Teaching ideas for teaching year 3/4 forces and the properties of materials. This is a second unit of work. I suggest this unit be completed by Y4 students rather than Y3 students as it is harder than my first unit. http://www.slideshare.net/j_villis/forces-and-materials-teaching-ideas-jvillis
These ideas are linked to the Australian Curriculum. Additional teaching ideas related to technology can be found on one of my websites called http://technologiesjvillis.weebly.com/ .

Student work samples will be added to this PowerPoint after I have taught the lessons.

  • 2. Forces and the Properties of Materials 2 Teaching ideas by Joanne Villis AUSTRALIAN CURRICULUM (Y3/4) Investigate how forces and the properties of materials affect the behaviour of a product or system (ACTDEK011) Investigate the suitability of materials, systems, components, tools and equipment for a range of purposes (ACTDEK013) Generate, develop, and communicate design ideas and decisions using appropriate technical terms and graphical representation techniques (ACTDEP015) Evaluate design ideas, processes and solutions based on criteria for success developed with guidance and including care for the environment (ACTDEP017)
  • 3. Forces and the Properties of Materials 2 Teaching ideas by Joanne Villis BRIDGE DESIGN INVESTIGATION Aims: Students investigate the strength of materials (ACTDEK013) Students investigate different methods of joining and assembling in order to build a bridge (ACTDEP015) Students explore how the construction of a bridge effects the amount of load it can hold (ACTDEK011) Students evaluate their group’s bridge design in terms of functionality and aesthetic qualities (ACTDEP017) Lesson 1: Have a class discussion about bridges. Where have students seen bridges before? What do they look like? What is their purpose? Ask students to create a concept map about bridges using the following sub categories: (1) Used for (2) Made of (3) Looks like (4) Interesting things I know about bridges.
  • 4. Forces and the Properties of Materials 2 Teaching ideas by Joanne Villis Lesson 2-4: As a class brainstorm the functions of a bridge. What must it be able to do? (ie reach from one side to the other and support a load). Show students a range of materials (ie cardboard, toilet rolls, spaghetti, marshmallows, straws, tooth picks, masking tape, boxes, lego). Place students into small groups and ask them to discuss what they could do to test the strength of materials? What could they do to find out which is the weakest and which is the strongest? Then ask groups to select 4 materials and design an investigation to test the strength of each material. Group investigations need to have an aim, list of materials needed, method and some sort of way/method of recording the results. Then students are ready to conduct their investigation.
  • 5. Forces and the Properties of Materials 2 Teaching ideas by Joanne Villis When conducting investigations I like to let students use an app called Explain Everything. The app costs $3.79. It allows students to take photos, annotate, record audio etc. If you don’t have the app and have a limited budget, another great app is called Educreations. This app has similar functionalities. However, this app doesn’t allow you to capture and take recordings off the iPad. If you don’t have access to iPads I recommend you try and access digital cameras of video recorders. Any of these technologies enable students to capture elements of their investigation in order to reflect on later.
  • 6. Forces and the Properties of Materials 2 Teaching ideas by Joanne Villis Rather than asking students to write a reflection about their investigation I like to ask students to share their discoveries with the class. Allow each group time to report back to the class on what they did and what they discovered. Lesson 5: Place students in small groups and ask them to discuss what they might use to join materials together in order to build their bridge? What joining techniques might they use? Before students begin their discussion show them a range of materials to select from (ie sticky tape, masking tape, bluetac, marshmallows, glue sticks, PVA glue, rubber bands). Then ask students to create a PMI (positives, minuses, interesting points) chart, and identify a PMI for various joining materials.
  • 7. Forces and the Properties of Materials 2 Teaching ideas by Joanne Villis Lesson 6 – 7 : This is the design phase. Let students know that they have been asked to design a bridge using junk material (use the same materials which were used during lesson 2 to 5). Give them your design requirements (ie the length of the bridge and the load it is required to hold). I let students choose to work alone or in pairs. Ask students to draw a few bridge designs and label the materials they might use. This may be completed using paper and pencil, an app or design software such as Google Sketch Up 8. Google Sketch Up 8 is free software which can be downloaded.
  • 8. Forces and the Properties of Materials 2 Teaching ideas by Joanne Villis Lesson 8-10: This is the making stage. Allow students to make their bridges. I wouldn’t make students stick to their original designs. Allow them to re-do, re-build and re-think as they go. However, I do see the need for a time limit otherwise the making stage could go on forever. Encourage students to make and test, test and modify. During the making stage it is ideal for students to be able to digitally capture the stages of their thinking. Lesson 11-12: This is the evaluating and sharing stage. Allow each student or each pair to share their bridge design with the class. Additional online resource: Building Big- all about bridges
