NGSS Performance Expectations

This lesson helps students start thinking about all of the unit NGSS Performance Expectations but does not feature a mastery of any of them.

Three-dimensional Learning Progression

The pretest and discussion in this lesson (a) help students to anticipate and begin thinking about the questions that they will answer in this lesson and (b) help you as a teacher see how your student reason about how matter and energy are transformed when animals eat, grow, move, and breathe (digestion, biosynthesis, and cellular respiration). In the Application Activity Sequence, both activity 1.1 and activity 1.2 in this lesson serve as the “Establish the Problem” phase for all the activities in the Animals unit.
