IA Lab Report IB HL BIOLOGY
Introduction Short paragraph A simple introduction to your experiment and paper
Research Question Be very specific with your independent and dependent variable
Background Information Provide background information on the biological process you are studying – photosynthesis, germination, etc. Provide background information on the variable you are testing – why it might impact your experiment Explain why this experiment has biological significance – real world application – and/or why you are interested in the experiment
Hypothesis Does not need to be written as an “if, than, because” statement Be sure to include an explanation
Controlled Variables Do not include a variables table Write as a narrative Include variables controlled and why
Method Do not write as procedural steps Explain the procedure of your experiment in a narrative
Data Only include processed data in the body of your paper Informative title Units and uncertainty Placement of DV and IDV Number of sig figs
Table 1: The Impact of Antibiotics on the Growth of E. coli bacteria Type of Antibiotic Average Zone of Inhibition (mm +/- 0.5) Standard Deviation T test P value Are results significant? Distilled Water 2 .5 Penicillin 12 1 0.025 Yes Tetracycline 3 0.85 No
Statistics Average raw data Calculate the standard deviation for every average Run a t-test between each variation of your variable and the control Sample calculations will be placed in the appendix of your paper
Qualitative Data If you collected qualitative data include in a table in the body of your paper
Graph Title Label axes – include units and uncertainty Only graph processed data Include error bars on your graph – be sure to indicate what data was used to create the error bars
Graph 1: The impact of Antibiotic on the Growth of E. coli Error Bars represent +/- 1 standard deviation
Conclusion and Evaluation Question & hypothesis restated ALL Findings accurately retold Hypothesis rejected or accepted, with evidence Complete biological explanation of the experiment Comparison to other data Relates back to “real world application” of the experiment Most relevant limitations or sources of error are identified Discussion of confidence in the data Realistic improvements suggested
Literature Cited Use proper formatting
Appendix Include raw data in a table – follow rules for formatting a table Include your sample calculations One sample calculation for each type of calculation completed to process your data Pictures?
Additional Information Use IN TEXT citations These results are significant because they are contested by scientific context about the differences between name brand and generic drugs, as established by the United States Food and Drug Administration (FDA 2017)
Additional Information Scientific names – italics, capitalize genus, species is lower case After first time using the genus name can be abbreviated Lodge pole pine Pinus contorta P. contorta
