Write-ups MUST be in essay format. Reports in bulleted or outline format will not be accepted.
Introduction
Background- watch your 2 page limit!- more words may not equal a better grade
How does transpiration work?
Why are adhesion and cohesion important properties of water?
How is evaporation linked to transpiration?
Question- what factors affect transpiration?
Hypothesis- Factors that increase evaporation will increase transpirationPrediction-
Light and wind combined will result in the highest rate of transpiration.
cite sources used- will be graded in literature cited section
- beware of plagiarism - do NOT directly copy information without citing o Please limit the number and length of direct quotes - use your own words and phrasing
- The department attitude on plagiarism is that we are here to educate students first and foremost so... We tell you what plagiarism is before this report, grade the report and indicate any problems with a "see me", then explain explicitly what is the problem in a face to face meeting. You will lose points for plagiarized material that is not correctly cited. If large sections or the entire paper is plagiarized, you will face the consequences of academic dishonesty. Both the person who copied the work AND the person the work was copied from will have consequences.
Methods - TAKE NOTES BEFORE YOU LEAVE LAB
- lab manual citation for method - DO NOT rewrite entire protocol
- details/ changes/ modifications in protocol - yes or no?
Results
- Brief paragraph (see Appendix A)
- watch for students straying into a discussion
- in this report, the paragraph might include info on eliminating air bubbles
- data table (all columns on page 39-40) and graph (include title and label axes) does not count as part of 2 pg limit
Discussion/Conclusion
- most important section
- do each section separately
- Restate question, hypothesis and prediction
- Answer the question
- MUST use their results to answer the questions
- Control
o Why do you have to do a control?
o What is the rate of transpiration for the control (use your data)
- Light only
o How does light increase transpiration?
o What is the rate of transpiration for light only (use your data)
o Do your results reflect an increase? Why or why not?
o Did/ Would heat from the light bulb alter your results? Why did or might this happen?
- Wind Only
o How does wind increase transpiration?
o What is the rate of transpiration for wind only (use your data)
o Do your results reflect an increase? Why or why not?
o Did/Would heavy wind alter your results? Why did or might this happen?
- Wind and Light Combines
o What is the rate of transpiration for wind only (use your data)
o Do your results reflect an increase? Why or why not?
o Was this the highest rate of transpiration? Use your data to demonstrate.
o Why is this the expected highest rate?
- Name and discuss 3 other factors that could be investigated using this same technique/apparatus.
- Weaknesses
- Problems- difficult to measure, problems with potometer.
