This Primary IET Faraday® DIY Challenge Challenge Day encourages students to consider how engineers work together to solve real-life problems. It enables students to experience the knowledge, understandings and skills engineers use within their work and the ways in which their strengths can be used to achieve an effective outcome. The students will need to work as a team to design a way of getting lighthouse keepers back to the mainland from a lighthouse based on a small island 200 metres from the nearest land. The design will need to use a zip line to carry the keeper safely across the waves which can be high during storms. The students will have access to the Faraday shop and a budget of Faraday money. They will need to plan what resources to buy and manage and record their budget. At times they may need to make decisions about affordability and effective use and should be encouraged to identify alternative, possibly cheaper, approaches to their final designs. At the end of the challenge day students will be asked to present their prototypes by demonstrating how their design could carry the lighthouse keeper safely to the mainland. Designed for six teams of six students (36 students in total) aged 8-11 years, the challenge encourages the development of students’ problem solving, team working and communication skills. This activity day can be tailored to the needs of your school and your students by adapting the PowerPoint presentation and the editable student booklet. The complete set of free downloadable materials includes: Teachers’ pack A list of the practical materials needed, presenters’ notes highlighting key areas and reinforcing key themes throughout the day, some handy hints on how to deliver the day . . . plus printable Faradays currency and student certificates. Student booklet Available as an editable MSWord document to allow the booklet to be adapted to meets the needs of your students and your school. PowerPoint presentation A step-by-step guide for your students throughout the day, with supporting notes for the delivery of the presentation.

Make a non-alcoholic family friendly eggnog this Christmas, and learn about science and mixtures in this quick and easy festive recipe. Learn some amazing scientific facts while making this delicious, creamy Christmas treat - the magic of science is real-life fun! More recently, non-acholic eggnog has become a staple of Christmas celebrations, with Americans drinking over 58 million kilograms each year and Christmas Eve now being named National Eggnog Day. Ingredients needed: 500ml whole milk (swap for unsweetened almond milk if dairy-free or vegan) 200g caster sugar 100ml double cream (swap for full-fat coconut milk if dairy-free or vegan) 100ml water 4 egg yolks (swap for vegan vanilla pudding mix if vegan) 1 teaspoon vanilla paste (remove this ingredient if you are following the vegan recipe) Ice The engineering context Baking is engineering. It is using science, maths and technology skills to engineer and create solutions and new tasty products. Engineers need all these skills – precision in weighing out ingredients, the safety required in the kitchen and product design and quality engineering to test, taste and improve with each delicious creation! Download the free recipe and template! All activity sheets and supporting resources are free to download, and all the documents are fully editable, so you can tailor them to your students’ and your schools’ needs. 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. Oh ho ho, and please do share your experiment highlights with us @IETeducation #SantaLovesSTEM

In this activity students will calculate the area of a circle to design a fault detector system. They’ll use a GeoGebra file to measure the size of the defect in hot steel bars produced by the company. They’ll then have to organise the information they receive into an understandable table. This is one of a set of resources developed to aid the teaching of the secondary national curriculum, particularly KS3, supporting the teaching in mathematics. Activity: Organising mathematical information to choose the optimum size for a ‘fault detector’ coil In this lesson students will engage in a roleplay activity that uses mathematical calculations to figure out the ideal size for a fault detection coil. A company has invented a system to find defects in hot steel bars. The hot cylindrical bar must pass through a defect detector which is shaped like a ring. To work properly the bar must fill between 60 to 80% of the area inside the detector ring. The activity starts with a warm-up question related to circles and percentages to introduce the concept of fault detectors used in factories, where students can check their answers with the fault detectors GeoGebra file. Then, students will need to use reasoning to work out a more challenging problem related to fault detector design. Students will use the same GeoGebra file but they’ll need to work out how to organise the given information to answer the question. Download our activity overview and presentation for a detailed lesson plan and worksheet with answers on making fault detectors using the area of a circle. The engineering context Engineers rely on fault detectors as an essential tool in various manufacturing processes to guarantee the quality of their products. To ensure the safety and dependability of products, engineers must carefully design fault detectors capable of precisely identifying any imperfections or defects. Suggested learning outcomes Working with both diameter and radius, students will be able to use a formula to calculate the area of a circle. They’ll also be able to organise data using tables.
