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.

Explore maths with gingerbread men, and find out how many combinations of buttons are possibilities. This is a simple maths game for KS1 and KS2 mathematics, as a curriculum mapped activity to do at school or home. This activity in partnership with MEI is a ‘finding all possibilities’ type of problem. It encourages children to work systematically to ensure they know when all the solutions have been found, as well as ensuring they haven’t made any two gingerbread men look exactly the same. A strategy that will be promoted is the idea of fixing one of the variables, in this case one of the buttons, whilst changing the others in turn. To ensure they become confident talking about their maths, ask the children to work in pairs if possible in a classroom or at home. All activity sheets and supporting resources are free to download, and all the documents are fully editable, so you can tailor them to your students’ and your schools’ needs.

Discussing how engineering can support urban growth This activity provides a quick, engaging introduction to a lesson, focusing on the link between sewage and the underground tunnel system. It encourages students to think about the role of engineers in providing us with healthy sanitation and waste-water disposal systems. This is one of a set of resources developed to aid the teaching of the secondary national curriculum, particularly KS3, supporting the teaching in science, geography, engineering or design and technology (DT). Activity: Discussing how engineering can support urban growth Students will investigate sewage tunnels that are being built under London by first watching our Shifting sewage film. Students will then consider how society has changed over time, to identify the influences that have resulted in the needs for the new tunnel. Download our activity overview for a detailed lesson plan on the engineering challenges that come with population growth. The engineering context As cities like London grow, the need for expanded sanitation systems need to be considered for the removal of urban waste. This can present logistical challenges as there will often be an existing waste tunnel system, along with transport networks such as the London underground, causing complexity. Engineers will therefore need to carefully consider several factors for new engineering projects that support population growth including geology, environmental impact, available technology, local disruption (and the political considerations that come with that) along with the existing infrastructure. Suggested learning outcomes By the end of the lesson students will appreciate the issues around developing new tunnel systems in their location. Download our activity sheet for free!
