. Of course as always happens we have to be flexible as teachers. On year it snowed the morning of our dig, do you know that many dinosaur bones are found when basements are dug. Our schools basement became the new dig site!


Mix 5 measures of sand (utility sand works great!) with 2 measures of plaster of Paris. Stir together. Add 2 measures of water. It doesn’t matter what the “measure” amount is as long as it is the same for all three. Stir together until mixed. Pour into molds (such as 8oz. paper cups) Push small plastic (Cheap) dinosaurs into mixer immediately. Let dry overnight. Pop out of cups and give to children along with tongue depressors for digging. My young 3’s loved this activity so much that we had to do it twice last year. If possible do this outside as it does create a mess in the process of opening the “egg”. Be sure to look for the fossil too!

We find a true measurement of a dinosaur feet print. We ask the children to guess how many of our feet prints would it take to fill up the dinosaurs foot print. Then we would trace the children foot and place them in the dinosaurs foot print.
