Beginning 2. Developing 3. Proficient 4. Expanding I can identify parts of the process of photosynthesis in connection to  the needs of living things. I can use evidence to explain the role of photosynthesis in the cycling of matter or the flow of energy in and out of organisms I can use valid and reliable evidence to explain the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms. I can extend my explanation of photosynthesis to predict the effects on the cycling of matter and flow of energy when a variable is changed.
