2) Place cups under a light source.

3) Water daily with each type of water (provided by your teacher)

4) Measure plant growth over 2 weeks and record any other observations

5) Construct a data table

Lab Report

At the end of the 2 weeks, compile your data and submit a report that answers the experimental question. The lab report should include each of the following

1) Introduction

- Write the experimental question

- State your hypothesis

- Identify the independent and dependent variables

2) Material and Methods

- Describe your experimental set-up

- Optional (include sketches or photos)

3) Results

- Display a table showing growth over the 2 week period

- Create a graph from your data on Google Sheets

4) Conclusion

- Answer the experimenta questions

- Indicate whether your reject or support the hypothesis

- Summarize the data to support your claim

- Provide REASONING for the results you obtained
