Carry out an experiment to measure how the light from a torch changes with the distance from a lamp In this activity learners will carry out an experiment to measure how the light from a torch changes with the distance from the lamp. They will record their results in a table and plot a graph. Activity: How Does the Light from a Torch Change with Distance? This is one of a set of resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within science, design and technology, and maths (in this case, mainly science). This resource focuses on the investigation of how the light from a torch (flashlight) changes with distance. This activity is designed to be carried out in small groups. It is recommended that the teacher carry out the activity in advance of the lesson, to determine whether the distances suggested give sufficient (or excessive) spread of the light image, as this will be determined by the design of the torch used. It is recommended that new batteries are used in the torch, as the light intensity may be affected by the amount of charge remaining in the batteries. This could be used as a one-off activity in science or linked to maths learning about tables and graphs. This activity will take approximately 40-60 minutes to complete. Tools/resources required Graph paper Masking tape Tape measures Torches/flashlights (with new batteries) Pencils (for extension) laser pointer (for extension) cut-out templates of simple shapes (e.g. square, triangle, circle), mounted on craft sticks The engineering context Engineers need to understand how light behaves when designing products for many practical applications. For example, when designing buildings, they may consider the provision of windows and artificial lighting; and when designing cars, they may consider the power and position of both internal and external lights and the placement of mirrors. Suggested learning outcomes By the end of this activity students will be able to carry out a scientific experiment and they will understand that the distribution of light from a torch changes with distance.

Making a device to measure wind speed In this science project, students will construct a Robinson Anemometer using common household materials. Once built, students can use it to measure wind speed either inside with domestic items or outside with the natural environment. This activity can serve as a stand-alone project or as a component of a broader unit on weather or measurement. It is intended for upper Key Stage 2 learners (years 5 and 6). This resource is part of a collection of free STEM resources created to aid in the teaching of the primary national curriculum, especially in the areas of science and design and technology. The purpose of this activity is to aid in teaching key concepts through the construction of a homemade anemometer. Parts and components required: Polystyrene balls, 25 - 40 mm diameter, 1 per anemometer Wood/bamboo skewers, 3 per anemometer Putty (such as Blutack or Whitetak) OR modelling clay (such as clay, Plasticine or Playdough). EITHER 6 paper cups OR 4 paper cups and a plastic water bottle with a sports cap Sticky tape Tools and equipment required: Fans, hair-dryers or other sources of moving air Stop watches Commercial anemometer (for extension activity) The Robinson Anemometer The Robinson Anemometer is a type of cup anemometer, an instrument used for measuring wind speed. It was invented by John Thomas Romney Robinson in 1846 and is named after him. The Robinson Anemometer consists of four hemispherical cups mounted at the end of horizontal arms, which are attached to a vertical shaft. As the cups rotate due to the force of the wind, the speed of the wind can be calculated based on the rate of rotation. The Robinson Anemometer is still widely used today and is considered one of the most accurate and reliable types of anemometers. The engineering context Engineers need to be able to measure the forces that will act on the things they need to design. They need to understand how these measurements are made so that they can be confident that their designs will meet the requirements in practical situations. Suggested learning outcomes By the end of this activity students will have an understanding of what is meant by wind, they will be able to construct a simple mechanical device and they will be able to understand that the linear movement of air can be measured by the rotation of an anemometer.

Exploring the movement of a human arm for robotics design This is an engaging starter activity in which students examine how human arms move. Learners will also discover how this movement can be replicated with a mechanical arm using a smart material. Students can then subsequently use this information to support the design of a robot arm. This lesson can be followed by 3D modelling, which looks at designing and modelling a 3D robot arm and build a robot arm, which looks at how to make a robot arm with carboard. It’s one of a set of resources developed to aid the teaching of the secondary national curriculum, particularly KS3, supporting the teaching in science (specifically biology), engineering and design & technology (D&T). Activity: Exploring the movement of a human arm for robotics design By examining the movement of their own arms, students will learn how robot arms might be designed and how smart materials can play a role. Students will first bend their arms and be asked to monitor and describe the mechanics involved (muscles, joints, etc.). They will then consider how this natural bending motion can inspire the design of robot arms. Learns will be introduced to shape memory alloy (SMA) springs, which can be deformed or stretched and then revert back to their original shape when heated (this can be achieved using an electrical current). Finally, students will be tasked with explaining how SMAs could be used to create movement in a robot arm. Download our activity overview for a detailed lesson plan on the movement of a human arm. The engineering context Robot arms are an example of a programmable system. They are used in a wide variety of industrial applications, ranging from assembling cars to spray-painting products. They’re also used in more dangerous applications for humans such as bomb disposal and repairing space craft as they orbit the earth. Suggested learning outcomes Students will learn that a human arm moves due to the contraction of muscles, and they’ll understand that a robot arm can also use contraction or rotation to achieve movement. Finally, they’ll learn that shape memory alloys can revert to a previous shape when heated. Download our activity sheet and related teaching resources for free!

Work out how to reach destinations using a scale map In our daily life we take 21st-century technology for granted. Some could argue that we aren’t developing basic skills, as technology often does the work for us. When the technology fails, however, the absence of some necessary skills could create difficult situations. Can your students use our worksheet and presentation to work out how to reach a destination from a scale map? This activity is an engaging investigation into the uses of communications technology in the modern world. There is an opportunity to audit the students’ skills such as visualisation or map-reading to form a scale drawing. These are skills that may not have been developed due to the use of various electronic devices. As a visualisation activity, distribute the Lost Now presentation as a handout or display it using a data projector. This is an activity where the process of thinking about what the map might show is more important than the actual outcome of the sketch they would produce. The handout has text handouts that can be printed and given to the students. There is also a map using Ordnance Survey symbols that might be better displayed on a screen using a data projector. Students should complete the three activities outlined in the presentation either in groups or as individuals. Tools/resources required Ruler (a transparent ruler showing millimetres is best) Calculators Students will need Ordnance Survey symbols from the website below (either print sheets of the symbols or display them on a screen to save on copying). The engineering context Living in a highly technological world, where access to information and entertainment is at our fingertips, the Inform and Entertain Me topic is a gateway to engage and introduce students to the principles and technology that form the basis for communication devices that are used in our everyday lives. Suggested learning outcomes By the end of this activity students will be able to make informed decisions about technology for social, economic and environmental reasons, they will be able to use scale drawing and they will have an understanding of how waves are used to carry a communications signal.

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.

This is a practical exercise in which students will utilise their mathematical knowledge to solve problems and apply formulas. Specifically, they will compute the length of pipes necessary for an underfloor heating system. They will also write a brief explanation of how a sustainable underfloor heating system operates. 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.
