Year 12 Level
BIO5 Continuity of Life and Homeostasis BIO5 Continuity of Life and Homeostasis 2020 Major Practical – Investigating Germination Your task will be to design an experiment, carry it out and complete a written lab report. You may carry out the experiment on your own or in groups of 2-4, but each student must write up the experimental report independently. You will have some class time to set up your experiment but will also need to monitor your experiment and record your data for several days. This may be in and out of class time. Your task is to investigate a factor which affects germination. Some important information: You will have class time to plan and to set up your experiment and some time at the start of following lessons to record your results. You may have to check your experiment and record results on days which you do not have a class or at other times during the day so you will need to organise with your group how to do this. You will not be able to check your experiments at school over the weekend. Refer to the marking scheme and your class notes when planning your experiment. Available equipment: • Seeds (wheat, barley, peas, alfalfa) • Petri dishes • Plastic cups, plates, bowls • Ice cube trays • Paper towel, cotton wool, absorbent dishcloths • Light banks, lamps, cupboards and boxes • Water baths, fridge, freezer • Electronic balances • Materials for solutions (salt, sugar etc….) • Other equipment may be available upon request – please see your teacher. Final report: You will need to complete a written lab report on your investigation. A detailed guide that you were given in Year 11 on how to write a biology lab report is available on the Google Classrooms Page. You should also consult the mark scheme to ensure you are meeting the expected requirements. If you have any other questions about your experiment or your report, please come and see your teacher prior to the due date.

The topic of the investigation is identified and a research question of some relevance is stated but it is not focused. The topic of the investigation is identified and a relevant but not fully focused research question is described. The topic of the investigation is identified and a relevant and fully focused research question is clearly described. The background information and research provided for the investigation is superficial or of limited relevance and does not aid the understanding of the context of the investigation. The background information and research provided for the investigation is mainly appropriate and relevant and aids the understanding of the context of the investigation. The background information and research provided for the investigation is entirely appropriate and relevant and enhances the understanding of the context of the investigation. The methodology of the investigation is only appropriate to address the research question to a very limited extent since it takes into consideration few of the significant factors that may influence the relevance, reliability and sufficiency of the collected data. The methodology of the investigation is mainly appropriate to address the research question but has limitations since it takes into consideration only some of the significant factors that may influence the relevance, reliability and sufficiency of the collected data. The methodology of the investigation is highly appropriate to address the research question because it takes into consideration all, or nearly all, of the significant factors that may influence the relevance, reliability and sufficiency of the collected data. The report shows evidence of limited awareness of the significant safety, ethical or environmental issues that are relevant to the methodology of the investigation. The report shows evidence of some awareness of the significant safety, ethical or environmental issues that are relevant to the methodology of the investigation. The report shows evidence of full awareness of the significant safety, ethical or environmental issues that are relevant to the methodology of the investigation. Comment: An al ys is The student’s report does not reach a standard described by the descriptors that follow. The report includes insufficient relevant raw data to support a valid conclusion to the research question. The report includes relevant but incomplete quantitative and qualitative raw data that could support a simple or partially valid conclusion to the research question. The report includes sufficient relevant quantitative and qualitative raw data that could support a detailed and valid conclusion to the research question. Some basic data processing is carried out but is either too inaccurate or too insufficient to lead to a valid conclusion. Appropriate and sufficient data processing is carried out that could lead to a broadly valid conclusion but there are significant inaccuracies and inconsistencies in the processing. Appropriate and sufficient data processing is carried out with the accuracy required to enable a conclusion to the research question to be drawn that is fully consistent with the experimental data. The report shows evidence of little consideration of the impact of uncertainty on the analysis. The report shows evidence of some consideration of the impact of uncertainty on the analysis. The report shows evidence of full and appropriate consideration of the impact of uncertainty on the analysis. The processed data is incorrectly or insufficiently interpreted so that the conclusion is invalid or very incomplete. The processed data is interpreted so that a broadly valid but incomplete or limited conclusion to the research question can be deduced. The processed data is correctly interpreted so that a completely valid and detailed conclusion to the research question can be deduced. Comment: Ev al ua tio n The student’s report does not reach a standard described by the descriptors that follow. A conclusion is outlined which is not relevant to the research question or is not supported by the data presented. A conclusion is described which is relevant to the research question and supported by the data presented. A detailed conclusion is described and justified which is entirely relevant to the research question and fully supported by the data presented. The conclusion makes superficial comparison to the accepted scientific context. A conclusion is described which makes some relevant comparison to the accepted scientific context. A conclusion is correctly described and justified through relevant comparison to the accepted scientific context. Strengths and weaknesses of the investigation, such as limitations of the data and sources of error, are outlined but are restricted to an account of the practical or procedural issues faced. Strengths and weaknesses of the investigation, such as limitations of the data and sources of error, are described and provide evidence of some awareness of the methodological issues involved in establishing the conclusion. Strengths and weaknesses of the investigation, such as limitations of the data and sources of error, are discussed and provide evidence of a clear understanding of the methodological issues involved in establishing the conclusion. The student has outlined very few realistic and relevant suggestions for the improvement and extension of the investigation. The student has described some realistic and relevant suggestions for the improvement and extension of the investigation. The student has discussed realistic and relevant suggestions for the improvement and extension of the investigation. Comment: Co m m un ic at io n The student’s report does not reach a standard described by the descriptors that follow. The presentation of the investigation is unclear, making it difficult to understand the focus, process and outcomes. The presentation of the investigation is clear. Any errors do not hamper understanding of the focus, process and outcomes. Comment: The report is not well structured and is unclear: the necessary information on focus, process and outcomes is missing or is presented in an incoherent or disorganized way. The report is well structured and clear: the necessary information on focus, process and outcomes is present and presented in a coherent way. The understanding of the focus, process and outcomes of the investigation is obscured by the presence of inappropriate or irrelevant information. The report is relevant and concise thereby facilitating a ready understanding of the focus, process and outcomes of the investigation. There are many errors in the use of subject- specific terminology and conventions. The use of subject-specific terminology and conventions is appropriate and correct. Any errors do not hamper understanding. Exploration (6) Analysis (6) Evaluation (6) Communication (4) TOTAL (22)
