A fun engineering challenge for KS3 that will give students the opportunity to test boat hull designs in a test tank. Through this process, students will learn about the importance of applying relevant scientific and mathematical understanding when refining and developing an idea. This activity allows students to explore and develop their critical thinking and decision-making skills through a practical approach. The experiment ensures a ‘fair’ set of results is produced. The success of their overall boat hull design is directly dependent upon how well they apply their knowledge and understanding across the disciplines. In addition, key learning points needs to be reinforced through mathematics. The students could carry out initial research into different hull shapes used for various types of boat, and they should produce an image board of hulls with annotations to explain why the shape of the hull is appropriate for the particular type of boat. Types of boat hulls that could be researched include yachts, cruise ships, speed boats, fishing boats, container ships, and catamarans. This activity is designed to be taught through science and design and technology simultaneously, as a cross-curricular project and ideal for use in a STEM Club. However, it can also be tackled independently from each subject. Tools/resources required Test Tank (the construction is a fairly simple activity and can be undertaken by your KS3 students (as an after school activity) or by a technician) Vacuum Former High Impact Polystyrene/MDF or softwood blocks Optionally, modelling clay General Workshop Facilities Stopwatch Masses with a suitable holder The engineering context The focus of this activity is on the principle of hydrodynamics (a similar set of principles to aerodynamics but involving water). Suggested learning outcomes By the end of this activity students will be able to understand the importance of testing models and prototyping within the development of an idea, the need for streamlining in boat design and the principles of hydrodynamic design. Students will also be able to refine ideas in order to improve outcomes, they will be able to relate the shape of the hull to speed and the forces it needs to withstand maximum efficiency and they will be able to apply scientific and mathematical understanding to an engineering context.

Organise water filtration components to create a safe water supply system Activity info, teachers’ notes and curriculum links This activity challenges students to work in small teams to design a water supply system for a small town of 5,000 inhabitants. They have to work within a budget, including giving themselves a profit margin. The activity offers strong opportunities for cross-curricular work with Enterprise.

Calculate journey times from one country to another A costly and sometimes very long aeroplane journey is currently the only option if you intend to travel a long distance. However, what about in the future? One method that has been proposed is the vacuum tube train. The vacuum tube train may be able to reach speeds of 4,000 mph, but is it a realistic option? Activity: Use the Speed Equation to Calculate Journey Times In this fun maths activity for KS3, students will use the speed equation to calculate how long it takes to travel to destinations around the globe from the UK via today’s global transport options. They will then be introduced to a new concept in global travel: the vacuum tube train. Students will work in pairs or small groups to complete the tasks on the handouts below. Handout Journey Times A is for higher-ability students, and Journey Times B is for the less able. Students completing the handout Journey Times A may have to be informed/reminded of the speed = distance/time equation and how to use it to calculate the journey times. This activity can be used to introduce ideas about the environmental, economic, ethical and social impacts of each type of global transport. For example, comparing fuel efficiencies, the impact of infrastructure on the environment and how polluting they are. Suggested learning outcomes By the end of this activity, students will be able to calculate time using the speed equation, and they will be able to identify issues surrounding global transport. The engineering context Engineering has constantly propelled human progress, and the vacuum tube train is a testament to this innovation. This cutting-edge transportation marvel utilises sealed tubes to create a low-pressure environment, drastically reducing air resistance. Maglev technology suspends the train, eradicating friction for unparalleled speed. The engineering behind the vacuum tube train merges aerodynamics, materials science, and electromagnetic systems, enabling mind-boggling velocities. As we strive for more sustainable and efficient transit solutions, this exemplifies the potential of engineering to reshape our world, revolutionising travel and underscoring the limitless possibilities when science and ingenuity converge.
