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.
