Unit Title: Unit 1- Life on a Cellular Level
Big Idea/Theme: Life on a Cellular Level
Timeframe Needed for Completion: 3 weeks (on a 90 min per day block schedule)
Grading Period: 1st Nine Weeks
Understandings: This unit is focused on the cell as the basic component of structure and function in living things. In particular, this
unit focused on basic biochemistry and cell processes. Students will learn about cells and many of the molecules that are involved in
cell function. Specifically, students will gain an understanding of:

role of inquiry in investigating cells
basic macromolecules found in living things, the structures of those molecules and their function in living systems.
the function of those macromolecules within the context of cell structure
the functions of various cell organelles
the maintenance of homeostasis within a cell
the replication of DNA in order to prepare for cell division
sexual and asexual reproduction at the cellular level
how DNA directs the production of proteins within a cell
the effects of mutations on protein production
the relationship of gene regulation, cell specialization, and cell communication
Curriculum Goals/Objectives (to be assessed at the end of the unit/quarter)
