What is sustainable energy? What is a carbon footprint? The “Energy Efficiency” curriculum explores the meaning of these terms and encourages students to research what they can do as a school community to save energy and reduce their carbon footprint. The activities use the example of Howe Dell Primary School, which was designed with the principle of sustainability. This provides a framework for students to compare their own school and identify simple energy-saving measures that they can implement to reduce their carbon footprint and save money. By studying Howe Dell Primary School, students can see how cutting-edge technology and science are being used to achieve sustainability goals. Activity overview Show the students the Green School film. Ask them to briefly discuss, as a class, the following questions: What do we mean by “sustainable energy” resources? What types of sustainable energy resources are found in buildings today? What does “carbon footprint” mean, and how is it calculated? What is sustainable energy? Sustainable energy is energy that meets the needs of the present without compromising the ability of future generations to meet their own needs. It is energy from renewable sources that do not produce greenhouse gases or other pollutants. Sustainable energy is important for a number of reasons. It helps to reduce our reliance on fossil fuels, which are a finite resource and produce greenhouse gases that contribute to climate change. It also helps to improve air quality and create jobs in the clean energy sector. What is a carbon footprint? A carbon footprint is the total amount of greenhouse gases emitted by an individual, organisation, event, or product. Greenhouse gases trap heat in the atmosphere, which contributes to climate change. A carbon footprint can be calculated for any activity or entity. There are several different methods for calculating carbon footprints. They all involve measuring the amount of greenhouse gases emitted during a product or service’s production, transportation, use, and disposal. Suggested learning outcomes By the end of this activity, students will be able to explain what “sustainable energy” and “carbon footprint” mean, and they will be able to describe and explain what sustainable technologies could be used in their school.

**In this fun activity for kids, students will construct a miniature catapult capable of firing a marshmallow! ** This exercise will allow students to develop practical skills using a saw and a glue gun and their communication skills as they work as part of a team. This activity could be used in Key Stage 2 as a straightforward design and technology project. It could also be integrated with history and drama. This activity will take approximately 100-180 minutes to complete. Tools/resources required For the marshmallow holders: Copies of the marshmallow catapults holder (handout) printed on card Scissors Glue sticks For the catapult structures: Square section softwood: 8 x 8 x 590 mm, 6 pieces per team plus spares Saws Vices, bench hooks, mitre boxes or similar devices to secure the wood when cutting Glue guns (one per team) 2 elastic bands per team (one small, one large) plus spares For testing: A bag of marshmallows Optional: Copies of the marshmallow catapults structures (handout) printed on paper Sandpaper Baseboards or A3/A4 pieces of cardboard for use as baseboards when using glue guns The engineering context Did you know that the word ‘engineer’ was initially used to describe people responsible for building siege weapons in ancient times? During the sieges of towns and castles, it was customary for skilled experts to construct catapults to breach defences and demoralise the defenders. Among the various catapult types, one was known as the ‘onager’, named after a wild donkey renowned for its fierce kick. The individuals responsible for building this particular catapult were referred to as ‘onager-neers’, a term that eventually evolved into engineers. Catapults need to have a structure which is both strong and stiff. Otherwise, the forces they experience when used can cause them to break. A catapult made from square shapes can be made significantly more rigid and less likely to collapse by adding reinforcement to form triangles. The principle is still widely used in civil engineering for structures ranging from cranes to aircraft structures and the roofs of buildings. Suggested learning outcomes By the end of this activity, students will be able to understand that triangles can be used to reinforce structures, they will be able to safely operate a saw to cut wood, safely use a glue gun, and they will be able to design and make a structure.

Developing a new design for earphones and headphones In this activity, students will develop a new design for earphones and headphones using reverse engineering. The activity will also teach the importance of fitness for purpose when designing new products. It is essential that products used in our everyday lives are fit for purpose. In order to design a product which will be useful to the customer it is important to understand how different products function and why different materials and components are suitable for different applications. This is one of a set of resources developed to aid the teaching of the secondary national curriculum, particularly KS3, supporting the teaching in design and technology (DT). It can be used as a starter activity to be followed by our Materials for design lesson. Activity: Developing a new design for earphones and headphones Students will answer a series of questions provided in our worksheet and focus on identifying the target audience for each of these designs, evaluating technology and style, and exploring the balance between form and function. They will also take part in a discussion that relates the design changes to societal and technological advancements and then use what they’ve learned to produce a design of their own, focusing on areas where they’d develop existing technology. The engineering context Engineers might reverse engineer a competitor’s product to understand its strengths, weaknesses, and how it compares to their own offerings. This can help them improve their own designs or develop innovative new features. Sometimes engineers will have to do this using just photographic or video evidence. For example, Ferrari and Mercedes F1 engineers might want to learn how a rival racing team like Red Bull have built their car but they will not be able to closely examine the car itself. They will have to rely on visual evidence for their reverse engineering analysis. It’s important to remember that there are ethical implications related to copying and intellectual property, and therefore reverse engineering should only be used for inspiration and to improve your existing understanding of a particular piece of technology. Suggested learning outcomes At the end of this lesson students will understand the construction and function of an engineered product or system for the purposes of reverse engineering.

It is designed to challenge the students by requiring them to apply the knowledge and understanding of engineering materials through a ‘batch’ production experience. This is one of a set of resources developed to aid the teaching of the secondary national curriculum, particularly KS3, supporting the teaching in design and technology (DT). Activity: Understanding the concept of modular design and the casting process The lesson includes two short tasks to support students’ understanding of the application of the casting process and the concept of modular (repeat) design. Firstly, students will view the Cast Products presentation for an introduction to casting as a manufacturing method. By looking at each of the products that have been casted students will explore the advantages of casting (e.g., creating complex shapes, standardisation, batch production, fine detail quality, etc). Next, students will view the Modular Products presentation to identify the common characteristics of these products. The engineering context Engineers not only need to consider the properties of smart materials, they also need to think about the best way to use these materials within manufacturing so that they can be mass produced in an economical way. The casting process offers a way to use smart materials like D30 to mass-produce all sorts of goods cost-effectively. The material is particularly advantageous because of its shock absorption properties and can be used for the creation of snowboards and other sporting goods, along with safety gear such as helmets and limb protectors. It can even be used with phones and other devices that benefit from being built with impact protection in mind. Suggested learning outcomes By the end of the lesson students will know how to describe the characteristics of a cast product. They’ll also be able to explain why a designer may use a repeating module.

As an optional extension, students could use the internet to research extra information on their transport systems. They could then use this information to produce a detailed presentation on how the transport system works. This could be a poster or a computer presentation. Teams will need access to the internet to complete this activity. If possible, put the handout on the shared system so teams can access them through their computer. This allows them to use the hyperlink to the website for research. They can type their answers into the grid directly or print out the sheet and write on them. This activity will take approximately 50 minutes to complete. Tools/resources required Computers with internet access Suggested learning outcomes By the end of this activity students will be able to use ICT to research an existing or possible future community transport and they will be able to use criteria to judge how well it fulfils social, environmental, and economic needs. All activity sheets, worksheets 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. The activity sheet includes teacher notes, guidance, useful web links, and links (where appropriate) to the national curriculum in each of the four devolved UK nations; England, Northern Ireland, Scotland and Wales.

**This activity gets students to use their knowledge of electromagnetism in order to design and build a magnetic tool holder for a surgical robot. ** Students learn how simple scientific principles can be used in sophisticated applications, how electric circuits can be switched on and off, and the factors that can affect the strength of an electromagnet. Activity introduction Each group is a dedicated design team with a compelling mission – to craft a comprehensive outline design for a tool holder tailored to seamlessly integrate with a surgical robot’s arm. The task at hand: • Each surgical tool boasts a magnetic fitting, necessitating the utilisation of an electromagnet within the tool holder to ensure a secure grip. • A dynamic approach is required considering the diverse range of sizes and weights among these tools; This entails varying the electromagnet’s strength to account for this. Guided by these challenges, teams will brainstorm, innovate, and collaborate to present their inventive solutions in a concise one-minute presentation to the rest of the class and assessed according to the success criteria on the design brief. The engineering context Telemedicine employs contemporary communication technology to provide medical diagnoses and patient care, even when the physician and patient are geographically separate. Remote surgery entails utilising robotic systems within the operating room to aid surgeons during procedures. The surgeon observes the patient through a terminal and controls robotic surgical instruments using a specialised console. Suggested learning outcomes Upon completion of this activity, students will gain an understanding of the capabilities of surgical robots. They will grasp the transformation of basic scientific principles into intricate applications, comprehend the functioning of electric circuits’ activation and deactivation, and discern the variables impacting the strength of an electromagnet.

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.
