We used starburst candies and toothpicks to model the chemical reaction of photosynthesis. We made 6 Carbon dioxide molecules and 6 Water molecules following the rules for chemical bonding (4 bonds for Carbon, 2 bonds for Oxygen, 1 bond for Hydrogen). Then we rearranged the atoms to make one Glucose molecule (C6H12O6) and 6 Oxygen molecules. We went over the formula for photosynthesis and used our reading as a guide for building the molecules. Check out the worksheet that we used: Photosynthesis. I will be at a teacher workshop all day Thursday and Tonie Lilley will be my sub for the day. We will be looking at population dynamics on Thursday.
