Learn how mathematicians predict UK’s future water usage In this activity students will explore water consumption by looking at mathematical modelling and its real-world application in predicting water usage. Students will estimate their daily water consumption, interpret complex data, and apply their mathematical skills to understand why water usage is a significant issue. This is one of a set of resources developed to support the teaching of the secondary national curriculum, particularly KS3. It has been designed to support the delivery of key topics within maths, science and design & technology (DT). This lesson plan follows on from Water Conservation and continues the theme of water usage developed in the Sewage Tunnels activity but can be delivered independently should the teacher wish. Activity: Comparing water usage within the UK to that of other countries In this activity, students start by estimating their daily water usage. They then delve into complex data from the Environment Agency, interpreting different scenarios and their potential impact on future water requirements. Students will develop their own spreadsheet tool, inspired by the one on the Southern Water website, to help others estimate their water usage. They’re encouraged to improve upon the existing tool and even write to the Water Board with their suggestions. Download our activity overview, presentation and worksheet for a detailed lesson plan for teaching students about water consumption. We also have a class quiz. The engineering context This activity highlights the intersection of mathematics, science, policy-making, and engineering in addressing real-world problems.

Understanding levers and forces This STEM activity aims to develop children’s understanding of levers, specifically the seesaw class lever, one of the simplest forms of machine used to change the magnitude or direction of a force. Making a small seesaw model is a fun-filled way to introduce children to the concepts of levers and forces. By making simple levers, learners will grasp how the effort applied to a lever affects the load. This hands-on project not only sparks their curiosity but also encourages active learning. We’ve created this seesaw scale activity to support the teaching of key topics within design and technology (D&T), maths, and science as part of the primary national curriculum at key stage 2 (KS2). You can use it as a one-off activity or link it with a measurement activity in food technology. Activity: Making the lever Learners will make a simple lever assembly from a binder clip, ruler, two paper cups and sticky tape. Children will also be asked to use a lever to work out the force required to move a load. Learners will compare results and explain their findings. Depending on available resources, this activity could be carried out individually or in small teams. Tools/supplies needed: Rulers Large binder clips Paper cups Sticky tape Weights such as steel nuts, small weights from science or marbles The engineering context Engineers use their understanding of how the effort applied to a lever affects the load in designing a wide range of products. From weighing scales to control pedals in cars, nutcrackers, wheelbarrows, bottle openers, and scissors, levers find their application across various industries. By understanding the seesaw lever class, learners will gain a fundamental insight into the principles that govern these everyday objects. Suggested learning outcomes Through this activity, learners will gain the ability to identify the parts of a lever and understand how the effort applied to a lever affects the load. They’ll also understand the principle of balance in a seesaw lever and how distance from the fulcrum impacts the effort needed to move a load. This will equip them with the foundational knowledge about levers, a key component in KS2 science, and provide a practical context for understanding mathematical concepts like multiplication and equality.

What affects the properties of the material in a cast product? In this activity students will explore how changing the ratio of PVA glue to PoP (plaster of Paris) affects the strength of a composite material. They’ll test both tensile and compression strength to find the perfect mix. This activity is part of a series of resources designed to challenge the students by requiring them to apply the knowledge and understanding of engineering materials through a ‘batch’ production experience, including CAD design project , Investigating batch production, and Engineering design processes. It’s one of a set of resources developed to aid the teaching of the secondary national curriculum, particularly KS3, supporting the teaching in engineering and design and technology (D&T). Activity: What affects the properties of the material in a cast product? In this activity students will investigate how the proportion of PVA glue added to plaster of Paris (PoP) affects the properties of the material produced in a cast product. Students will work in pairs to create card moulds. They will then mix different ratios of PVA, PoP, and water, pouring each mixture into duplicate moulds. After the test strips dry overnight, they’ll conduct two types of strength tests: a tensile test (hanging weights) and a compression test (using a G-clamp). They’ll then be tasked with analysing the results to determine how PVA affects the material’s strength. Look for patterns and identify the optimal ratio of PVA to PoP. Finally, decide on the best ratio for your future casting projects and present your findings to the class, using graphs or tables to support your conclusions. Download our activity overview for a detailed lesson plan on CAD design. The engineering context As part of the production process, engineers and designers must test the properties of different materials in order to select the best materials for their products to ensure that they’re suitable (e.g., are they strong enough for the activity that they’ll be used for?). Suggested learning outcomes Students will be able to explain how to develop a product or material to improve the outcome (engineering materials). They’ll also learn how to set up an experiment that allows key decisions to be made from the outcome. Finally, they’ll be able to carry out a manufacturing and testing programme, understanding the importance of time allowance and quality control.
