<![CDATA[Team 7B Science - Review Questions]]>Wed, 30 May 2012 04:46:39 -0800Weebly<![CDATA[Unit 5 Review Questions]]>Mon, 06 Feb 2012 11:07:10 -0800http://www.7bscience.com/2/post/2012/02/unit-5-review-questions.htmlSince we have adopted a new test format (the reflection exams), review questions tend not to be so helpful. You will be relying on the data you have collected from our in-class activities.

Below is a very simple outline of what we covered in this unit. Some of the information below has yet to be covered. However, we will get to it before we take the exam.

Topics on the reflection exam:
1. Fossils (formation, what is preserved, etc.)
2. Fossil types (carbon film, mold/cast, etc.)
3. Fossil identification
4. Trace fossil: footprint analysis
5. Natural evidence: tree ring analysis
6. Relative age: rock layers
7. General discussion of evidence scientists have collected and what that evidence can tell us (basically, this summarizes our unit). ]]><![CDATA[Unit 4 Review Questions]]>Thu, 12 Jan 2012 07:52:33 -0800http://www.7bscience.com/2/post/2012/01/unit-4-review-questions.htmlYou may print and answer these questions and bring them with you for the quiz on this information.
