Making a cradle using magnets that repel each other Newton’s cradle uses swinging spheres to show how the conservation of momentum and the conservation of energy works. The device was named after Sir Isaac Newton and designed by French scientist Edme Mariotte. This is one of a set of resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within science and design and technology. This resource focuses on producing a magnetic Newton’s cradle that uses magnets which repel each other instead of the usual metal spheres. This is a great way for students to learn all about magnets and could be used as a one-off activity or as part of a wider unit of work focusing on magnets and magnetism. It can also be used in conjunction with other IET Education resources, developed alongside the School of Engineering at Cardiff University. This activity will take approximately 65-90 minutes. Tools/resources required Circular magnets with holes in the middle (with N and S poles) 150 mm lengths of dowel 75 mm lengths dowel 100 – 120 mm long pieces of string (6 per unit being built) Masking tape Example of a ‘regular’ Newton’s cradle. Scissors Hot glue guns, if appropriate Magnetic forces Magnets are made from materials such as iron and nickel and they have a north pole and a south pole. When the north pole of a magnet is placed near the south pole of another magnet, they will attract each other. When two poles that are the same are placed near each other, they will repel each other. For example, north to north and south to south. The engineering context Engineers need to know the properties of magnets, which materials are magnetic and which materials are non-magnetic. This knowledge could be used when identifying and creating potential solutions to future engineering problems. For example, when developing green transport solutions. Suggested learning outcomes By the end of this activity students will be able to describe magnets as having two poles – north and south, they will understand that magnets either attract or repel each other and they will be able to make and test a ‘magnetic’ Newton’s cradle.

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.
