My aim is to investigate the rate of photosynthesis from a plant in water Essay Example

My aim is to investigate the rate of photosynthesis from a plant in water Essay Example My aim is to investigate the rate of photosynthesis from a plant in water Essay My aim is to investigate the rate of photosynthesis from a plant in water Essay as I explained earlier in my background knowledge. On my graph of all the results, there are a few obviously different results, but none look like they were that weird. But when I put the separate plants results into separate graphs it showed that all the results were completely different, except for the third one because all the lines, although they were decreasing, they were all decreasing from different amounts of bubbles to another test of the same plant. For example, the third test on the second plant: the number of bubbles at five cms away from the light was 69 whereas the other two were 35 and 32. These weird results will uneven our average, and it isnt a very fair test of accuracy. The only plant that did have the most near results to each other was the third plant, so if we wanted a more fair result we could just average those up but then we wouldnt have much to compare to. If two out of three sets of results are dodgy then this must mean there is something wrong with the way we were doing our experiment. From our averaged graph there is an obvious pattern, the number of bubbles produced by the plant starts of at a high number usually between fifty and sixty and then decreases steadily until it gets to twenty five cms away from the light where then it still decreases but less steeply than before. EVALUATION: Our experiment didnt go to well because although we managed to keep everything under control as much as possible, and we didnt get a huge amount of freak results, it still isnt a very reliable way of testing what we wanted to find out as it is way too basic. If we wanted to use the same method but improve it we could involve more people so that we would be able to check we had counted the bubbles correctly. Also we would need to control the background light as it would interfere with the experiment, but we didnt have the means for it this time. Because of all these problems the strange results we got are very likely to be accuracy problems when counting the bubbles. It isnt a fair test to have one person counting them all because they might not count properly, but a way of solving this is to have a few people counting so that the results would be more exact. The background lighting interferes because it adds to the rate of photosynthesis when we want to be testing from a certain light intensity. We managed to keep the temperature pretty much the same for the whole experiment, it dipped between 23c and 25c, so even though we did as best as we could, if there was a way of keeping a constant level temperature it would make the test a lot more fair. An even better way of improving this experiment would be under properly controlled conditions where we wouldnt need to rely on someone having to count the bubbles, and we could use more reliable tools.

How to Email a Professor About Not Attending Class in 5 Steps

How to Email a Professor About Not Attending Class in 5 Steps Writing an email is not a big deal, right? But writing to your professor is not the same as to your friend. Its important to notify your professor you are going to miss the class for two reasons. First of all, because of the etiquette. Secondly, to let your teacher know that you will catch up the information you missed while you were absent. Below, youll find some useful tips on how to email a professor about not attending class.

Personal preferences or contact/address rules should be followed as closely as possible in order to communicate with proper respect. Check your professors email address in the syllabus or on the website of your institution. If you cant find contact information anywhere, ask a friend to pass along a written note from you. 2 Plan Beforehand If its possible, contact your professor a few days before you are going to miss a class or as soon as you know you wont come. If you missed a class due to the unexpected circumstances, write about the cause of it and apologize. You dont need to write 10 sentences about you being depressed and sorry for skipping a class but its always best to show that you appreciate their work, time and effort. 3 Use Clear and Concise Language Be polite and keep your email laconic. Include only important and necessary information, there is no need to write long and detailed texts. Professors usually receive hundreds of emails so don’t make them waste their time looking for an actual purpose of the message through your long text.

Use their last name and salutation â€Å"Dear† or simply the academic title and last name. For example, â€Å"Dear Professor Green,† â€Å"Dear Dr. Green.† Dont use phrases like  Ã¢â‚¬Å"Hey, Mr. Green.† Body Inform your professor that you won’t be in class and explain the reason in one or two sentences. Let your professor know you will turn your assignments in or attach them to the email. Ask if you can meet your professor to receive the assignments or material you miss. Thank your professor for his time and attention. For example, â€Å"Im sorry in advance†¦Ã¢â‚¬  or â€Å"I apologize for not making into a class†¦Ã¢â‚¬  if you are writing after the day of absence. Complimentary Close End your email with words â€Å"Sincerely† or â€Å"Best regards,† add your full name, your class and section number information one more time. Sample email to your professor about not attending class: Subject: class attendance, [class and section information] Dear Professor X [your professors name], I apologize in advance for not attending your class on Monday, November 6th, because of the doctors appointment at 1.30 P.M. I will turn my assignment in on Tuesday, November 7th, instead. As far as I know from your schedule, your office hours on Tuesday are from 2 to 4 P.M.
