Producing a plan view will help children to develop drawing skills, while also introducing concepts such as dimensions, proportion, and scale. All through our fun, hand-on maths activity! Different types of drawing are used to communicate different types of information. Plan views see a section of an object as projected on a horizontal plane. In effect, a plan view is a 2D section drawing viewed from the top – this is different from a top view, which would see all of the features looking down from above. In the case of a room, for example, a plan view may show tabletops, chairs, doors etc., whereas a top view would also show the legs of the tables, light fittings etc. Plan views are widely used to show rooms or buildings from above. They may include measurements, furniture, appliances, or anything else necessary to the purpose of the plan. Plan views may be used to see how furniture will fit in a room, for example when designing a new kitchen, to show the builders the layout of a new building, or on estate agent’s literature to give potential buyers an indication of what a house is like. The lesson will help learners pick up an understanding of the practical uses of these drawings, from planning the layout of a room to presenting quite complex information about buildings. This is one of a set of resources developed to support the teaching of the primary national curriculum, particularly key stage two (KS2). It has been designed to support the delivery of key topics within maths and design and technology (DT). This could be used as a one-off activity, an extension to maths learning on scale, or linked to other school activities, such as preparing a map for parents evening. The engineering context Designers, engineers, and architects need to be able to communicate the details and features of rooms or products to other engineers, manufacturers, and users. This can include sizes, assembly instructions and layouts. Drawings are typically one of the main methods used for explaining this information – they can be found in every area of engineering and manufacturing. Suggested learning outcomes Children will learn about the purpose of a plan view drawing and be able to create one for themselves. They will also learn how to use dimensions and scale when drawing.

In this activity students will use case studies to investigate how architectural and building issues can be resolved. It can accompany our Structural engineering starter and How to design a spaghetti roof structure activities as part of a series of activities that explores structural engineering. 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 design and technology (D&T) and engineering. Activity: Exploring how architectural and building issues can be resolved through real-life case studies Students will view the design of the O2 arena by watching our Sound design video. They will also investigate the design of Stanstead Airport by viewing our structural engineering presentation. They will look specifically at the requirements of the buildings and the constraints in terms of structural design. They will also explore the design solutions used to overcome potential issues. This will form the stimulus for students to investigate structures in detail. The students will then be asked to explore possible solutions to a given structural design challenges. Download our activity overview for a detailed lesson plan on structural engineering for free! The engineering context Iconic structures don’t just happen by accident. When designing large buildings, there will often be challenges that need problem solving such as eliminating columns for large open spaces. Engineers need structural knowledge to be able to create innovative designs that are safe, functional, and aesthetic. Suggested learning outcomes Students will learn how to identify the key features of structural components. They’ll also know how to identify the various pressures a structural element can undergo and then apply their knowledge of structure to design an effective solution to overcome specific issues.

Assessing the probability of a particular situation occurring in a power station In this lesson students will use event tree analysis to roleplay an exercise where they quantify the risk of safety systems failing in a power station. 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 mathematics. In this activity, students will roleplay the following scenario: ‘A power station experiences a loss of coolant to its reactor about once per year. To prevent a dangerous explosion, a set of controls are in place. Firstly, an alarm which alerts the operator, this works on 99% of occasions. If this does fail various other systems will become operational to monitor the issue and prevent disaster.’ Using the examples in our Power station event analysis handout and Event analysis presentation, students will learn how event tree analysis can be used to model the probability of the risk of safety systems failing. Students can also use our Event analysis simulator tree spreadsheet to run simulations to check their workings. Download our activity overview for a detailed lesson plan (including answers) for teaching students about event tree analysis. The engineering context Event trees allow engineers to visualise the chain of events that could lead to system failures. Analysing the probabilities of these events helps them understand the likelihood of various outcomes as part of their efforts to design measures that can help to mitigate risks. Suggested learning outcomes In this lesson, students will learn about frequency trees, probability, and relative frequency.

Analyse an existing personal alarm system This is one of a series of resources to support the use of the BBC micro:bit in Design and Technology lessons. Schools are busy environments and it is easy for learner’s bags to be left unattended, taken by mistake or even stolen. Alarm systems using embedded electronics and programmable components can be developed to protect the property of learners during the school day. In this unit of learning, learners will research, program and develop a working school bag alarm system using the BBC micro:bit. Activity info, teachers’ notes and curriculum links In this activity, learners will carry out an analysis of an existing, commercially available personal alarm system.

In this activity students will learn about hypotheses by looking at heart rate data and how the use of computer games affects fitness. This lesson follows our Wii Fitness activity, which provides students with an opportunity to collect fitness data which they can use as evidence to debate whether people should be encouraged to engage in computer-based sport activities. 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 mathematics and science. Activity: Making hypotheses on how the use of computer games affects fitness In this activity students will review their results from our Wii Fitness investigation to form a hypothesis on how different activities affect heart rates. Students must consider the validity and size of the data set collected and work through a series of questions to explore if the data is sufficient to confirm their initial hypotheses. Download our activity overview for a starter lesson plan on hypotheses for free! The engineering context Engineering often involves problem-solving, and hypothesis based on initial observations can help engineers quickly define the potential cause of a problem. Hypothesis helps engineers to interpret data and can even guide them towards designing tests to make sure that the correct data is being gathered. This systematic approach can help to quickly validate or refute hypothesis, allowing engineers to find the right solution for the problem at hand. Suggested learning outcomes Students will be introduced to hypotheses and know how to create one from using a data set. They’ll also be able to evaluate the suitability and validity of the data collected as well as explain how results and ideas can be changed when we consider other variables.
