- What is a fossil?
- What kinds of things can become fossils?
- How do you tell how old a fossil is?
- Where is the best place for a fossil to form?
- How long does it take for a fossil to form?
It is important that you find out what informal ideas your students already
have about fossils before you begin instruction. You can ask them to respond
to the questions above, either in writing or orally. Keep their responses
for later, so that you can compare what they think at the beginning of
your instruction on fossils to what they know at the end.
