Fossils: Doodling and Diggin' the Earth

Time Required: Two 45-60 minute sessions
Skill Level: Advanced
Recommended Grades: 3rd to 5th

Students will work in small groups to design and 3Doodle a cast and mold for a set of trace fossils of a dinosaur's bones. Students will research and record facts about their selected dinosaur on the back of each fossil. After swapping fossil sets with another group, each group will carefully dig out a hidden set of fossils from a sandbox and reassemble this dinosaur's skeleton and recorded information.

Knowledge

Students have
  • Learned how fossils are formed.

  • Learned about different types of fossils including, trace fossils, fossilized bones, petrified fossils and carbon film.

  • Learned about fossil molds and casts.

  • Learned how sediments or minerals fill a mold and form a cast.

  • Had practice using the 3Doodler.

Objectives

Students will
  • Use the 3Doodler to create a set of dinosaur bones in 5-7 individual segments as stamps.

  • Use each stamp to create an imprint of a separate skeleton segment in a piece of clay.

  • Understand that some fossils form when minerals slowly take the place of originally once living matter.

Materials

Students will need
  • 3Doodler (1 per group)

  • Pencils (3-4 per group)

  • Scrap paper (1 per group)

  • White copy paper (1 per group)

  • Air-dry clay (1 lb. per group)

Lesson Plan

Instructions

Step 1

PREPARATION (Optional)
Students will review the listed sites and video to learn more about dinosaur fossils and discoveries.

Step 2

Share the goals. Each small group of 3-4 students will select a dinosaur discovery, design a set of stencils for this dinosaur's bones, 3Doodle over the set of stencils, use the doodled bones as stamps to create an imprint of bones in clay and research and record information about their dinosaur.

Step 3

Model how to create stencils and imprints.

Step 4

Note requirements for research: Write a paragraph about the selected dinosaur; where it was discovered; how its fossils were formed; and any information that scientists were able to infer from examining its fossils, e.g., size, height, eating habits, prey, etc.

Step 5

Flip over fossil pieces and reassemble face side down. Glue one piece of paper on the back of each fossil. Use all pieces to write a paragraph.

Step 6

Arrange fossil pieces like a puzzle, so that information about the dinosaur can be read when the pieces are turned over and reassembled.

Step 7

Place one set of fossils into a sandbox. Have another group dig up the fossils and reassemble them as a dinosaur skeleton. Flip them over to reassemble as information about the dinosaur.

Wrap Up

Students will share their set of trace fossils with another group, who will need to unearth the complete set, reassemble them as a set of trace fossils and then flip them over to reassemble as a related information about dinosaur. Share on Twitter #3DoodlerEDU

Assessment

Review student’s stencils, casts, molds and writing to determine their level of understanding. Review Questions: How did we use the 3Doodler to simulate the process of creating a trace fossil? What types of materials, plants or animals may be creating trace fossils today? How do you think scientists can use fossils to create a model of a dinosaur? What inferences were scientists able to make about your dinosaur based on it fossils? How can scientists use fossils to determine how animals have changed over time?

Possible Extensions

  • Students will deliberately leave out one or two trace fossils from their set. Can the other group determine the type of dinosaur it came from with a limited set? Can they reassemble the researched information and figure out which parts are missing? How is this similar to the task of a paleontologist?
