Science 10 Unit C Living Systems 19 Acknowledgments My science 10 students at Forest Lawn High School, Calgary for letting me us their work and photos. Also for the energy they give me to work with new things. Forest Lawn Science teachers for allowing me to bounce ideas off them and encouraging me. Especially Rekha Dhawan for working with my ideas and Dave Margach for making me believe that I could take on this big pilot project successfully. Ms Kiefer and her design class for teaching me how to make my Power Point presentation “whizzy”. Rebecca Michaels, my amazing lab technician, for all her organization, dedication and humour.
