Comments about Including the Performance Expectation
The overall sequence of these activities is good, but more teacher needs to make sure to allow the activities to be student-centered. Discussion questions need to be purposeful and have students focus on the objectives of the PE. This activity has students analyze and interpret data about ecosystems. The students use this data and information to determine what would happen if part of the system were to change. If the teacher wishes to cover the SEP, Engaging in argument from evidence, the students need to develop a relevant question to elicit the depth of response needed for a strong argument.
