QUICKLY mold a base for your “fossil”.
4. After molding a base, place your hand into the base.

with string or ribbon.
While you wait for the fossil to harden:
1. Wash your container in the sink located at the teacher desk.

broom and clean the immediate area.
Day 2 and 3
When you arrive to class, the fossil should be ready for the
finishing touches.
1. You can use the paper to gently smooth the edges.
2. You may decide to paint your fossil.
3. Be sure you open the paint carefully and be prepared to
clean your area before the bell.
4. At the end of class, please clean all paint brushes in the
buckets provided or if there is a sink, use the sink.
5. Return all items used to their appropriate place- CLEAN.
Your completed fossil now needs a story to go with it. Using the
graphic organizer provided, write an outline describing who found
your fossil, where it was found, the year it was found, and how the
scientists decided what it was.
If time allows, begin your story.
