[2] Materials: Cameras (Good use for cell phones in the classroom). List of different types of symmetry. Computers to upload photos. Take students outside and get them to observe different things in nature that have radial symmetry, lines of symmetry (horizontal, vertical and diagonal) and are asymmetric. Students can use camera’s to take photos of their findings instead of picking grasses, flowers, bugs, or anything out of nature. This way they are leaving no trace. Remind the students why they are taking photos rather than collecting things out of nature. Have a class discussion 10 minutes before the class is done and ask the students to expand on what they found. Did all the flowers they found, rotationally symmetric? What items were asymmetric? Why might this be? Get students to look deeper into the ideas behind symmetry. The next class, get the students to upload their photos onto the computer. Using any photoshop program, get the students to draw the lines of symmetry on their digital photo. Get them to record how many lines of symmetry are on each shape. Students will draw all the lines on all of the photos they have taken. The teacher can either use this as an assessment or as a learning tool. [Nine]
