Program a prototype system to alert homeowners flooding risks The flood prevention strategies activity tasks participants to program a prototype system to alert homeowners flooding risks. Flooding is becoming increasingly common in parts of the United Kingdom and causes a lot of damage to peoples’ homes. The sooner a potential flood can be detected, the more time homeowners have to prepare and to save their property. This is one of a series of resources to support the use of the BBC micro:bit in Design and Technology lessons. Damage caused by flooding can have widespread effects on people’s lives, homes, businesses, and agriculture. Authorities aim to provide adequate warnings when the risk of flooding is likely, however this can be challenging. Activity info, teachers’ notes and curriculum links In this activity, learners will debate the social impact of flooding and how design and technology could provide solutions to this. They should think about how programmable systems could be used to help homeowners and the authorities respond better and provide earlier and more effective warnings that flooding is likely to occur. They will then develop a working flood warning system using the BBC micro:bit.

Learning to programme using BASIC language commands This activity is designed to build on understanding of programming commands and what they are used to do in a program. It requires students to show a detailed knowledge of each command and what it is used to do. It also requires them to apply programming commands in a real context. Students will engage with the BASIC language commands, understanding their purpose and how they function. They will write their own program to control an LED light, seeing first hand how their code translates into action. BASIC is a simple programming language that can be used to program electronic systems. It consists of a set of commands that can be used to perform particular functions. 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 engineering and design and technology (DT). Activity: Learning to programme using BASIC language commands This activity involves understanding and applying BASIC programming commands. Starting with a discussion about the language and its common commands, students will then predict the functions of commands like ‘high’, ‘low’, ‘goto’, ‘wait’/‘pause’, ‘if’, ‘else’, and ‘stop’. They will put their understanding into practice by writing a program to control an LED light. Reflection on their experience and a question-answer session will round off the activity, consolidating their learning and addressing any queries. The engineering context Programming plays a crucial role in engineering, especially with the rise of programmable systems, such as smart devices and autonomous vehicles. By learning to program in BASIC and applying it in a real context, students get a sense of how engineers use programming to create solutions and control systems. Suggested learning outcomes Through this beginner activity, students will gain an understanding that programs can be written using programming code. They will learn the purpose and function of a range of BASIC programming commands, and they will also get a chance to write a program using these commands to meet a given design brief.

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.

The History of Christmas tree ornaments The history of Christmas tree ornaments is a fascinating tale that dates back centuries. Historians trace the tradition of decorating trees during the holiday season to ancient civilisations like the Egyptians, Romans, and Vikings, who adorned trees with symbols of prosperity and religious significance. However, the modern concept of hanging ornaments on Christmas trees emerged in Germany during the 16th century. Initially, these ornaments were simple decorations made from fruits, nuts, and candles. Over time, the ornaments evolved, incorporating glass-blown baubles, delicate figurines, and intricate designs. Today, Christmas tree ornaments are cherished keepsakes, reflecting cultural traditions and personal memories and symbolising festive cheer and celebration.

Try out this fun science experiment, designed for primary school students, to catch Santa as he delivers your presents by creating an electronic trap! The engineering context Engineers need to be able to understand how electrical circuits are drawn and communicated; This includes the use of circuit symbols to produce circuit diagrams and schematics. This knowledge could be used when investigating, designing or making electrical and electronic circuits in the future. What equipment will you need? A thin piece of sponge – a washing up sponge is great, but make sure it is completely dry, Scissors, Masking or sticky tape, Aluminium kitchen foil, 3 crocodile leads (you will need another 2 if you do the extension task), A 2 x AA battery pack, A 3V buzzer How to do it Step 1 - Cut a square of the thin sponge approximately 10cm x 10cm. In the centre, cut a hole approximately 4cm in diameter. ⚠ Be careful when using scissors. Always have an adult on standby in case you need help. Step 2 - Cut two pieces of aluminium foil slightly smaller than your piece of sponge. Step 3 - Using masking or sticky tape, tape one piece of aluminium foil to the top of the sponge and the other to the bottom. The tin foil pieces MUST NOT touch if the sponge is not pressed down but should once it is pressed. Step 4 - Attach one crocodile lead to the top piece of foil and one to the bottom piece. You have now built the pressure pad for your Electronic Santa Detector, but you need to put it in a circuit for something to happen. Follow the diagram in the activity sheet below to connect the components with your crocodile leads. When you gently press the centre, the buzzer should sound. Now all you need to do is leave it somewhere you think Santa will stand when he delivers your presents. Just inside your bedroom door, perhaps, or at the end of your bed with your stocking. When he steps on the pressure pad, the buzzer will sound and alert you to him being in the room. You might also want to disguise it so it is not noticeable. Santa is old and wise, and if he sees it, he will know not to step on it! Download the Make a trap to detect Santa activity sheet for free!
