More repeats help you identify anomalies and omit them if necessary. How will you minimise harm/impacts on the environment. (Exactly what you will be measuring) Controlled � state each of the variables that you can and will control; state how you will control each one and why it needs to be controlled (ie � would would happen to the expected result If this factor was higher/lower and why?). An improvement could be to use more precise apparatus. IB students are evaluated externally, two ways. Although only one piece of work is completed as a full IA and submitted you will be doing practice pieces of work (60 hours for higher and 40 for standard ) and it is essential that you complete each of these to the best of your ability so that the feedback you get is meaningful. This does not mean you can�t keep things simple though! Pay attention to any practical skills or methods that you cover at any point in the course as these will help you to complete your IA correctly. Refer back to the previous information to justify to yourself why these uncertainty values have been given ( ie what type of apparatus is being used).

If your results don�t match your expectations or published data refer back to what you would have expected and why. PDF (2.2MB) Tick to download 2018 NH Human Biology. Internal Assessment Your final IB grade for your group 4 science course is based on three examination papers and an independent research project, called an �internal assessment� or IA .Your Internal Assessment consists of one individual scientific study. One way is through the internal assessment lab report, which accounts for 20% of the overall IB score. NB for a standard deviation to be valid it should really be based on a large number of repeats (at least 20if this is not possible calculate the SD but include a comment that it is not valid if your data does not show a normal distribution or you have too few repeats � it is still worth doing it as it gives you an idea of the reliability of your results. Identify anomalous results e.g. Also- how close were your points to the line of best fit. Self-management � You are responsible for your work, including meeting deadlines. Features Fully online format, accessible anytime, anywhere. Closer= more accurate. A balance gives measurements in grams to 2 decimal places. You must also demonstrate a justification for your research question; perhaps there is some personal significance, interest or curiosity here. Could a comparison chart or electronic devise be used instead? Revision of IB Biology Prescribed Practicals (Paper 3, Section A) Posted by studynova in IB Biology. Would a rate be useful � check your calculations as errors will drop marks. Due to the amount of content needed for the IB Biology Exam, it is important to have a go-to source of any information that could come up. Think � can they at least be monitored to see if they vary? It covers the major topics in biology, Have a look at past papers and you will see they are not deep questions. If it�s a book: Barber, J. Tribes of Kenya. You need to refer to these when writing up investigations (Consider this- I could measure out 10 mls of liquid but �the real value� could actually be 10.05 mls but I wouldn�t notice this if my measuring cylinder only had whole mls on the scale. Features Fully online format, accessible anytime, anywhere. The core content follows a coherent and logical story through biology. It is a graded assignment for the class and is incorporated into your IB score for the course. Evaluation Consider your data: Evaluate your results. The content has been updated from the previous Pearson Edexcel International Advanced Subsidiary in Biology and Pearson Edexcel International Advanced Level in Biology qualifications. The Notes (for the 2016 syllabus) The full set of notes - Full HL Biology Notes Alternatively - a zip file with the notes separated by topic 1. NB � It would be sensible for you to measure the amount of liquid here as 25mls. t-test and does your data processing need a null hypothesis? Evolution 6. Quote these uncertainties: On your apparatus list (This allows people to copy your method using apparatus of the same precision) In the headings of results tables On the axis of graphs. �1 or 2 Eg. This doesn�t affect your uncertainty value as they only relate to measured values (as opposed to estimated ones). Evaluate the impact of the limitations. Therefore I cannot be confident that my mean is accurate. The content is relevant for students who have achieved a GCSE in Biology and who want to study this subject at a higher level. * + , N v x y z { | ~ � � � ��ȱ��ׄ��oW�B-B )hl h�X 5�>*CJ OJ QJ \�^J aJ )hl h�O� 5�>*CJ OJ QJ \�^J aJ /j hl h�G� 5�OJ QJ U^J mH nH u)j h�q� 5�OJ QJ U^J mH nH uhl hD� 5�OJ QJ ^J hl hD� 5�CJ4 OJ QJ ^J hl hD� CJ8 OJ QJ ^J ,j hl hD� OJ QJ U^J mH nH u hl hD� CJ� OJ QJ ^J hl hD� 5�CJ8 OJ QJ ^J /j hl h�q� 5�OJ QJ U^J mH nH u * , - 8 K L M N O P v w x z ~ � � � � b Updated 2015. What did you control well? Limitations will reduce the confidence you can have in the conclusions you draw from your investigation. The uncertainty tells you how much your measurement could be �out� by.) Did the precision of your apparatus lead to uncertainties you consider to be unacceptable? Was there any preliminary results, or research that helped you to formulate your method. c A full printable list of the syllabus can be seen here. Time allocation � Ten hours of class time but you may be able to do additional work outside of class. Now that you have evaluated do your results really allow you to answer your research question. (IE is certain apparatus recommended over an alternative elsewhere? For ecology practicals ensure that you describe your sampling technique very specifically and justify it. While there are core skills and activities common to both SL and HL students, students at HL are required to study the options and some topics in greater depth as well as some additional topics. # $ % d Q S T � � � � $ � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � dh gd�/� ��^��gd@7 � ^� gd@7 dh gd�/� gd�/� gd�/� 0 c d g � � � � A small number of repeats (or none at all) is problematic as it reduces your ability to judge reliability. Please note the following specifications for file sizes and file types: Candidates should keep files to the smallest possible size that does not negatively affect the quality of the work submitted. The minimum should usually be 5 values of IV and 5 repeats, but the quantity of data will depend on the complexity of the experiment. Ecology 5. There are two types of IB assessment: Internal and External. Report length � 6 to 12 pages (excessive length will be penalised). Its uncertainty would be � 0.01g Estimated uncertainties When you are counting something (particularly observations on living things) you will have an uncertainty. At the beginning of Paper 3, they might ask brief questions on these experiments. Revised to match the specifications and follow the structure of the 2014 Group 4 subject guide, our International Baccalaureate (IB) Diploma Biology textbook and enhanced eBook feature exam guidance, everyday use and industry examples to highlight relevance and context,and make clear links to the Learner Profile and IB core values.
