Unit: Cells (written November 2013)
Key Learning:
Cells are the basic units of structure and function of life. Understanding
how they are organized and work together to perform various functions
(such as obtaining energy and maintaining homeostasis) is essential to
understanding life itself
Instructional Tools:
Unit Essential Question:
What are the characteristics shared by all living things?
How are cells organized to perform the work that they do?
How do cells differentiate into different types?
How do different types of cells work together to maintain homeostasis in
a multicellular organism?
How do cells produce/obtain energy to sustain life?
