Teachers’ notes – Habitats 2 Synopsis In this activity, learners compare the two habitats they have studied in Unit 1.4.1 and explore seasonal changes within habitats. Initially, they list some of the things they found in each habitat and make a qualitative comparison through discussion. Learners consider some of the things they counted and measured in the two habitats and use bar charts and line graphs to record findings. Learners reflect on and self-assess their performance during their fieldwork enquiries and consider how they might improve. They create and present a ‘Fieldwork guide’ for others preparing to undertake habitat enquiries. Learners compare photographs of the same tree taken in different seasons and explore and discuss some of the seasonal changes that might be observed in habitats. Finally, they choose a plant and animal from one of their habitat studies and show how these might change from one season to another. Curriculum links Interdependence of organisms: 4. through fieldwork, the plants and animals found in two contrasting local environments, e.g. identification, nutrition, life cycles, place in environment 5. the interdependence of living organisms in those two environments and their representation as food chains 6. the environmental factors that affect what grows and lives in those two environments, e.g. sunlight, water availability, temperature 7. how humans affect the local environment, e.g. litter, water pollution, noise pollution Skills Communication: 1, 2 & 3 Enquiry – Planning: 2 & 3 Enquiry – Developing: 5 Enquiry – Reflecting: 5 & 6 Activities Tab 1 The first tab in this activity requires learners to list some of the things that they found in each of the two habitats they studied at the end of Activity 1.4.1. Again, if learners have not studied two contrasting local environments then different groups of learners might provide ideas for the habitat studied by their group and then comparisons of different habitats could be made. Questions are provided to support a qualitative comparison of two habitats. Tab 2 In this tab learners are asked to list some of the things they counted and measured in each habitat. For example, they might have counted the number of different types of flower and measured the temperature over the course of the day. Rollover questions encourage them to discuss what they counted and measured and to consider why these factors might be important. Tab 3 This tab provides learners with a blank template for a bar chart. They are asked to use the template to show the results of something they counted or measured in one of the two habitats they studied. The blank chart has 10 bars, which allows for a comparison to be made between the two habitats if required. If each group of learners has only studied one habitat then groups could be paired for this tab. Tab 4 It should be noted that drawing line graphs is usually seen as a level 5 demand and this tab might not be suitable for learners working below this level. The tab provides learners with a blank template for a line graph. They are required to draw a line graph to show one of the variables that they measured in each habitat. For example, they might have measured daytime temperature in the school garden and a local pond. Both sets of results could be drawn on the same line graph template. Again, results from different groups of learners might be more beneficial to compare. Remind learners that only continuous data can be used to construct line graphs. Tab 5 The aim of this tab is to encourage learners to reflect on their fieldwork enquiries and consider how they might improve. They are asked to create and present a ‘Fieldwork guide’ for others preparing to undertake habitat enquiries. When asking learners to create something for others it is always worth asking them to consider success criteria. In this instance they might consider their audience and determine the most relevant details to include and consider how to make the ‘Fieldwork guide’ coherent and engaging. Tab 6 This tab provides learners with four photographs of the same pear tree, taken in different seasons. They are asked to describe how the tree changes from one season to another and to consider how this might affect animals that live in or near the tree. This tab aims to introduce seasonal changes to habitats in a context that will be familiar to most learners. Tab 7 This tab requires learners to consider how one of the habitats they have studied might change from one season to another. The tab provides four recording boxes, labelled – spring, summer, autumn and winter. Learners are encouraged to draw and write their ideas about how the habitat might change from one season to another. The aim of this tab is for learners to reinforce their understanding of the effects of seasonal changes on plants and animals and where they live. As the next tab encourages a more specific consideration of changes to individual plants and animals, then more general consideration might be acceptable in this tab. Encouragement might be given for learners to consider when most plants begin to grow, flower and produce seeds and when many animals begin a new life cycle. Learners might consider when a habitat is likely to have more colour, growth and activity and explore reasons why. Tab 8 The aim of this tab is to develop learner’s ideas and understanding by encouraging a more specific exploration of plants and animals in a habitat. Learners are asked to choose one plant and one animal from a habitat they have studied and to show how these might change from one season to another. Encourage them to perhaps consider some of the less obvious and prominent plants and animals in their chosen habitat. Learners might use secondary sources to gather information to help develop their knowledge and understanding.
