Lesson for the New National Science Curriculum 2014. Includes an activity on Euglena. Place information sheets around the room and get students to label organelles and describe function of each organelle on their task sheet. Time them at each information sheet for 2 minutes and get them to move onto the next sheet around the room with the sound of a bell. Although there is a lot of information on each of the information sheets, students need to read all of it / sift through it and pick out the function/job/purpose of the organelle. This is a skill to be learnt in itself.
