Task administration: This task can be completed with pencil and paper or online. Level: 5 Curriculum info: Science, Knowledge, Physical World Keywords: physics concepts, friction, air pressure, tyres Description of task: Task: Answer questions about car tyres. Assessment focus: friction; air pressure. Curriculum Links: Science capabilities The capabilities focus is brought about by the conversations you have and the questions you ask Capability: Use evidence This resource provides opportunities to discuss how using evidence/observations supports explanations. Science capability: Use evidence (TKI) Science capabilities: Use evidence Answers/responses: Y10 (06/1998) a) Friction (with the road surface). easy b) The pressure will have increased. difficult c) Before the journey/when tyres are cold. difficult Diagnostic and formative information: Common error c) At the start and end of a trip – 14% of students. Every X km, min, or hour, e.g., every 100 km – 14% of students. In the middle of a trip – 13% of students. When visiting a service station – 9% of students. What helps a racing car go fast?
