Photosynthesis Report

On two A4 papers, write a report on your seed experiment.

Your report must follow the following format:

1. Title
2. Aim
3. Controlled variables
- What you will keep the same
- At least 4 variables
4. Independent variable
5. Dependent variable
6. Plan
- Set of instructions in present tense
- Must include diagrams
7. Results
- Must be in a table
8. Conclusion
9. Discussion
- Link any science ideas to your conclusion

You can type or hand- write your report.

This report is due at the end of the first week of term 2
