Lesson 1 Lab: Photosynthesis



Lesson 1 Lab: PhotosynthesisPurposeIn this lab we will study photosynthesis in a variety of conditions. We will vary light intensity, carbon-dioxide levels, temperature, and the colour (wavelength) of light in order to find out how each factor affects oxygen production. Oxygen production is used to measure the rate of photosynthesis. See the instructions that follow about accessing the Photosynthesis Lab Gizmo to simulate photosynthesis.KEY TERM:limiting factor:?any biotic or abiotic factor that controls or limits the functioning of an organismProblemWhich conditions produce the best rate of photosynthesis?How do?limiting factors?affect the rate of photosynthesis?Part A: Lab ReportYour lab report should be set up in the same format as this template.Review the?Photosynthesis Laboratory Evaluation Rubric (below)?to see how your report will be assessed.Consider the problem and prepare a hypothesis before you open the Photosynthesis Lab Gizmo.Open the?Photosynthesis Lab Gizmo. You may need a LearnAlberta password to access this lab. Contact Ms. Germaine for this information.Click on the “Exploration Guide” button just above the gizmo. Follow the procedure provided.Answer the Observation questions in your lab report as you complete the lab simulation.When you write your conclusion, make sure to answer the questions that were asked from the “Problem” section of the lab. Also state whether or not your hypothesis was correct. Support your answers with specific examples from the lab.If you choose to work with a partner, make sure to indicate both names on your lab report.Photosynthesis Lab Gizmo: B: Gizmo QuestionsOnce you have completed the lab, including your lab report, answer the self-scoring assessment questions found in the gizmo. Check your results. You will receive an individual report of your self-scoring assessment results, and an explanation of the science behind each answer. Select and copy the text from the self-scoring assessment. Paste the text into a word-processing document, and save these results to your online course folder. Be sure to save this assignment as it will be used to complete the unit essay question at the end of Unit A, as well as during Unit C.Photosynthesis Laboratory?Evaluation Rubric0123Hypothesis(X3)Hypothesis is not related to the questions posed in the problem.Hypothesis is related to the questions posed in the problem; however, it does not show that the student comprehends the link between the limiting factors and the rate of photosynthesis (production of O2).Hypothesis is related to the questions posed in the problem; it shows that the student somewhat comprehends the link between the limiting factors and the rate of photosynthesis (production of O2).Hypothesis is related to the questions posed in the problem; the student completely comprehends the link between the limiting factors and the rate of photosynthesis (production of O2).Apply Your Knowledge(X5)The student did not answer the questions.The student partially answered most of the questions.The student fully answered all of the questions, but may still have some misconceptions about this concept.The student fully answered all of the questions and demonstrates a very good grasp of this concept.Discuss Results(X1)The student did not come up with a conclusion.The student partially answered the problem questions or answered most questions incorrectly.The student answered both of the problem questions, but has come to an incorrect conclusion about the links between the limiting factors and the rate of photosynthesis (production of O2).The student answered both of the problem questions and has come to a correct conclusion about the links between the limiting factors and the rate of photosynthesis (production of O2).Going Beyond(X1)The student did not use the limiting factors to explain the rate of photosynthesis in the Arctic.Research sources were not included.The student only used one limiting factor to explain the rate of photosynthesis in the Arctic.The conclusion was partially correct.Research sources were not included.The student used two or three of the limiting factors in his or her explanation of the rate of photosynthesis in the Arctic. The conclusion was partially correct.Research sources were included.The student included all limiting factors in his or her explanation of the rate of photosynthesis in the Arctic.The conclusion was correct.Research sources were included.Score________ / 30 points ................
