Use mathematical calculations to decide whether it is worth switching to an alternative fuel Can data be used to determine whether it is worth converting to LPG? This activity will encourage students to use their problem-solving skills. Understanding what information is needed and how to use the information is a key part of problem solving. Download our free fuel consumption worksheet below to take part in this engaging activity. This is a great way for GCSE students to learn about fuel efficiency and develop their problem-solving skills. Students should to read the problem on the first slide of the presentation. Let them think about what criteria they can use to decide whether it’s worth converting to LPG. They should take into account the annual mileage, price of petrol or LPG at the local station and size of the car in question. They should consider the amount of money saved by converting vs the cost of the conversion. Some students may want to examine the time it would take to recover the cost of converting the car. They also need to be aware that “a car uses 10% more LPG than petrol when driving the same distance.” Discussion points Encourage discussion about which type of car saves most and get them to think about why this is. Remember they all do the same annual mileage! If students don’t consider recovering the cost of conversion, then prompt them at some point. Extending the problem It is possible to use the spreadsheet to produce a graph showing how the savings vary with annual mileage. Students could investigate the fluctuations in LPG and petrol prices over time to see if this would influence their decision. Potential GCSE content covered In this activity learners will use and apply calculations, use compound measures, calculate the percentage of an amount and consider the application of algebra to spreadsheets. What is LPG? LPG is a by-product of crude oil extraction and the refining process. Many people who consider LPG as an alternative to petrol do so because they believe that the combustion of propane results in lower carbon dioxide emissions. In terms of fuel costs, LPG costs a little more than half the price of petrol or diesel, but fuel economy is about 20-25% lower. Therefore, the overall running costs of an LPG car is approximately a third less than a petrol only car – but only once you’ve recovered the cost of the conversion.

Decide on a systematic way to estimate the number of objects in an image In this engaging STEM activity, designed for secondary school students, learners will take images from the Hubble telescope and use them to estimate the number of stars contained in those images. Activity: Counting stars using estimation The first slide in the presentation below introduces students to the context of the challenge and pushes them to think about how mathematics can be used to solve a real-life problem. The second slide asks the students to estimate the number of stars in the image. A Geogebra file “counting stars” which subdivides the enlarged image into smaller grids for sampling has been supplied. Students will need to find a systematic way of estimating the number of objects in the enlarged image. One approach is to subdivide the enlarged image into smaller sections, count some of these and work out the mean. This mean can then be taken as the number of objects per subsection and multiplied by the number of subsections to get an estimate of the number of objects in the enlarged image. To obtain an estimate for the number of stars in the original image, this figure then needs to be multiplied by the number of enlarged images in the original image. Students will need to consider when to round off and what degree of accuracy is appropriate. Discussion points Comparing the different estimates obtained by the students would be interesting. Looking at the differences in their estimates for the number of objects in the enlarged image first and then observing how this transferred to the differences in the original image. Extending the problem This method is used in a wide variety of contexts, from estimating the number of hairs on someone’s head to auditing the number of insects in an enclosure at a zoo. This activity could be extended by looking at capture/recapture as a method of estimating animal populations. Potential GCSE content covered In this activity students will cover mean average, rounding and accuracy and reasoning from calculations.

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’.

Through this fun and engaging STEM activity, learners will understand how aerodynamic and streamlined shapes are used in our day to day lives and the design, technology, and engineering principles behind them. This is a free resource aimed at secondary school children. Students will have the opportunity to learn about aerodynamic forces and aerodynamic design and how these design principles enhance speed and efficiency in a product. A brilliant engineering activity for kids. Students will start to understand the basic principles of aerodynamics by looking at familiar products that have been designed with ‘speed’ in mind and through identifying features common to these products. Later, they could start to explore the requirements of aerodynamic design through testing simple shapes in a wind tunnel and through water. The activity focuses on students acquiring an understanding of aerodynamics through testing, experimenting, and developing. This activity is designed to be taught through science and design and technology simultaneously, as a cross-curricular project. However, it can also be tackled independently from each subject. What do the images have in common? Why have they been designed in that shape? Could they be split into themed groups? As an extension students could be asked to consider the social/economic and technological benefits (and drawbacks) of each example. This will give some reasoning behind the development of the final design and illustrate how there are many different factors affecting the design. The engineering context Aerodynamics refers to the way air moves around things. Anything that moves through the air reacts to aerodynamics. Aerodynamics acts on aeroplanes, rockets, kites and even cars! Suggested learning outcomes By the end of this activity students will be able to identify areas where aerodynamics is used in real life and they will be able to describe the social/economic and technological effect of the work.

Queuing theory is a mathematical discipline that helps us understand the behaviour of queues and make predictions about their performance. It considers various factors such as arrival rates, service times, and queue lengths to analyse and optimise queuing systems. By applying queuing theory principles, students will learn how to evaluate different queues and determine which will likely offer a shorter waiting time. Through this activity, you will develop your analytical and problem-solving skills and gain a deeper understanding of queuing theory concepts. You will also learn how to apply these principles in real-life situations, making you a proficient queue navigator in the future! Activity In this activity, students will be presented with two different systems of queues. They should think about the benefits and problems with each system. Encourage the students to think about how they can compare the two systems. What figures could they calculate? What diagrams would help to provide a picture of the advantages and disadvantages of each system? Give the students time to find/calculate their figures and then ask them to present their case. This task provides an opportunity to discuss the most appropriate average. The mean time for the first system is affected by longer wait times for a few customers. Would the mode time be a better average, as this is the most frequent experience, or is the median better? The engineering context Queuing theory is an area of maths which has many applications. When you log onto the internet, you join a queue for a server. Computer engineers and systems designers study queues to help them make systems work more efficiently. Civil engineers use it for traffic lights, and retailers use queuing theory to reduce wait time. Potential GCSE content In this activity, students will learn how to determine the mean and calculate the median from a frequency table, compare two data sets using an average and measure of spread and find the quartiles and the interquartile range (IQR).

Use proportional reasoning to estimate the radius of a circle of light produced by shining a torch at various distances from the wall This is an engaging activity for GCSE students in which learners will estimate the radius of a circle of light produced by shining a torch at various distances from the wall. In order to estimate the radius, students will need to use proportional reasoning or Pythagoras theorem. Students are encouraged to use GeoGebra to gather data. Problem Solving To solve the problem presented on the first slide, students will have to employ proportional reasoning. This can be utilised to reinforce concepts of enlargement, and potentially Pythagoras if the follow-up question is used. For the second problem, students will need to collect data, consider how to manipulate the control variable (distance) and organise the data to aid in identifying any connections between distance and area. Some students may choose to create a graph and extrapolate to determine the distance, while others may seek out a function. The related GeoGebra file for this activity can be viewed at the GeoGebra website. What is GeoGebra? GeoGebra is a free and open-source dynamic mathematics software that allows users to create and manipulate mathematical figures and interact with them in real-time. It can be used to plot graphs, create 3D models, solve equations, and perform complex mathematical operations. It is widely used in education, particularly in the teaching and learning of STEM subjects. GeoGebra is available for use on desktops, tablets, and mobile devices.

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.

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.

Organise water filtration components to create a safe water supply system Activity info, teachers’ notes and curriculum links This activity challenges students to work in small teams to design a water supply system for a small town of 5,000 inhabitants. They have to work within a budget, including giving themselves a profit margin. The activity offers strong opportunities for cross-curricular work with Enterprise. The ‘Catalogue of Components’ handout includes a list of possible parts from which students can include in their design of their filtration system. Water is crucial to human life, but it can also be a killer. Drinking or cooking water contaminated with micro-organisms or chemicals is a leading cause of disease and death across the world. Poor facilities for the disposal of sewage and other waste water can quickly lead to the spread of dangerous diseases. 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. Download the activity sheets for free! All activity sheets and supporting resources (including film clips!) are free to download, and all the documents are fully editable, so you can tailor them to your students’ and your schools’ needs.

In this fun maths activity, students will look at the way the length of the day changes over the year. They will use a data sheet to plot a graph, then interpret the data to work out the date of the longest and shortest days of the year in the United Kingdom. A free activity sheet can be downloaded.
