Methods and Materials: →Prepare the Yeast In preparation for the yeast, two table spoons of yeast were measured out onto a piece of filter paper. The yeast was transferred to an Erlenmeyer flask and 200mL of warm water was added to the flask. The contents within the flask were stirred with a stirring rod until all the yeast had been dissolved. →Prepare the Flasks Using a graduated cylinder, 20mL of 5% sucrose was measured out with a plastic pipette and the glucose was placed into a single fermentation flask. 20mL of glucose was then measured out and added to six of the eight fermentation flasks. The remaining two flasks were filled with 20mL of water. 20mL of yeast was measured from the Erlenmeyer flask with a graduated cylinder and this step had been repeated until all eight flasks contained 20mL of yeast. Using paper towels to cover the hole of the fermentation flask, each flask was inverted until the solution was mixed entirely, leaving no air bubble at the to p. →Change the Temperature Two of the glucose flasks were placed in an incubator at 35 degrees Celsius, two different glucose flasks were placed in a freezer at 5 degrees Celsius, and the remaining two glucose flasks remained at room temperature, as well as the two flasks contained with only water and yeast. Each flask remained in each environment for thirty minutes having used a stop watch. →Measure the COâ‚‚ Bubble and Record Data Once the 30 minutes was up, the flasks were marked with a marker at the point where the bottom of the COâ‚‚ bubble ended, and then the flasks were taken out of the incubator and freezer. Once everything was on the table, a ruler was used to measure the length of the COâ‚‚ bubble, made by the marker, and then the information was recorded to a date table. Results: In this experiment Co2 was produced from the breaking down of sucrose from the enzymes in the yeast to create ATP. The temperature of the environments were at three different states ( 27 degrees Celsius, 5 degrees Celsius, and 35 degrees Celsius) in order to track if fermentation occurred at a faster, slower, or normal rate as before. Measured from the top of the CO2 bubble to the bottom of the CO2 bubble, the two flasks in the 27⠁ ° C environment measured: 9.2cm and 10.9cm, the two flasks in the 35⠁ °C environment measured: 12.2cm and 11.5cm, and the two flasks in the 5⠁ ° C environment measured: .6cm and .9cm, and the two flasks in the 27⠁ ° C environment with water did not produce a CO2 bubble. Table 1: Results of Co2 emissions. Figure 1: Figure Legend: This figure shows the size of CO2 bubble emissions in centimeters in each temperature environment. Discussion: In order to successfully figure out the CO2 production of yeast and sucrose, the temperatures of the three environments were changed in order to see that the CO2 production stops, increases or slows the rate it is produced. "Temperature changes have profound effects upon living things. Enzyme-catalyzed reactions are especially sensitive

What Is an AP Scholar Advantages and Requirements

What Is an AP Scholar Advantages and Requirements SAT / ACT Prep Online Guides and Tips You might think the term â€Å"AP Scholar† just refers to anyone who takes studying for AP exams really seriously. But it’s actually an awards program offered by the College Board.In this article, I’ll go over what an AP Scholar is, what you need to achieve to become one, what it means to be one, and some tips on getting the award if it’s something you’re interested in. What Is an AP Scholar? An AP Scholar is, broadly speaking, someone who has received an award from the College Board for doing well on several AP exams. There are several award levels according to how many exams the student scored highly on, as well as their average AP score. What Does It Mean to Be an AP Scholar? If you have an AP Scholar award, you can list it on resumes and college applications. It will signal that you did well on multiple AP exams. The designation will appear on your official AP exam scores, and you will receive a certificate in the mail the September following the time you receive the designation. Sadly, you do not get any money from this award, but it’s nice to have recognition of all your hard work!Of course, the higher-up your designation, the more impressive it is. Gold star for you! AP Scholar Awards and How You Earn Them What â€Å"level† of award you are offered generally depends on three criteria: How many AP exams you have gotten a score of 3 or higher on. Your average AP exam score. Where your high school is located. You can receive the next â€Å"level† of award in subsequent years as you take more AP exams.In this table, I’ll lay out all the criteria for the different AP Scholar award tiers- the AP Scholar requirements, if you will. AP Scholar Requirements Award Designation School Location Requirements Score/Number Requirements Required Average AP Score on all APs taken AP Scholar (none) 3 or better on 3+ AP exams (n/a) AP Scholar with Honor (none) 3 or better on 4+ AP exams 3.25 AP Scholar with Distinction (none) 3 or better on 5+ AP exams 3.5 National AP Scholar United States 4 or better on 8+ AP exams 4 National AP Scholar (Canada) Canada 4 or better on 5+ AP exams 4 National AP Scholar (Bermuda) Bermuda 4 or better on 5+ AP exams 4 State AP Scholar (granted to 1 male and 1 female student per state) Each US state Greatest number of exams with scores of 3 or higher in the state Highest average of those who took the greatest number of exams with scores 3+ DoDEA AP Scholar (granted to 1 male and 1 female student) DoDEA(Department of Defense Education Activity) school students Greatest number of exams with scores of 3 or higher in DoDEA schools Highest average of those who took the greatest number of exams with scores 3+ International AP Scholar (granted to 1 male and 1 female student) Attends school outside US or Canada that is not DoDEA school Greatest number of exams with scores of 3 or higher in international schools Highest average of those who took the greatest number of exams with scores 3+ Step one to becoming an AP Scholar: pick your books off the floor. How to Becomean AP Scholar If you want to be an AP Scholar, at the most basic level you need to take AP exams! You also need to make an effort to score a 3 or higher on every exam you take, not just the minimum number for the Scholar designation you’re going for since lower scores will bring your average down and limit your ability to meet the score average requirements to be an AP Scholar. If you want to meet a certain level before you apply to college, you’ll need to take the requisite AP exams by the end of your junior year, so that you’ll get the award by your senior fall. However, my recommendation would be not to stress too much about the AP Scholar program. For one thing, when you get to the highest levels of the award, whether you get the award or not is somewhat outside of your control, since you can’t control how many AP exams other people take or what their average score is. If you get an AP Scholar award, great! But colleges will be able to see your complete AP score report either way, and they know which APs and AP courses are most challenging. It’s better to take a rigorous course of study and not quite qualify for the next Scholar level than to front-load with content-light APs to get the award. This strange baby-man is actually a National AP Scholar. Key Takeaways The AP Scholar awards are a series of awards given by the College Board for students who have gotten high scores on a number of AP exams. There are different â€Å"levels† of the award depending on the number of AP exams a student has gotten a high score on, their average AP exam score, and where they go to school. If you want to be an AP Scholar, you’ll need to take AP classes and be sure to do well on your exams! However, I don’t recommend stressing too much about these awards - your time is better spent on other projects that will be more impressive to colleges. What's Next?
