LKS2: Modern Britain Theme 4: Dress & Dance Session 7: Investigating different types of plastic Science/Art Range and Breadth: Sci: 1c Use a range of sources of information and data, Session 8: Plan and carry out an investigation Science Range and Breadth: Sci: 1d Use first-hand and secondary data to carry out a including ICT-based sources. Art: 5d Investigate art, craft and design in the locality and in a variety of genres, styles and traditions. range of scientific investigations, including complete investigations. 2b Recognise that there are hazards in living things, materials and physical processes, and assess risks and take action to reduce risks to themselves and others. PoS Science: Grouping and classifying materials [Main] PoS Science: Investigative skills Objectives Chn learn about different types of plastic and what they are used for. Identify and sort plastic containers into diff types of plastic. 1a Compare everyday materials and objects on the basis of their material properties, including hardness, strength, flexibility and magnetic behaviour, and to relate these properties to everyday uses of the materials. Objectives Chn suggest ideas for an investigation. They plan and carry out an investigation and record their results. 2a Ask questions that can be investigated scientifically and decide how to find answers. 2c Think about what might happen. 2d Make a fair test or comparison by changing one factor. PoS Art: Knowledge and understanding PoS Science: Considering evidence and evaluating Objectives Look at the work of artists who use recycled materials and make a sculpture as part of a small group, using the materials they have collected. 4b Investigate materials and processes used in art, craft and design and how these can be matched to ideas and intentions. Objectives Chn record results. 2j Use observations, measurements or other data to draw conclusions. 2k Decide whether these conclusions agree with any prediction made and/or whether they enable further predictions to be made. [Main] Whole class teaching: In advance ask chn to bring in as many different Whole class teaching: You will need 3 different plastic carrier bags, weights and washed out plastic containers/packaging with the little recycling symbol as possible. Have a look at a range of plastics and other materials for chn to investigate. With the chns help write down some properties of plastics. Strong, flexible, waterproof, etc. Then brainstorm possible ideas for investigations involving plastics. This could be fairly loosely based around plastics, the main thing is the thinking about the investigations e.g. Which socks/tights are the ‘stretchiest’? Which makes the better parachute - paper or polythene? Which materials hold the most multilink cubes when floated on water? Which is the strongest shopping bag? Model planning an investigation as a class. Choose 3 different plastic shopping bags and investigate which is the strongest by adding weights or tins until it breaks. Fill in the investigation frame (session resource) together as far as the prediction. http://www.wrap.org.uk/recycling_industry/information_by_material/plastics/types_of_plastic.html or http://www.wasteonline.org.uk/resources/informationsheets/plastics.htm#_Types_of_plastic Read simplified version of Benefits and Types of Plastic in session resources. Sit chn in a circle and share out the plastic containers. Take turns to put the containers by the correct label (cut up enlarged version of session resource in strips). Do the containers match the labels? Show the chn the images of sculptures made from recycled materials (session resources). Can they recognise any of the parts used? Now they will make their own sculptures using plastic ‘junk’. Careful of sharp edges with brittle plastics! Easy/Medium/Hard In pairs/groups of 3 or more (depending how much ‘junk’ you have), chn make creative plastic sculptures from the materials brought in. They need to sit and look at their materials first to see what it suggests to them. There needs to be plenty of discussion and they should not start until the group is in agreement. Only then do they start to tape/glue the plastic containers together. Plenary Look at each other’s creations. Say what they like about them and why. Easy/Medium Medium/Hard As a group investigate –Which is the Chn plan and carry out an investigation in strongest shopping bag? Finish filling in pairs or small groups based on the ideas the investigation sheet. Record their they brainstormed. They think about how results on a simple graph (session they can record their results (graph, resources). table, diagram etc). Plenary Review and discuss what they find out. Think especially about explaining results. © Hamilton Trust 2011. This activity may be adapted for use by a teacher in his/her own class. It may not be reproduced for any other purpose.
