Standard deviation can be calculated as b. 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. Perhaps a sensor under your finger could detect the pressure changes when lifting the finger and replacing it. What happens if you can't do an exam cause ur sick? IB Mathematics Notes; HL Mathematics IA (18/20) IB English A: Language and Literature. Original: Source. Remember! I scored a 6 in this class just a few marks below a 7 and my IA was a strong component of my score. The most significant error to this lab was the treatment of the external environment. Perhaps comparisons of age, gender, altitude, or any other constant variables for this experiment would be worthwhile. Stretch Day IB BIO/ESS Lab Report Outline. 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. I. Background Research Hand – non-dominant: The dominant hand on a person has greater endurance than the non-dominant hand, thus changing hands would skew results. Studies have shown that tiny leaks of calcium in the muscles stimulates an enzyme which attacks muscle fibers. 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! 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. 5. We would like to show you a description here but the site won’t allow us. IB. IB Biology: 30 investigation ideas for Biology IA 30 investigation ideas for Biology IA This page is a simple list of ideas for investigations. Calculate the average of each trial by adding up the times and dividing by three to find the average. Anaerobic metabolism produces lactic acid as a byproduct. 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). Biology IA Checklist for HL & SLÂ . Course description and aims II. 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. They need to perform a thorough investigation on a … Also, you could not control temperature anymore, because one would have to wait for that warm day, or cold day. Place hand in water bath for 5 minutes, to allow the hand’s muscles, blood vessels, and skin to adjust. Join Sneeky and 7,864 supporters today. Assessment model IV. All Lab Reports that you write for this class should follow this format, be labeled as such and include all applicable parts below! This is a template to help prepare you for completing these lab reports. 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. 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! Subject was then asked to find his/her resting heart rate in 15 seconds. Change ). The style and grade value depends on the subject. In this post, we give you 50 IB Biology IA Ideas to help you speed up your research process. Some scientists have reason to believe that lactic acid is not the culprit in muscle fatigue though. Menu. 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. You're not obliged to. 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. Remember! Reply. 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. 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. What is Internal Assessment. Lifts need to remain the same difficulty throughout the lab. Home; Blog; Chat; Submit Content; Languages A1. There should be a range two values, thus offering a range of rates. ... Osmosis & Diffsuion IB Biology Lab Report Rubric With Attached Example IA on Plasmolysis in Potatoes With Comments. Ms. Maczuzak's IB Biology Site 2016 Exam. Investigations exceeding this length will be penalized in Slopes of Best-Fit Lines for Each External Temperature These slopes represent the inverse of the rate. Remember to record data every set of 10 finger lifts. English B; English A2 It has been checked through plagiarism sites already so it will not work. There should be 5 lines – one for each external environment temperature. There was also a weakness in regulating the height of the lift. 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. The justification given for choosing the research question and/or the topic under It scored 23/24, the mark that was lost was in the "Evaluation" section. This video shows you how to present your processed data in a clear graph that meets the requirements for IB Biology. Here's a quick guide I've sketched out for a rough layout of an IA (this is also on my Chemistry IA page). What is Internal Assessment. There is no overlap between these intervals, suggesting that there is a significant different between the external temperatures. 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. b. 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. Your Internal Assessment (IA) is a project that you will have to complete in all your IB classes. Posted by gsw524 on May 18, 2016. Hi all, Here is my Biology IA. This could suggest that these data values are not significantly different; if we look at the extremes in temperature however, there is no overlap. Example Biology IA. 4 ATP is required in the sarcomere of a muscle cell to release the myosin cross head bridge from the actin molecules. Repeat exercise an additional two times. 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. 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). 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. 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. --Louis Pasteur. Biology guide First assessment 2016. Sample questions International Baccalaureate Diploma Programme Subject Brief Sciences: Biology—Standard level First assessments 2016 – Last assessments 2022 Once again, some sort of computerized pressure sensor would offer more accurate data. Students will spend 10 hours doing this investigation which will provide 20% of the overall assessment for the IB biology score (the IB … An independent variable of external environment temperature was applied to a dependant variable of time taken to complete 50 finger lifts. Biology Internal Assessment Purpose My interest in the ripening of fruit developed from an IB Guides why fail? 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? DISCLAIMER: I provide this paper as a guide and sample NOT as a paper available for reproduction. Adjust water bath for another temperature and repeat exercise until data has been collected for all five temperature settings. Service Hours Reporting. Personal Engagement This criterion assesses the extent to which the student engages with the investigation and makes it their own. Type of finger – index: different fingers have different strengths and thus different finger endurances. 6. Syllabus IB Command Terms Topic 1: Molecules of … Hopefully it'll be a decent exemplar for you all. I hope the IB takes appropriate action to ensure fair assessment of its students. Home ; AP & IB Biology ; IB Biology ; 2016 - 2022 IB Biology Curriculum ; Topic 1: Molecules of Life. Conclusion: The purpose of this investigation was to explore a factor that affected muscle fatigue. A conclusion paragraph is one of the most important parts of a lab report. Altitude of action – Oxygen amounts inhaled must remain constant, and changing altitudes during the lab would skew the data. Biology guide First assessment 2016. Another weakness was the method of counting the number of finger lifts. These IB DP subject briefs illustrate four key course components. 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. 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. Your Internal Assessment (IA) is a project that you will have to complete in all your IB classes. 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. 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… 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. 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. 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. Research Question: What is the effect of varying external temperatures on the rate of index finger lifts for a 17-year-old female? None of them are perfect so make sure you look at the moderators comments to see where points were deducted and why. Record times on data table. I. Hi all, Here is my Biology IA. Background Research I could find the following: "The internal assessment requirements at SL and at HL are the same." 3 Calcium, Ca2+, however, does affect muscle fatigue. 1. something about enzymes going more in detail or using inhibitors). Error bars of many of the closer temperatures seem to overlap. Regardless of whether or not there is still a presence of calcium, without the ATP, the muscle fatigues. Uncertainty of a Spectronic 20. a. I've omitted the conclusion… ( Log Out /  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. * This may require a second person to record time values. IB Science Lab Report Template Lab reports make up 24% of your final Biology & Chemistry grade towards your IB Diploma. Example IB Biology IA - Free download as PDF File (.pdf), Text File (.txt) or read online for free. While variables like age and gender could speak to muscle capability, a variable such as altitude could speak to the oxygen differences in habitants of different altitudes. What is the II of the IA in IB??? IB to A-level conversions !! Because of this, I would suggest a method in which a computer records the cumber of finger taps performed. As a matter of fact, there are numerous limitations and weaknesses in the design of the investigation. Course description and aims II. 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”. The style and grade value depends on the subject. IB Biology. Change ), You are commenting using your Twitter account. Curriculum model overview III. The rates also correspond to an inclination for faster action at higher temperatures. 2. 1.
