In this simple STEM activity for kids learners will investigate how a balloon can be used as a simple speaker. They will blow up the balloon, tap it and listen to how to sounds travel through it. They will then discuss the outcome of their experiment and explain why the balloon speaker works in the way that it does. This activity could be used as a starter activity to introduce the concept of sound and how it travels, or as one of several activities within a wider scheme of learning focusing on sound. Activity: Balloon speakers This is one of a set of free 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 using a balloon as a simple speaker to amplify sound. What happens when you tap the balloon? What can you hear and feel? Why do you think this is happening? This is a quick and easy STEM activity that will take approximately 15 – 20 minutes. The engineering context Engineers must understand how speakers work in order to successfully design products that use them, such as phones, music players and TVs. Sound engineers must understand how sound can be amplified and transmitted from one place to another. For example, at a concert. Understanding how speakers work is a very important part of this. Suggested learning outcomes By the end of this exercise students will know that vibrations from sounds travel through a medium in the ear. They will also be able to use a balloon as a simple speaker and explain how it works. Lastly, they will understand how pushing air closely together affects the volume of sound travelling through it.

Making cut-out 3D shapes and counting the number of edges, vertices and faces In this fun maths activity for Key Stage 2, learners will enhance their knowledge and comprehension of 3D shapes. They will cut out 2D nets for a cube, pyramid, cylinder, and octahedron, then fold them to form their corresponding 3D shapes. Through this process, they will also determine and count the number of edges, vertices, and faces on each shape. This activity can serve as a main lesson to develop an understanding of the characteristics of common 3D shapes. Alternatively, it can be integrated into a broader curriculum that focuses on the properties of 2D shapes, 3D shapes, and everyday objects. The engineering context Engineers must regularly use mathematics knowledge and skills as part of their everyday job. Therefore, they must have a good grasp of basic concepts, such as the properties of 3D shapes. Suggested learning outcomes By the end of this activity, students will be able to make 3D shapes such as cubes, pyramids, cylinders and octahedrons from 2D nets, and they will understand the difference between the edges, vertices and faces of a 3D shape. They will know the number of edges, vertices and faces on a cube, pyramid, cylinder and octahedron. Download for activity sheets and templates for free!
