C1 Investigate: What conditions do woodlice like? Lesson planning guide Learning objectives i Carry out a full investigation. ii Learn more about an organism and its habitat. Scientific enquiry iii Identify and control the key factors that are relevant to a particular situation. (Framework YTO Sc1 7c) iv Select and use appropriate equipment to collect information about habitats. (Framework YTO Sc1 7d) v Use repeat measurements to reduce error and check reliability. (Framework YTO Sc1 7e) vi Present and interpret experimental results. (Framework YTO Sc1 7f) vii Describe and explain what results show when drawing conclusions. (Framework YTO Sc1 7g) viii Evaluate the strength of evidence, e.g. indicate whether increasing the sample would have strengthened the conclusions. (Framework YTO Sc1 7h) Suggested alternative starter activities (5–10 minutes) Setting the context Introduce the apparatus Safety Brainstorming (1) Brainstorming (2) Discuss with pupils what living things need from a habitat to survive. Show pupils the apparatus available for the investigation. Guidelines about working with living things. Introduce the variables and decide what to measure. Consider if repeat measurements are needed. Investigation Activity Learning objectives see above Description Approx timing Activity C1c Practical ii, iii and iv 20 min Activity C1d Practical ii, v and vi Activity C1e Practical vi, vii and viii What conditions do woodlice like? Planning Pupils plan an investigation into whether the intensity of light affects the behaviour of woodlice. What conditions do woodlice like? Obtaining evidence Pupils carry out their investigation into whether the intensity of light affects the behaviour of woodlice. What conditions do woodlice like? Considering and evaluating the evidence Pupils consider and evaluate the evidence they collected. Target group C H E S 30 min 15 min Suggested alternative plenary activities (5–10 minutes) Review learning Group feedback Analysing Evaluating Teacher-led review of key variables and the relationship between light intensity and woodlice activity. In groups, pupils discuss if they had to change their plans as they did the experiment and why. Teacher-led discussion of whether pupils’ results match their predictions. Teacher-led evaluation of possible improvements to sampling methods. Learning outcomes Most pupils will … Some pupils, making less progress will … Some pupils, making more progress will … plan and carry out an investigation (given the question to investigate) realise that repeating measurements increases reliability collect and analyse data draw conclusions from their data describe possible improvements to their method. with help, plan and carry out an investigation (given the question to investigate) collect and, with help, analyse data draw conclusions from their data with prompting, describe possible improvements to their method. also decide if the evidence is strong enough to support their conclusion. Key words condition, variable Out-of-lesson learning Pupils could write their conclusion or evaluation at home. © Harcourt Education Ltd 2003 Catalyst 1 This worksheet may have been altered from the original on the CD-ROM.
