righttopSNC1D Photosynthesis Lab Go to and open the “Photosynthesis Lab”.Your task will be to determine the optimal light intensity and colour for photosynthesis. Write your purpose in your own words.Write a hypothesis (what you think the optimal level and colour will be).First explore the Gizmo (check out the various tabs at the top of the page). Figure out how to change the light intensity and colour. Figure out how you can tell what the photosynthesis rate is. Write a list of materials in point form (NOT computer, but what’s seen on the screen).Write a method for your experiment. Be sure to outline separate methods for the intensity and colour, describing your dependent, independent, and constant variables for each.Carry out your experiment.Record your observations by taking a “photo” of the graphs produced.Answer the following questions for your analysis:Describe the effect of light intensity on the rate of photosynthesis.How would this affect your choice of light bulb wattage if you were a greenhouse owner in a low light area and why?Describe the effect of the colour of light on the rate of photosynthesis. How could this knowledge affect your choice of light bulbs if you were a greenhouse owner in a low light area? Write a conclusion (response to your purpose).Your formative lab (for feedback on what to fix) will be due on ____________________.Your final summative lab (counts for marks) will be due on ____________________.Photosynthesis Lab Name:______________________________Your mark will be based on the following rubric:INQMethod for light intensity and colour exploration is clearly, completely, and logically explained using numbered plete observations are included for both parts in some type of chart form (i.e. graph, table…)./ 5/ 5APPAnalysis answers for # 1 & 2.Analysis answers for # 3 & 4./ 5/ 5Comm.Purpose & Hypothesis are clearly stated.Materials are all listed in point form.No personal pronouns are used.No spelling /grammar errors.This rubric is copied onto the bottom of your work / 1/ 1/ 1/ 1/1*Note that 5% is deducted for each day if the lab is submitted late.*Note that 1 Communication mark is lost if your work is not in your science folder. ................
