Plant Transpiration

Unit VIII Assessment

 

Introduction

 

If you have not already, you or someone you know will try to grow a variety of plants either inside your house or outside in a garden. What type of soil do you need? How often should you water the plants? Should you plant them in full sun? Why do some plants need less water and some more? These are questions that many people have about plants. In this activity, you will have a chance to manipulate different variables to see how much water some plants use and how much some lose through transpiration.

 

Objectives

 

  1. Conduct virtual experiments to determine factors that affect transpiration.
  2. Compare and contrast sustainable and unsustainable farming practices.

Materials

 

Computer with internet access

 

Directions

 

  1. Go to: http://glencoe.mcgraw-hill.com/sites/dl/free/0078695104/383946/BL_10.html
  2. Read the Purpose and Objectives.
  3. Read and follow the information under Procedures and complete the lab for all 4 plants and all 3 variables.
  4. Reset the lab and complete the lab for the next set of 4 plants and 3 variables.
  5. Record your information in the Results Table provided on this sheet.
  6. During and after the lab, answer the questions below.
  1. Type all answers directly on the data sheet.
  2. Select Save As, and use your last name and student ID as a file name. 
  3. Upload the data sheet as a .doc, .docx, or .rtf file when finished.

 

Questions 1 – 10 are short answer questions and should be answered in 2 to 3 words or 1 to 2 complete sentences. Each question is worth 2 points for a total of 20 points.

 

  1. What are the three different variables that you tested?

 

 

  1. State your question.

 

 

  1. State your hypothesis.

 

 

 

 

 

 

  1. Describe the process of transpiration.

 

 

5.   What environmental factors that you tested increased the rate of transpiration? Was the rate of transpiration increased for all plants tested?

 

  1. Did any of the environmental factors (heat, light, or wind) increase the transpiration rate more than the others? Why?

 

  1. Which species of plants that you tested had the highest transpiration rates? Why do you think different species of plants transpire at different rates?

 

  1. What is your conclusion?

 

 

  1. Did your results support your hypothesis?

 

 

10.  State another question about transpiration that you would like to have answered that you did not answer in this lab.
