Rate of photosynthesis lab report
Name:
Period:
Introduction: (15pts)
Photosynthesis is
Factors that can affect the rate of photosynthesis are
Our question was
Hypothesis: (5 pts) (Your hypothesis MUST be written as an “ If....then” statement that is TESTABLE by
the experiment you performed)
If
then
The dependent variable in our experiment is
The independent variable in our experiment is
The treatment groups are
We controlled the variables by
Materials: (10pts) (Make a list of all materials used)
Procedure: (15 pts) (Make a numbered list of all the steps taken in your experiment. Another person
unfamiliar with this lab should be able to replicate this lab on their own, based on your procedure.)
Results: (20pts)(Your results should be in 2 forms: a data table AND a graph. Label all axes on the graph
(make sure the Independent variable is on the x axis), and give it a descriptive title. Most groups will
have a line graph, but colors labs may want to use a bar graph. Include a KEY so the multiple lines can be
identified by the reader. Include 2-3 sentences to sum up your results in this section)
Conclusion: (25pts) (Your conclusion MUST BE AT THE END OF YOUR REPORT or you will lose points.)
Did the data support or reject your hypothesis?
Explain why, using data from your experiment
How do you interpret your results, based on the factors that affect photosynthesis?
What were some possible experimental errors?
What would you do differently to prevent error?
Attachments: (5 pts) original lab documents: Include your 1st lab “the impact of light intensity on the
rate of photosynthesis”, the 2nd lab “Factors that affect the rate of photosynthesis: lab design pre-lab”,
(stamped) materials list, written Procedures list, and data table. Also include the ”Rate of
photosynthesis data analysis and lab report” paper.
Works Cited: (5 pts) You must include:
Textbook, graphing site for your computer graph, and any other materials you used for research
