This lab is one I use in my biology class. I like it because it requires the students to engage in inquiry and research. They are given 3 questions to choose from, they research and make a choice. Then the real fun begins, students then have to design and execute an experiment, using only the supplies provided by the teacher. After they finish they have to complete a lab analysis packet (much easier to grade then lab reports, equal in complexity and rigor). This listing includes a full materials list, the worksheet packet and a set of teacher tips, hints, and instructions for a successful lab day. I find that this activity really enhances engagement, and has dramatically increased my student's understanding of the topic of photosynthesis.
