Question;Plant Transpiration;Unit VIII;Assessment;Introduction;If you have;not already, you or someone you know will try to grow avariety;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;haveabout plants. In this activity, you will have a chance to manipulate different;variables tosee 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:;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.;Type;all answers directly on the data sheet.;Select;Save As, and use your last name and student ID as a file name.;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 of20;points.;1.;What;are the three different variables that you tested?;2.;State;your question.;3.;State;your hypothesis.;4.;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?;6.;Did;any of the environmental factors (heat, light, or wind) increase the;transpiration rate more than the others? Why?;7.;Which;species of plants that you tested had the highest transpiration rates? Why do;you think different species of plants transpire at different rates?;8.;What;is your conclusion?;9.;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.;Results;Table 10 points;***You should include data for 8 different;plants. Make sure you reset the lab (upper right corner) to receive 4 more;plants.***;Question;11 is an extended response question and should be at least 200 words. Total: 20 points;11.;You want to reduce the amount of money that;you are spending at the grocery store. You and your family decide to plant a;small garden to provide a variety of foods. Since you completed the activity;above, you know that plants require certain nutrients in order to survive. Read;the information in the textbook concerning the future of agriculture (pages 586;? 592). What are some methods that you would implement into your garden? What would;you try to avoid?
