This lesson consists of students being given or picking a body system. The student will research the body system and then create presentations and use screencast to become the teacher. This lesson is great because it makes the students analyze the material for pertinent information that is related to their system. Students will need a computer for this assignment. Rubric is included but can be adjusted to what you think is important. Can be done as a group or individual.
I can also send you some examples if you would like one to show your class.
