See attached PDF.

In this lab we will apply the principles of diffusion, osmosis, cohesion and adhesion to movement of water within plants, study transpiration in the transport of water within plants, understand how differences in water potential affect transport throughout the plant, and study the affect of plant environment on transpiration rates.

Prior to Lab Day:

Review the attached PDF to familiarize yourself with the general idea of the lab.

Read page 4-5 for background information on HOW the experiment works.

We will be doing investigation I only, using room, light and fan conditions.

Lab Day:

1. You will work in assigned lab groups.

2. Before you begin, discuss hypotheses with your group and agree on a best hypothesis.

3. Execute the procedure on pages 7-9 of the handout.

4. Share data, record class data.

5. Clean up.

6. When finished, immediately begin writing up a formal lab report in your actual lab notebook of what you did.

a. Title and date

b. Problem: How do environmental factors affect transpiration rates in plants?

c. Hypothesis: See page 6 of the handout and adjust it to reflect the conditions tested in the lab.

d. Experimental Design: brief description of investigation 1 and the conditions tested. sketch of set-up included here or in procedure.

e. Materials: list the items used in the lab.

f. Procedure: Give a summary of the procedure and set up.

g. Data collection: tables, recorded observations, etc. for your individual group and the class.

h. Analysis: graphs and comments.

i. Conclusion: discussion of your observations and results, what it means, relate to the provided background information.

j. Post-lab: study questions on page 12 of the handout.

7. Turn your in lab notebook by the assigned date for review by Dr. Kostenko.
