Re-Testing Review Packet: Cell Processes
Your child has the opportunity to re-test on Unit 3: Cell Processes. In order to re-test, your child must complete several
steps in order to make sure that they are ready for a re-test.
1. Have a parent sign the original test and show that to their teacher _______
2. Complete this review packet and review it with your teacher _______
3. Re-test by January 14th. _______
*This review packet focuses on each of the main focal points of the unit. Most of the information for this packet can
also be found in your science notebook and/or the textbook, Chapter 4.
*Read Chapter 4 and BEFORE starting this packet!
