The style and grade value depends on the subject. I could find the following: "The internal assessment requirements at SL and at HL are the same." Subject then proceeded to do jumping jacks for 30 seconds. Usually, ATP is created aerobically, with the presence of O2. Have a test subject perform 50 finger lifts with the index finger of their left hand while another person times them. The rates also correspond to an inclination for faster action at higher temperatures. This video shows you how to present your processed data in a clear graph that meets the requirements for IB Biology. Lifts need to remain the same difficulty throughout the lab. Temperatures with a higher slope signify that more time was required to complete the finger lifts, thus showing a build-up of fatigue in the muscles. An arbitrary method of just counting by listening to when the finger hit the table was used, however I admit that I may have missed a few, or accidentally added a few – human error. IB Biology Notes; Option A: Neurobiology (and Behaviour) HL Biology IA (23/24) Biology Extended Essay (31/36 – A) IB Chemistry. Search this site.

Teachers can provide details of useful resources, for example: websites, books, videos, journals or teaching ideas. How does this speak to muscle fatigue onset? Perhaps comparisons of age, gender, altitude, or any other constant variables for this experiment would be worthwhile. Learn more about the IB DP! Report a policy violation. ( Log Out /  There should be 5 lines – one for each external environment temperature. Another weakness was the method of counting the number of finger lifts. Because muscle endurance and ability is so variable between humans, and even within the same human, this lab cannot really generalize for a whole population. Person – 17-year-old female: Different people have different finger endurances, thus not keeping the person performing the finger lifts constant would skew results. Biology Internal Assessment Purpose My interest in the ripening of fruit developed from an Materials – Ruler, index finger of the left hand of a 17-year-old female, water, heat source for water, ice, thermometer (°C), stopwatch, towel, calculator. a. Timer must record time every 10 finger lifts until the test subject has reached 50, at which time would be considered the “total time”. Standard deviation can be calculated as b. Standard deviation can be calculated as b. Plug in the standard deviation into the following equation for standard error, where n is the number of observations/trials: 3. Resources for Data Coming Out of Sarka Park. Because of this, I would suggest a method in which a computer records the cumber of finger taps performed. What happens if you can't do an exam cause ur sick? Remove hand from water bath, dry with a towel, and repeat steps 2-3. Biology Internal Assessment Purpose My interest in the ripening of fruit developed from an Type of finger – index: different fingers have different strengths and thus different finger endurances.

I am less sure about Physics and ESS because I don’t take these subjects. Biology guide First assessment 2016. Factors Affecting Muscle Fatigue: The Effect of External Temperature on the Rate of Index Finger Lifts Background Information: Muscle fatigue has many factors that come into play. Conversely, the slopes of the lines, which signified the change in time divided by 50, decreased as the temperature increased, a negative relationship, also supporting the hypothesis – a higher slope indicates slower activity, implying less endurance, implying an earlier onset of muscle fatigue. I scored a 6 in this class just a few marks below a 7 and my IA was a strong component of my score. As a matter of fact, there are numerous limitations and weaknesses in the design of the investigation. Uncertainty of a Spectronic 20. I just think that iB markers might take orgo molecules as a little bit of a cop-out because there’s a sample IA of that kind already online. These IB DP subject briefs illustrate four key course components. Remember to record data every set of 10 finger lifts. Anaerobic metabolism produces lactic acid as a byproduct. Less oxygen is available to tissue in areas like this, thus inhibiting adequate muscle function, and inducing an onset of muscle fatigue earlier than when there are warmer temperatures because of less ATP to the muscles which inhibits the myosin heads to release from the actin fiber. Place hand in water bath for 5 minutes, to allow the hand’s muscles, blood vessels, and skin to adjust. IB. The interval is created from the highest and lowest values with the uncertainty calculated in for the total time. Within each topic listed below, we include the basic reasons for investigating each topic, what the possible independent variables and dependent variables are as well as the basic experimental setup!

Therefore, it’s super important that your IB Biology IA gets as high a mark as possible. b. IB Biology. English A1; Languages B/A2. Higher rates signified more activity, indicating a higher level of endurance and ultimately a later onset of muscle fatigue. IB Biology. Untitled. 1. Home ; AP & IB Biology ; IB Biology ; 2016 - 2022 IB Biology Curriculum ; Topic 1: Molecules of Life. In … It is the unmodified student work. Lower temperatures such as 0 and 10 seem to have higher slopes of their lines meaning that muscle fatigue onset quicker than in lower slopes. Don’t worry, we’ve all been there. . This project is known as an internal assessment (IA). Hopefully it'll be a decent exemplar for you all. It is known that as temperature dips below desired levels the body restricts blood to the extremities, as their blood vessels constrict. Change ), You are commenting using your Facebook account. Biology guide First assessment 2016. 3 Calcium, Ca2+, however, does affect muscle fatigue. Sometimes, in extreme cases, blood flow is reduced to a very minimal level to the body’s extremities, such as the hands, to save the body’s core systems. Height of lift – 5cm: Not lifting high enough would give an underestimate of the time, while lifting too high would give an overestimate of time. I would recommend starting with the investigation_#_e.pdf. This is my IB Biology Higher Level Internal Assessment. The International Baccalaureate aims to develop inquiring, knowledgeable and caring young people who ... Teachers can provide details of useful resources, for example: websites, books, videos, journals or teaching ideas. Calculate the rate of finger lifts by dividing 50 lifts by the average total time for each temperature setting after adding and subtracting the uncertainty. They need to perform a thorough investigation on a … It has been checked through plagiarism sites already so it will not work. Thermoregulation acts when the body is in undesirably low temperatures, senses by receptors on the skin. Sample questions International Baccalaureate Diploma Programme Subject Brief Sciences: Biology—Standard level First assessments 2016 – Last assessments 2022 Altitude of action – Oxygen amounts inhaled must remain constant, and changing altitudes during the lab would skew the data. Example IA's . ... IB Biology SL Examination 2016”. Change ), You are commenting using your Google account. Fixing this would entail placing a platform at the specific height of the desired lift, and requiring the test subject to touch the platform each time. * This may require a second person to record time values. Warmer temperatures allow adequate blood flow to all parts of the body, including extremities such as the index finger. If the test subject did not lift to the full height, the data produced an underestimate of the true value, while lifting too high would produce an overestimate. Personal Engagement This criterion assesses the extent to which the student engages with the investigation and makes it their own. Repeat exercise an additional two times. In this post, we give you 50 IB Biology IA Ideas to help you speed up your research process. Class Announcements. Higher rates equate to higher endurance of the fingers, and less fatigue in the muscles, seen in the higher temperatures like 30°C and 40°C. Adjust water bath for another temperature and repeat exercise until data has been collected for all five temperature settings. Hand – non-dominant: The dominant hand on a person has greater endurance than the non-dominant hand, thus changing hands would skew results. Ms. Maczuzak's IB Biology Site 2016 Exam. HL Biology IA Anthony Hans Jan 2016 Investigation Regarding the Correlation Between HDI and Mortality Rates due to Stroke Research Question What is the correlation between HDI and mortality rate due to stroke (measured in number of deaths per 100,000 of population), in countries with a HDI of above 0.75? Example Biology IA – IB Blog Calculate† the uncertainty, or standard error, by dividing the sample standard deviation, Sx, of the data by the square root of the number of observations/trials, n. a. Record times on data table. For example, while planning an investigation to study the effect of light wavelength on the rate of photosynthesis in Cabomba, the student may have adapted a method to measure the rate of photosynthesis taken from a textbook. IB Guides why fail? This guide is most definitely applicable to IB Biology and Chemistry. Start by performing this procedure in room temperature external conditions, close to 20°C. Factors Affecting Muscle Fatigue: The Effect of External Temperature on the Rate of Index Finger Lifts Background Information: Muscle fatigue has many factors that come into play. Finally, because this lab was so specified to the abilities of a single finger on a single hand of a single 17-year-old female, no generalizations could be made. Service Hours Reporting. Slopes of Best-Fit Lines for Each External Temperature These slopes represent the inverse of the rate. Studies have shown that tiny leaks of calcium in the muscles stimulates an enzyme which attacks muscle fibers. Also, you could not control temperature anymore, because one would have to wait for that warm day, or cold day. Finding a topic is one of the – if not THE – most important part of writing your IA so we want to make sure that you get it right! Your Internal Assessment (IA) is a project that you will have to complete in all your IB classes. a. These examples are from the IBO website. 2. Posted by gsw524 on May 18, 2016. Remember! Remember!

Biology Internal Assessment (IA) ... that I have compiled from online resources and my experiences that are roughly outlined by the topic covered in the IB Biology HL curriculum. DISCLAIMER: I provide this paper as a guide and sample NOT as a paper available for reproduction. Because each set of trials has a different standard deviation, each average also has a slightly different average uncertainty. The interval created for the rates of finger lifts for each external environment temperature increased as the temperature increased, thus showing a positive association between the two variables. From the background information, the hypothesis asserted that this relationship was caused by primarily the effect temperature has on the blood circulation of the extremities, like the index finger. 2. Change ). The grade boundaries for IB Physics and Biology need to be lowered significantly. All Lab Reports that you write for this class should follow this format, be labeled as such and include all applicable parts below! Research Question: What is the effect of varying external temperatures on the rate of index finger lifts for a 17-year-old female? To avoid this weakness in further investigations, one would suggest using methods to actually change the temperature of the environment surrounding the place of activity. Stretch Day IB BIO/ESS Lab Report Outline. IB’s Biology Internal Assessment (IA) is a make or break - you get it right and your grades rise, you mess it up and it all comes down. ( Log Out /  It scored 23/24, the mark that was lost was in the "Evaluation" section. Background Research Hypothesis: If the muscles which raise the index finger are exposed to varying external temperatures, then the rate of index finger lifts will increase as the temperature of the external environment rises, because when muscles fall below desired temperatures blood vessels constrict decreasing the amount of oxygen to the muscles which aids in the production of ATP and the onset of muscle fatigue, while higher temperatures dilate the blood vessels and allow more oxygen to reach the muscle enabling higher endurance. If O2 is depleted, the body switches to anaerobic ATP production. The ranges for all 5 external temperatures seems to be about the same, so the spread is consistent, however the minimum and maximum values differ greatly, especially between 0°C and 40°C. Hi all, Here is my Biology IA. Surface of action – flat counter: different surfaces could make the finger lifts easier/harder. Arm position – differing arm positions could alter the amount of blood flow to the finger, which must remain constant. This graph visually represents the changes in the slopes for each external temperature as well as a visual comparison for times at each interval of Number of Finger Lifts (10, 20, 30, 40, and 50). IB Mathematics Notes; HL Mathematics IA (18/20) IB English A: Language and Literature. (IB bio guide 2016, p.148) Nonetheless, I think it's better to do something from the HL topics, or at least use it as an extension (e.g. IB Biology Internal Assessment Rubric Personal engagement Mark Descriptor 0 The student’s report does not reach a standard described by the descriptors below. Students are required to write the Biology IA during the second year of their HL class. ATP, adenosine tri-phosphate, the energy source for all muscles, is required for a muscle contraction to take place. Within each topic listed below, we include the basic reasons for investigating each topic, what the possible independent variables and dependent variables are as well as the basic experimental setup! ( Log Out /  Calculate† the uncertainty, or standard error, by dividing the sample standard deviation, Sx, of the data by the square root of the number of observations/trials, n. a. We would like to show you a description here but the site won’t allow us. These calcium leaks accelerate the onset of muscle fatigue, although it is more prevalent in athletes who push their muscles regularly, thus not really pertaining to this investigation. Changing fingers skews the results. ... Osmosis & Diffsuion IB Biology Lab Report Rubric With Attached Example IA on Plasmolysis in Potatoes With Comments. Menu. What is the II of the IA in IB???

Subject then proceeded to do jumping jacks for 30 seconds. I hope the IB takes appropriate action to ensure fair assessment of its students. There was also a weakness in regulating the height of the lift. Reading List. Once again, some sort of computerized pressure sensor would offer more accurate data. Assessment model IV. Adequately controlling the external atmospheric temperature was a major weakness in this investigation. Although, problems remain with that kind of set up – one could not accurately change the temperature of the environment, rather only use what is available. I. Useful Links. 3. Subject was then asked to find his/her resting heart rate in 15 seconds. There should be a range two values, thus offering a range of rates. There is no overlap between these intervals, suggesting that there is a significant different between the external temperatures. IA - Internal Assessment - worth 20% of the final assessment II - Individual Investigation - ONE scientific investigation 10 hours in length Write- up - 6 to 12 pages long. A ice box cooler, or cold day, could offer lower temperatures while a sunny hot day could offer the warmer temperatures. 4. It may be useful for students who are lost for an idea, or teachers who are looking for something to inspire a particular student. 1. IB Maths IA - Bayes Theorem Help!

The most significant error to this lab was the treatment of the external environment. Although a water bath was suitable for exposing the hand to different temperatures very quickly, whenever the hand was removed from the water bath to perform the activity heat was either lost or gained to or from the atmosphere. I've omitted the conclusion… Join Sneeky and 7,864 supporters today. Hopefully it'll be a decent exemplar for you all. From the average values calculated for each trial, translate data into a line graph, where the Number of Finger Lifts is on the x-axis and the time taken to perform that Number of Finger Lifts on the y-axis. Regardless of whether or not there is still a presence of calcium, without the ATP, the muscle fatigues. I've omitted the conclusion… Perhaps a sensor under your finger could detect the pressure changes when lifting the finger and replacing it. How I got a 7 in IB HL Biology & HL Chemistry || IA, notes, resourcesHiii! 7. 2 Homeostatic mechanisms in the body take into account the external temperature of the body, and with a negative feedback response, adjust the body accordingly to prolong life. Change the external temperature of the subjects finger by creating a water bath with the set temperature of either 0°C, 10°C, 30°C or 40°C.
