Toy car and magnets 0 Overview Using this Resource Connecting to the Curriculum Marking Student Responses Working with Students This task is about magnetism. A bar magnet has been glued to the top of this toy plastic car. Question a) What would happen if another bar magnet was moved towards it as shown in the diagram? The toy car would: stay where it is and not move. move forwards. move backwards. turn around towards the magnet being held. Question 2Change answer b) Why was a plastic car used in this experiment and not a metal car? Task administration: This task can be completed with pencil and paper or online (with SOME auto marking). Level: 3 Curriculum info: Science, Knowledge, Physical World Keywords: physics concepts, forces, magnetism, magnets Description of task: Task: Select what would happen when like poles of a magnet come together, and explain why a plastic rather than a metal car was used in the investigation. Assessment focus: magnetism. Making Better Sense: Magnetic Fields Answers/responses: Y7 (03/1998) a) move backwards moderate b) Because the car itself would be attracted to the magnet. moderate Diagnostic and formative information: Common errors a) Option B - move forwards - was selected by 36% of students. b) A metal car is too heavy/plastic is lighter – 9% of students.
