This can be effectively taught within mathematics or within design and technology, as part of resistant materials or product design. How long will this activity take? This activity will take approximately 60-90 minutes to complete Tools/resources required Green School film Projector/Whiteboard Measuring equipment e.g. tape measures or trundle wheels Squared paper The engineering context Sustainability is a key consideration in modern engineering practices. As the world faces pressing environmental challenges such as climate change and resource depletion, engineers must design solutions that not only meet the needs of society, but also minimise their impact on the planet. Sustainable engineering involves developing systems, products and processes that are socially, economically, and environmentally responsible. This can include reducing carbon emissions, optimising energy use, minimising waste, conserving natural resources, and designing products that can be recycled or repurposed at the end of their lifecycle. Suggested learning outcomes By the end of this activity students will be able to describe the operation of a sustainable underfloor heating system and they will be able to create and apply mathematical formulae in a practical context.

Time the journeys of different shaped boats and present the results This engaging engineering activity for KS3 considers displaying data from a practical investigation looking at the effect of streamlining a boats hull. Students will be asked to consider how this information can be represented effectively and use this to form conclusions. The reliability of their results will then be discussed. Activity Measuring boat speed Students will use the test rig, which can be found in the resources below, to test several different shaped boats. Students should measure the time taken for each boat to travel a set distance and record the results. Ask the students to discuss the fact that there is no measurable independent variable as it is very difficult to quantify the hull shape in terms of numbers. The students should ponder how they are going to represent these results graphically. If time is available, complete the investigation by repeating the tests. Discuss the sorts of errors that might occur in the collection of results. Learners will then plot their results into a bar graph. This could be used as part of an advertising campaign to sell the boat which could include design, bar chart, a brief conclusion and an explanation as to why the results are reliable. There is also an opportunity to use data logging equipment as well as light gates to further reduce errors in this engineering activity. As an extension, students could calculate speed (s=d/t), and the mean speed for each boat, taking into account the anomalous results. Students could consider what they could measure to draw a line graph and find the optimal hull design. If time is available, students could manufacture and test their own designs and include them within the analysis. This activity will take approximately 45 minutes. Tools/resources required The construction is a fairly simple activity and can be undertaken by your KS3 students (as an after school activity or by a technician) Boat objects Stop Watch Graph Paper Suggested learning outcomes By the end of this activity students will be able to explain when to use a bar chart and when they should be used to display categoric variables, they will be able to evaluate an experiment in terms of its reliability and precision and they will be able to apply scientific and mathematical understanding to an engineering context.

Identifying which materials might offer the best prospects for a financial investment In this activity, students will investigate the properties of different types of smart materials and decide which ones might offer the best prospects for financial investment. The development of new materials with incredible properties is changing the way we live. From 4K TVs to super light airliners, these materials have quickly found their way into the modern technology around us. One area where modern materials have made a huge impact is in the development of prosthetic devices. Some of these devices are beginning to outperform ‘natural’ body parts.

Learn about sound waves in this free STEM with this free lesson plan for KS3 From founding communications, such as the fire beacon, to being able to communicate with space, there is no denying that developments in communication have advanced at a rapid speed. This topic presents students with communications of the past, present and future, helping them to understand the principles that form the basis for these developments. This engaging STEM activity is aimed at KS3 students and deals with how animals use sounds and how sounds change in natural phenomena. This is so that a student can understand how sound waves travel. The teacher will first distribute a copy of the ‘Animal Sounds’ handout, which can be downloaded below, to each student. Make sure students understand sound is a longitudinal wave of compressions and rarefactions of the material. Soundwaves follow the laws of wave behaviour, so they are a useful introduction to wave properties. This activity can be simplified (particularly for less able students) by creating a discussion on why different animals have different hearing ranges and their experience of phenomena such as the Doppler effect. Use the handout to discuss different sounds and what they might have learned in other lessons (e.g. music) about pitch, frequency, amplitude etc. As an extension students could produce a display from low to high frequency, showing where the sound ranges used by different animals lie. Students could consider how sounds outside the normal spectrum could be used to develop new products. For example, to make ‘silent’ devices to broadcast sound or data between two points. This is a quick and simple activity that will take approximately 15 minutes. Tools/resources required Calculators The engineering context Sounds are vibrations travelling through materials. Many animals make sounds, either for communication or for location. Sound travels at different speeds in different materials. Generally, the denser the material, the faster the sound will travel. Sound is a longitudinal wave of compressions and rarefactions of the material (a rarefaction involves particles in the material being more spread out than usual). Sound waves follow the laws of wave behaviour, so they are a useful introduction to wave properties. Suggested learning outcomes By the end of this free resource students will know that sound is produced by objects vibrating and they will understand that sound is a longitudinal wave. They will also know about the range of frequencies that can be heard by humans and other animals and they will understand that sound travels at different speeds in different mediums.
