Design investigations to test reaction times and ability to concentrate whilst driving In this activity students will design and carry out investigations to test reaction times and ability to concentrate. They will then try their test on older people and use their results to design a car of the future. Students will first be asked to discuss the opinion that road accidents are more likely to be caused by younger drivers. Make sure the students realise that this is an opinion and is not backed up with evidence. They could be asked how this opinion could be proved or disproved. Many different personal attributes can impact road safety, including a person’s vision, ability to concentrate, reaction times and mobility. The car of the future should be designed to help people overcome these issues. Students will carry out some tests in the classroom to give a reflection of how safe they would be as a driver. Students will work in groups of around 3-4 to plan and carry out their tests. They will gather data and state what it shows. Graphs can be drawn if there is time. For homework, students can repeat their experiment at home with older members of their family. In the following lesson, ask students to share their results with the rest of the group and discuss as a class what their results show. Are reaction times quicker in older or younger people? Which age group is less likely to get distracted? Tools/resources required Class access to computers with internet connection and headphones Paper/pens Rulers Projector Whiteboard The engineering context Understanding basic safety concepts is essential for engineers in the automotive industry. Suggested learning outcomes By the end of this activity students will be able to plan an investigation, deciding what measurements to take and what equipment to use, they will be able to choose how to present results and they will be able to use data to inform design. 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.

Discuss safety issues in personal transport and analyse data to work out which form of personal transport is currently the least safe Personal transport is becoming safer as technological advancements are made and more and more safety features are designed. In this fun STEM activity students will consider what safety features are in use today. Students will first name some personal transport methods, including those they use. In pairs they can discuss any safety features of these methods, why they are important and then they will rank the transport systems in order of how safe they think they are. The ‘Safety statistics A’ handout includes a chart which shows the proportion of reported road casualties by road user type and severity in Great Britain in 2012. The students will then interpret the data and write down what it shows. They can then compare this to the ranking they did in the discussion earlier. The handout shows that car occupants and pedestrians are the most common types of road casualties. How do you think safety can by improved for car occupants and pedestrians? Ask the students to think about what safety measures already exist and then ask them to think about what features cars should have in the future. This engaging activity that is the perfect way for KS3 students to develop their critical thinking skills. How long will this activity take? Approximately 30-59 minutes to complete. The engineering context Car and road safety engineers are professionals who are responsible for designing and developing vehicles and road systems that are safe for drivers, passengers, and pedestrians.

Learn about the technology behind satellite navigation systems and discuss the pros and cons of using them Can your students consider how a GPS system functions and discuss the advantages and disadvantages of using them? This activity is suitable for KS3 and KS4 and encourages students to undertake research and produce a visual display. This activity is an engaging investigation into the uses of communication technology in the modern world. This activity is an individual activity and could be run in an ICT suite to allow students to use the internet for research. Distribute the Sat Nav handout to students. This handout gives some outline information about satellites and an un-annotated diagram. Students can cut out or copy the un-annotated diagram and add information to this to produce a visual display of how a Sat Nav system works. There are a series of questions on the Sat Nav handout. Questions 1-4 are designed to get students to undertake research on the topic of satellites and their functionalities and capabilities. This is a simple activity that will take approximately 30 minutes to complete. How does a Sat Nav system work? What we often refer to as ‘Sat Nav’ is properly called the Global Positioning System (GPS). This uses satellites that continually transmit a signal. They are like an accurate orbiting clock. The signal from at least three and up to seven satellites is received and compared by the Sat Nav device. Using some complicated maths, the Sat Nav device can work out not only where it is on the Earth’s surface, but at what altitude it is as well. The position information is compared with a map downloaded and stored by the Sat Nav device. The satellites tell you where you are, and the mapping hardware fills in the pictures of the road around you. The satellites need to have a clear path through the air to the Sat Nav device – this is normally called a clear line of ‘sight’.

Structured class debate on the location of a new wind farm There is much debate about the issues created by carbon emissions and how renewable energy sources can help resolve these challenges. Most people agree that renewable energy is a good thing, but many oppose to having wind turbines built near their neighbourhood. In this role-play activity, participants take on different roles to debate a proposed wind farm. In pairs, students discuss whether their character would be in favour of the proposed wind farm and prepare a two-minute talk to share their case with the group. Afterwards, divide the larger groups into ‘for’ and ‘against’ and bring together all the individual statements to form a strong, coherent case. Four people are chosen to give two reasons to support their argument. Activity info, teachers’ notes and curriculum links This activity has been written with a strong science bias. However, it can easily be taught in design and technology with either a systems and control approach or from a ‘sustainability’ angle, looking at the topic of wind farms and the future of energy production. The ‘sustainability’ perspective will provide an activity that could involve design and technology, geography and citizenship. Download the activity sheets for free!

How sounds travel as waves of different frequencies and wavelengths 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 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. 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.

Designing a questionnaire that informs product design Engineers play a key role in our everyday lives, often in ways we may not realise. Take the Watt Nightclub in Rotterdam as an example - engineers have designed a system that turns the energy created by dancing into power for the lighting. Even the colour of the lights was a consideration. In this activity, students will explore the relationship between colour and mood, and how it might impact the amount of electricity generated on a dance floor. This is one of a set of resources developed to aid the class teaching of the secondary national curriculum, particularly KS3. It has been designed to support the delivery of key topics within maths, science and design and technology (DT). Activity: The activity begins with a class discussion on whether colour can scientifically affect mood. Students will then learn about the role of questionnaires in research, including what makes a good questionnaire and what factors need to be considered when designing one. The class will watch the Dance Power film, which directly relates to this technology, and then split into groups to create their own questionnaires. These will be tested, evaluated, and refined before being conducted as homework. Students will process and present their findings, considering the reliability and accuracy of their evidence. They’ll discuss their results and the effectiveness of questionnaires as a research tool. The engineering context Market research is essential for engineers working in product design, providing valuable insights into consumer needs and preferences, enabling them to create innovative products that meet market demand and improve user satisfaction. Furthermore, by exploring how engineers can use colour to influence mood and hence energy production, students will gain an insight into the creativity and problem-solving involved in engineering. Suggested learning outcomes Through this activity, students will gain an understanding of the scientific method, specifically the design and implementation of a market research questionnaire. The class will develop the ability to generate scientific evidence to prove a hypothesis, in this case, the relationship between colour and mood. They will also consider what constitutes sufficient evidence for scientists to confirm a hypothesis. Download our activity sheets for free!

In this engaging maths activity, students will embark on a journey of discovery and creativity as they explore the mesmerising art of tessellation. This activity is designed for KS3 students and involves formulating a rule that can be used to create tessellation patterns. It will help students develop an understanding of the tessellation that will be required to design interlocking units. This lesson plan could be taught in maths or as part of graphics within design and technology. This activity promises an exciting blend of hands-on exploration, critical thinking, and geometry, fostering a deeper appreciation for the captivating world of tessellations. What is tessellation? Tessellation is a geometric concept in mathematics and art that involves covering a surface with repeated, non-overlapping shapes. These shapes, called tiles or polygons, fit together seamlessly, creating a pattern extending infinitely across a surface. Tessellations can be found in various forms in nature, art, and architecture. The most famous example of a tessellating shape is the regular hexagon, which can fit together perfectly to cover a plane without leaving any gaps or overlaps. Other common tessellating shapes include squares, triangles, and other regular polygons. The engineering context The ‘Engineering Process’ scheme of work gives students an in-depth understanding of some engineering materials and how they are being developed in industry. This scheme was inspired by the casting process used to make the D3O smart material into a ‘usable’ form; this links to industrial practices such as quality control, standardisation, and casting manufacture. It is designed to challenge the students by requiring them to apply their knowledge and understanding of engineering materials through a ‘batch’ production experience.
