Now have a look at the demonstration of Elodea!
• Try and answer the following questions as you are given the demonstration
• What are the effects of changing:1) Carbon dioxide concentration2) Temperature3) Light intensity
Be able to give a scientific explanation for each of these factors as well!

Group activity!
Can you make a poster summarising the effect of changing – Light intensity– Carbon dioxide concentration– Temperature
Your poster must include a sketch graph for each three factors and an explanation of why they affect the rate of photosynthesis!
