Dinosaur Fossils: Earth Science Activity

| 2 Comments

Creating miniature fossils is a dinosaur activity for kids that is sure to capture the imagination!

Dinosaurs are a great topic to sneak into your earth science fossil unit. They engage your students’ interest easily and often produce the best writing samples of the year. This souvenir activity is a memorable way to wrap up your study and will enrich your students’ learning experience.

The top 5 dinosaurs by popularity: Tyrannosaurus (T-Rex), Diploducus, Velociraptor, Triceratops, and Brontosaurus. Other dinos of interest include: Pterosaur (a flying dinosaur) and Stegosaurus.

Materials: Tupperware (one per student), modelling clay, shells, plastic dinosaurs, plastic plants, Plaster of Paris, water

Directions:

  1. Press a little modelling clay, about 2 cm, into the bottom of a Tupperware container.
  2. Carefully press shell or other object into the clay.
  3. Remove objects from the clay.
  4. Mix a ratio of 1-part water to two parts Plaster of Paris.
  5. Pour the plaster on top of the clay and let it dry for 24 hours.
  6. Remove the plaster from the Tupperware and leftover clay. (If you have students remove all of the plaster pieces from the clay, you may reuse the clay.)

Writing Extension Activities:

Looking for a fun, science-based, writing activity for kids?

Write a short story about a dinosaur fossil. There are all sorts of mysteries about dinosaurs that are waiting to be solved with some research effort and exploration. Include key vocabulary and specific descriptions of the fossilization process. What does the fossil tell you?

  • Research a type of dinosaur.
  • When and where did they live?
  • What did they eat (carnivore, herbivore, omnivore)?
  • What does their name mean?
  • What is the theory of how they died?
