Rate of photosynthesis
Rate of photosynthesis
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!
What happens when we change these factors?

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!
Copy and complete the following sentences based on your OVERALL understanding of the photosynthesis topic so far...
• Something I have enjoyed learning is...
• Something I find difficult is...
• An example of an exam question could be...
YAAAAY!! We´ve finished photosynthesis!
