In this lesson, students will design their own controlled experiment. The teacher introduces osmosis through a short Prezi, checking their understanding along the way by means of comprehension questions included in the presentation. Immediately after the introduction, the teacher will place students into three or four groups and facilitate a brainstorming process in which students work together to develop questions, list materials and outline procedures. These will then be peer reviewed by their classmates in which they will give them recommendations and or offer suggestions. The teacher will make the final approval and experiments will commence the following class. Students will then report their results as a written lab report or using the same lab report format to create a gallery walk.
