Scaling activity to change the size of items By applying mathematical knowledge and solving problems involving scale factors, we can manipulate scaled-up or scaled-down drawings. In this fun STEM activity for KS2, students will learn how to change the scale of items, by doubling or halving the size and drawing them to a new scale. This is an engaging and practical exercise through which students will gain a deeper understanding of multiplication and division and how they are useful methods to change the scale of items. This is one of a set of resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within maths and science. This resource focuses on the use of multiplication and division in the context of scaling an item to either double or half its size. This versatile activity could be used as a main lesson activity to teach learners how to work out scale or to reinforce understanding of multiplication and division. It could also be used as one of several activities within a wider scheme of learning focusing on the use of maths to understand ratio and proportion. Additionally, it could support the development of drawing skills in art. This is a Halloween-themed exercise that could be done as individuals or in pairs. Students will first use a grid to scale up a drawing of a pumpkin into a larger grid. Once this is completed, students will scale down a drawing of a ghost into a smaller grid. By utilising multiplication and division, students will gain valuable skills in the scaling of items. This activity will take approximately 40-60 minutes to complete. Tools/resources required Halloween Multiplication and Division Activity… Worksheets Pencils Erasers The engineering context Structural engineers work with architects to help design most houses, hospitals, office blocks, bridges, oil rigs, ships and aircraft.

Learn about liquid and gas in this fun science experiment to make a snow blizzard In this simple and festive activity for kids, students will create a snow blizzard in a jar! This activity can function as a fun science experiment for the young engineer at home or as a full lesson in school to think about gas and reactions. What equipment will you need? A jar, A pot for mixing paint, Water, Baby oil (enough to fill ¾ of your jar), A small amount of glitter, Bicarbonate of soda or an effervescent tablet, A small tube of white paint, Blue food colouring, A stick for stirring How to do it Step 1 – First, fill the jar until about ¾ full of baby oil. Step 2 – Mix water and a few tablespoons of white paint in the pot. Step 3 – Return to the jar of baby oil and add the glitter and blue food colouring. You can add as much of these as you like – you are creating a magical winter scene! Step 4 – Add the paint and water mixture into the jar, filling it to the top. Step 5 – Lastly, add a teaspoon of bicarbonate of soda. Adding the bicarbonate of soda will start the blizzard! The science behind the experiment Oil is less dense than water, less heavy; This means the water sinks to the bottom of the jar, and the oil floats on top, and as they don’t mix, there’s a separation between the two. When you add the bicarbonate of soda or an effervescent tablet, it reacts with the water to produce carbon dioxide gas bubbles. These stick to the water droplets. The water and gas combination is less dense than oil, making them rise to the top of the jar and create pressure in an upward direction. At the top, the gas bubbles pop and escape into the air, leaving the dense water behind to sink back to the bottom again. This reaction creates our beautiful blizzard in a jar! The engineering context Understanding the way different materials work and the properties they all hold is vital in creating and developing solutions to our world’s problems. Engineers are interested in the world around them, which is a fun and critical spark to ignite from an early age. Download the Snow blizzard in a jar activity sheets for free!

Learn about sound waves in this free STEM with this free lesson plan for KS3 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 that 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. Tools/resources required Calculators 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.

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’. The engineering context Living in a highly technological world, where access to information and entertainment is at our fingertips, the Inform and Entertain Me topic is a gateway to engage and introduce students to the principles and technology that form the basis for communication devices that are used in our everyday lives.

How to draw an exploded view This is one of a set of resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within design and technology and maths. This resource focusses on drawing exploded views of products. Different types of drawing are used to communicate different types of information. Exploded views show how the component parts of a product relate to each other. These are widely used to support the assembly of products, for maintenance activities and when building flat pack furniture at home. Producing an exploded view develops drawing skills, whilst simultaneously allowing concepts such as dimensions, proportion and scale to be introduced in a practical context. In this activity learners will produce an exploded view drawing of a pen, working in proportion and ideally to scale. This could be used as a one-off activity, an extension to maths learning on scale, or linked to D&T activities such as product analysis or section drawing. It could also be used in conjunction with the IET primary poster – Exploded Views. Download the activity sheets for free!
