In this fun GCSE maths activity, students will delve into the exciting world of bicycle speedometers and put their accuracy to the test. By conducting this experiment, learners will better understand how speedometers work and sharpen their mathematical and analytical skills. Download the presentation below and allow the students to read the problem and contemplate how to model the situation mathematically. Some students may need assistance comprehending terms such as “front fork.” Encourage them to ponder the meaning of “ms-1,” such as the number of meters the wheel covers in one second. Furthermore, ask them to consider how they can determine the distance the wheel covers in a single rotation, two, or even 100 rotations. Problem Solving To solve this problem, the students will need to engage in logical thinking to determine the necessary information. One possible approach is to work backwards from the information required to answer the question (as shown below). We need the distance travelled (m) and the time taken (s) to calculate the speed. Given that the time is 1 minute, equal to 60 seconds, the question becomes: How can we find the distance? The wheel covers 0.5π meters per rotation, so for n rotations, the distance will be 0.5π x n. Consequently, the speed in ms-1 can be expressed as (0.5π x n)/60. The students can determine the percentage errors using this information and the speedometer readings. These errors vary slightly for each reading. Discussion points Examine how the students approached the problem, specifically analysing their thought processes. How did they determine the necessary information and identify ways to obtain it? You can review concepts such as calculating the circumference of a circle, working with percentages, rounding numbers, and ensuring precision. Potential GCSE content This activity will cover calculating the circumference of a circle from a radius, using compound measures (speed) and converting from minutes to seconds.
