At the end of this unit
in terms of scientific enquiry
most pupils will: identify variables relevant to an investigation of photosynthesis and suggest how these might be controlled; make observations and measurements using an appropriate technique, and use measurements to produce a graph; explain patterns in graphs using scientific knowledge and understanding
some pupils will not have made so much progress and will: suggest how to control variables identified for them in an investigation of photosynthesis, making appropriate observations and measurements and producing a graph
some pupils will have progressed further and will:
relate findings about the production of oxygen in photosynthesis to wider environmental issues,
eg seasonal changes
in terms of life processes and living things
most pupils will: identify carbon dioxide from the air and water as the raw materials, and light as the energy source, for photosynthesis; explain photosynthesis as the source of biomass and represent photosynthesis by a word equation; describe how leaves are adapted for photosynthesis and how roots are adapted to take in water; distinguish between photosynthesis and respiration in plants
some pupils will not have made so much progress and will: identify carbon dioxide from the air and water as the raw materials for photosynthesis; recognise that plants take in water through their roots and that photosynthesis takes place in leaves
some pupils will have progressed further and will: describe how cells in the leaf and root are adapted for photosynthesis and for taking in water; represent photosynthesis as a symbol equation; describe the relationship between photosynthesis and respiration in plants
