Lifts need to remain the same difficulty throughout the lab. 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. I can't find it in the bio guide, in any case. 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. what do you consider to be a "good" IB score? 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. Ms. Maczuzak's IB Biology Site 2016 Exam. We would like to show you a description here but the site won’t allow us. Each value for the averages has its own uncertainty because a standard error method for calculating uncertainty was used. ... Osmosis & Diffsuion IB Biology Lab Report Rubric With Attached Example IA on Plasmolysis in Potatoes With Comments. Research Question: What is the effect of varying external temperatures on the rate of index finger lifts for a 17-year-old female? 2. 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. How I got a 7 in IB HL Biology & HL Chemistry || IA, notes, resourcesHiii! IB Biology HL BTHS Materials ­ 2 timers, photographs of poses, pencil, paper Procedure First, a subject was found and asked to sign the consent form. Standard deviation can be calculated as b.

It may be useful for students who are lost for an idea, or teachers who are looking for something to inspire a particular student. I could find the following: "The internal assessment requirements at SL and at HL are the same." The most significant error to this lab was the treatment of the external environment. 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. View IA Sample - Fruit ripening 2016.doc from IB BIOLOGY 101 at Riverdale High School, Fort Myers. 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. 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. IB Mathematics Notes; HL Mathematics IA (18/20) IB English A: Language and Literature. Start by performing this procedure in room temperature external conditions, close to 20°C.

Surface of action – flat counter: different surfaces could make the finger lifts easier/harder. I've omitted the conclusion… The file below contains ideas for topics you can build your IA around. 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. Remove hand from water bath, dry with a towel, and repeat steps 2-3. Usually, ATP is created aerobically, with the presence of O2. Are you struggling with choosing your topic for your IB Biology IA? Person – 17-year-old female: Different people have different finger endurances, thus not keeping the person performing the finger lifts constant would skew results. The hypothesis inferred that with an increase in external temperature there would be an increase in the rate of index finger lifts. ( Log Out /  --Louis Pasteur. In this post, we give you 50 IB Biology IA Ideas to help you speed up your research process. 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. Example Biology IA. Acknowledgment . You're not obliged to. 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. Curriculum model overview III. Remember! IB Biology: 30 investigation ideas for Biology IA 30 investigation ideas for Biology IA This page is a simple list of ideas for investigations. Uncertainty of a Spectronic 20. Like Like. Have a test subject perform 50 finger lifts with the index finger of their left hand while another person times them. 6. Anaerobic metabolism produces lactic acid as a byproduct. Here's a quick guide I've sketched out for a rough layout of an IA (this is also on my Chemistry IA page). Record times on data table. Another weakness was the method of counting the number of finger lifts. The rates also correspond to an inclination for faster action at higher temperatures. 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. Curriculum model overview III. These examples are from the IBO website. From these data, the hypothesis is supported. Because each set of trials has a different standard deviation, each average also has a slightly different average uncertainty. External temperature does seem to have an effect on the onset of muscle fatigue in the left index finger of a 17-year-old female. ( Log Out /  Some scientists have reason to believe that lactic acid is not the culprit in muscle fatigue though. Specifically, the question asked the effect of external temperature on the rate of index finger lifts in the left hand of a 17-year-old female. 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. 3 Calcium, Ca2+, however, does affect muscle fatigue. Subject was then asked to find his/her resting heart rate in 15 seconds.

Here's a quick guide I've sketched out for a rough layout of an IA (this is also on my Chemistry IA page). 1 The evidence of personal engagement with the exploration is limited with little independent thinking, initiative or insight. Data processing involves, for example, combining and manipulating raw data to determine the value of a physical quantity (such as adding, subtracting, squaring, dividing), and taking the average of several measurements and transforming data into a form suitable for graphical representation. A conclusion paragraph is one of the most important parts of a lab report. The interval is created from the highest and lowest values with the uncertainty calculated in for the total time. I hope the IB takes appropriate action to ensure fair assessment of its students. Resources for Data Coming Out of Sarka Park. This is a template to help prepare you for completing these lab reports. Class Announcements. This guide is most definitely applicable to IB Biology and Chemistry. How does this speak to muscle fatigue onset? IB. Remember! Change ). IB Biology. The justification given for choosing the research question and/or the topic under The external temperature did not remain constant throughout the trials for this reason, and the data becomes questionable as to its ability to show a relationship  between temperature and muscle fatigue onset. Hand – non-dominant: The dominant hand on a person has greater endurance than the non-dominant hand, thus changing hands would skew results. b. 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. 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. 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! 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. This explanation fits the data observed in this investigation. I. In this post, we give you 50 IB Biology IA Ideas to help you speed up your research process. These IB DP subject briefs illustrate four key course components. 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). 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! IB Guides why fail? These IB DP subject briefs illustrate four key course components. The style and grade value depends on the subject. Repeat exercise an additional two times. ATP, adenosine tri-phosphate, the energy source for all muscles, is required for a muscle contraction to take place. Altitude of action – Oxygen amounts inhaled must remain constant, and changing altitudes during the lab would skew the data. Thermoregulation acts when the body is in undesirably low temperatures, senses by receptors on the skin.

The style and grade value depends on the subject. 3. Slopes of Best-Fit Lines for Each External Temperature These slopes represent the inverse of the rate. I give many of my IB Biology resources away, for the benefit of students and teachers around the world. Change ), You are commenting using your Google account. There was also a weakness in regulating the height of the lift. 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. Conclusion: The purpose of this investigation was to explore a factor that affected muscle fatigue. 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. Therefore, it’s super important that your IB Biology IA gets as high a mark as possible. 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. This video shows you how to present your processed data in a clear graph that meets the requirements for IB Biology. Join Sneeky and 7,864 supporters today. This shows that higher external temperatures correlate with faster finger lifting action for the 50 finger lifts. 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. 4. Hopefully it'll be a decent exemplar for you all. It scored 23/24, the mark that was lost was in the "Evaluation" section. As a matter of fact, there are numerous limitations and weaknesses in the design of the investigation. In … Your Internal Assessment (IA) is a project that you will have to complete in all your IB classes. 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. Biology Internal Assessment Purpose My interest in the ripening of fruit developed from an 2. Ms. Dillman - IB Biology: Home IB Biology II > > IB Biology III > > IB Chemistry Calender ...

Once again, some sort of computerized pressure sensor would offer more accurate data. Search this site. NOS IA Examples; Tutoring Services; 2016 - 2022 IB Biology Curriculum "Chance Favors the Prepared Mind." There is no overlap between these intervals, suggesting that there is a significant different between the external temperatures. If there is not a sufficient amount of ATP, the myosin remains attached to the actin, and can no longer swivel. (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. Assessment model IV. Biology guide First assessment 2016. Independent variable: Temperature of external environment 0°C, 10°C, 20°C(control), 30°C, and 40°, Dependant variable: Rate of index finger lifts Calculated by # of finger lifts (50) / time taken to perform finger lifts(seconds). It scored 23/24, the mark that was lost was in the "Evaluation" section. 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. Place hand in water bath for 5 minutes, to allow the hand’s muscles, blood vessels, and skin to adjust. The AP/IB Chemistry Lab Report. Assessment model IV. 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. Untitled. Higher rates signified more activity, indicating a higher level of endurance and ultimately a later onset of muscle fatigue. Don’t worry, we’ve all been there. Investigations exceeding this length will be penalized in Regardless of whether or not there is still a presence of calcium, without the ATP, the muscle fatigues. English B; English A2 Biology guide First assessment 2016. Stuck for Ideas planning your Biology IA? Because of this, less oxygen is delivered to muscles in lower temperatures, thus inducing a switch to anaerobic metabolism quicker than in higher temperatures. Arm position – differing arm positions could alter the amount of blood flow to the finger, which must remain constant. * This may require a second person to record time values. Also, you could not control temperature anymore, because one would have to wait for that warm day, or cold day. This could suggest that these data values are not significantly different; if we look at the extremes in temperature however, there is no overlap. What happens if you can't do an exam cause ur sick? Biology guide First assessment 2016. Stuck for Ideas planning your Biology IA? Error bars of many of the closer temperatures seem to overlap. It has been checked through plagiarism sites already so it will not work. What is the II of the IA in IB??? Example IA's . 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. IB Science Lab Report Template Lab reports make up 24% of your final Biology & Chemistry grade towards your IB Diploma. 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. Because of this, I would suggest a method in which a computer records the cumber of finger taps performed. An independent variable of external environment temperature was applied to a dependant variable of time taken to complete 50 finger lifts. Biology guide First assessment 2016. 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. The International Baccalaureate Biology Internal Assessment makes up 20% of the final grade achieved by Biology HL and Biology SL students. 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. Background Research ... IB Biology SL Examination 2016”. 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. ( Log Out /  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”. About; Uncategorized. 1. The grade boundaries for IB Physics and Biology need to be lowered significantly. If O2 is depleted, the body switches to anaerobic ATP production. Personal engagement may be recognized in different attributes and skills; these could include addressing personal interest or showing evidence of independent thinking, creativity, or initiate in the designing, implementation or presentation of the investigation. 1. Personal Engagement This criterion assesses the extent to which the student engages with the investigation and makes it their own.
