In this design activity, students will produce a 3D model of a robot arm. It’s part of a series of activities that sees students designing and modelling the physical elements of a robot arm. This 3D modelling activity assumes that students have previously made a 2D model of a robot arm in the Build a robot arm activity (if they haven’t, they may benefit from trying the 2D modelling activity first!). This is one of a set of resources developed to aid the teaching of the secondary national curriculum, particularly KS3. It has been designed to support the delivery of key topics within design and technology (DT) and science. Activity: Designing and modelling a 3D robot arm In this hands-on activity, students will be divided into small teams and tasked with taking inspiration from their previously completed 2D models of a robot arm to construct a 3D model. This arm will then have to lift three identical objects between a “start” and “end” location. The arms will be judged on how accurately the items are transferred, the lack of damage to the items being moved, and the time needed to complete the moves. Students will need consider factors such as grip, hand operation, item protection, and structural rigidity (i.e., how do they stop the arm from bending?). Teams will have the opportunity to test, improve, and refine their designs based on constructive feedback provided by the class. The engineering context Understanding how to design and build a robotic arm will introduce your students to key concepts in mechanical engineering and automation technology. Robot arms are used in a wide variety of industrial applications, ranging from loading machines to assembling cars, welding parts together and spray-painting products. They are also used in delicate applications such as bomb disposal and repairing space craft while in orbit. Suggested learning outcomes By the end of the lesson students will be able to design and build a 3D model. They will also have developed their creative and problem-solving skills, teamwork abilities and a practical understanding of the workings of robot arms. Download our activity sheet for free!

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.

Learn about train design and improve engineering skills with this fun STEM activity! In this activity students will design a model high-speed vacuum tube train. Students will have to decide on how to get a ball to travel through a tube as quickly as possible without the help of gravity. They will then look at the forces that would act on a real vacuum tube train. Students should be supplied with a variety of marbles and ball bearings in various sizes. They should be allowed to choose which sizes they want (this will depend on the method they choose). Options may include using a magnet to pull the ball, using force from a metal rod or air from a pump to push it. Learners can’t rely on gravity – the tubing needs to be placed on a level desk or floor. Groups are asked to record the speed and then modify their design to make it faster. They will need to use stop clocks to measure time and then calculate speed. If you have data-loggers to measure speed these can be used instead. Students should understand the need for repeating their measurements and they should record them in a table. Groups can modify the ball if they wish. They might want to make it more aerodynamic by using paper or by using a lubricant. As an optional extension, students could modify their design so it has a safe stopping mechanism. Alternatively, students could write an explanation as to why air resistance is not a problem in a vacuum tube train and why this is an advantage. How long will this activity take? This activity will take approximately 50 minutes to complete. What is a vacuum tube train? A vacuum tube train, also known as a vactrain, is a proposed design for train transportation. The train would use maglev technology to run in partly evacuated tubes or tunnels. Reduced air resistance could allow vacuum tube trains to travel at very high speeds – up to 4,000 mph! Suggested learning outcomes By the end of this activity students will be able to design a model vacuum tube train and they will be able to use a force diagram to show the forces interacting on a real vacuum tube train.
