Learn how to make papier mâché Easter eggs with balloons in this fun STEM activity for kids In this fun Easter STEM activity for kids, students will learn how to use papier mâché and a balloon to make and decorate an Easter egg that they can use as part of their celebrations. This activity is aimed at primary school students and could be used as a main lesson activity to teach learners about making techniques, design creativity and the use of colour, or part of a wider scheme of learning covering graphics-based techniques. There are also potential curriculum links with the Art department and STEAM based activities. This is one of a set of resources designed to allow learners to use Easter themes to develop their knowledge and skills in Design and Technology and Mathematics. This resource focuses on making and decorating a papier mâché Easter egg with different coloured paints. Follow this step-by-step guide to make your very own papier mâché Easter egg. Download our free activity sheet for more detailed instructions, teachers notes and optional extension work. Also included is a fun bonus maze activity. Tools/resources required A balloon Newspaper and white paper Wallpaper paste (flour and water or PVA glue can be used instead) A small plastic pot Scissors Different coloured paints and other materials for decorating, such as foam letters and card borders Suggested learning outcomes By the end of this Easter STEM challenge learners will be able to use papier mâché and a balloon to make an Easter egg model. They will also be able to use colour to decorate a papier mâché based egg and they will be able to show creativity when designing and making products. The engineering context Engineers make product models to test ideas and see how they will work. Papier mâché can be used to make 3D models. Its other applications include masks for the theatre, structures for carnival floats and even disposable fuel tanks for aircrafts! 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.

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.

Making a moisture sensor to check that a sports pitch is fit to play on In this engineering activity, designed for secondary school students, students will make and test a moisture sensor that referees can use to check the playability of a football pitch. This is one of a series of resources designed to allow learners to use the theme of the sport to develop their knowledge and skills in design and technology and engineering. This free resource focuses on making and testing a moisture sensor that referees can use to check the playability of the pitch. Activity introduction Your task is to make a waterlogging sensor that a referee can use to check whether the playing field is fit to play on. It should indicate when the pitch is too wet for play to safely take place. Follow the steps outlined in our free activity sheet to assemble your own moisture sensor circuit. Once the sensor is assembled place the moisture sensor in wet soil or grass to see if it works! After you have tested your moisture sensor circuit you can discuss with your teacher how successful the making of it has been. This activity will take approximately 50-80 minutes. What you will need A soldering iron, stand, sponge and mat/base Solder Moisture sensor circuit board A 9-volt battery and battery snap A 470-ohm, 1 kiloohm and 1.2 kiloohm resistor A transistor A 5 mm red LED A sticky pad The engineering context Sporting events require engineers of a wide range of disciplines to make sure that it runs smoothly and effectively. From structural engineers in charge of stadium design to textile engineers producing the players’ kits, the importance of engineers is huge. Electrical and electronic engineers need to have basic skills in circuit construction, including soldering components and testing electronic PCBs. Suggested learning outcomes By the end of this activity students will be able to make a moisture sensor circuit, they will be able to fit and solder components to a PCB and they will be able to test the moisture sensor circuit to check how well it works.
