The effect of light intensity on photosynthesis in Elodea
• Plan
• - method
• Independent variable – distance from light source
• Dependent variable- number of bubbles produced every minute
Control
• Amount of elodea
• Amount of water
• Type of light source
• Amount of ambient light
Method
• Diagram
• Simple step by step explanation of the task
• How often will you carry out this task
• Why?
Prediction
• I think that the plant will _______________ if it comes closer to the light
• I think this because__________________________________________________________________________________________________________________________________
Results table
• Remember to include units
• The independent variable will be on the left and the dependent variable on the right
Graph
• X = independent variable
• Y = dependent variable
• Lines of best
• Don’t forget a title and units on the axis
Conclusion
• My results show that
• My graph shows that
• This proves/ disapproves my prediction because ______________________________________________________________________________________________________
evaluation
• How could you improve your investigation?
• How could you make it more reliable
• Have you identified any anomalous results
