About this resource: The British Broadcasting Corporation (BBC) interactive activity Characteristics of Materials (2014) allows users to test six (animated) materials (metal, paper, fabric, rubber, glass and plastic) to find out if they are waterproof, flexible, transparent and strong. Following this, users visit the Workshop where they examine the blueprints for six objects: a car tyre, saucepan, towel, notebook, sports bottle and a window. For each object, students are given the choice of four materials from the six examined previously to make their item out of. They must consider the properties of each material and select the one that is the most appropriate for the purpose of the object.
How to use this resource: Once loaded, the activity opens up in the ‘Testing room’. Instructions are written across the top for the user to work through at their own pace; the orange speaker on the left can be pressed to hear the instructions read out. Students drag and drop the materials, located in the middle of the bottom purple band, into the testing machine; these can be scrolled through using the red arrows on either side of the image. Material properties can be tested by clicking on the four question boxes to see the animation. Selecting the magnifying glass will load a summary of each material, including answering the four property questions. Additional help can be gained from the orange Help button located in the bottom left of the screen.
Clicking the green ‘Workshop’ button on the right of the material box will take you to the blueprint testing area. Blueprints can be scrolled and selected similarly to the materials in the ‘Testing room’ and object materials chosen by clicking on one of the four boxes. An image of the object made from that material will then appear, along with an explanation as to why the material choice would or would not be appropriate; these can also be heard by pressing on the orange speaker button in the top left corner of the box.
This activity allows the user to switch between ‘rooms’ at their own pace and it does not need to be completed sequentially, allowing for easy access to revisit any areas or demonstrate use of it in the classroom.
A classroom activity using this resource: Students could explore this activity as a class, in small groups or independently, making predictions based on their prior knowledge before testing the different material properties. A simple grid could benefit students to record the test results, assisting them when later testing the blueprint materials; instant feedback is however provided for this. Following this activity, students could apply their knowledge of different materials to design objects for specific purposes.
