A highly technical overview of how sound is represented in a computer, how digitising sound changes the quality of it and how reducing the sample rates can effect the resulting audio. The resource also comes with a number of sound samples to illustrate these concepts, along with both Python and Scratch programs to...

This collection of activities gives pupils the opportunity to use a BBC micro:bit to programme their own compass. This activity also provides a link with the art activity in the same collection, giving pupils the chance to code their own tessellating pattern using Scratch. This activity is part of a series of...

Glaciers exposed to particulate matter (pollutants) undergo changes to their surface reflectivity. This phenomena called albedo leads to an increased heat absorption at the surface of the ice and as a result an acceleration in the melting process. This resource includes a practical activity that models the effects...

In this activity students roll rice filled balls (to mimic boccia balls) down a slope and measure the distance that they roll after the end of the slope. The ball is released from different heights up the slope and a graph of stopping distance is plotted. Students must then compete to roll their balls to a target...

A Barefoot Computing introductory programming activity for lower-primary children learning computing. Using the iPad app Scratch Jr, children are given the opportunity to develop skills by tinkering with existing programs as well as creating their own. Children might be offered the chance to tinker with other basic...

In this activity children will discuss the dangers of online situations and think of ways to avoid these. 

There are a set of e-safety scenario cards in the downloadable files. This is a chance for anyone in your household to be joining in and discussing the impact. Remember your SMART rules when staying...

The Nuffield Foundation provide this resource which can be used to introduce the shape and main features of proportional, linear, inverse proportional, and quadratic graphs. Different versions of Excel spreadsheets allow students to explore how the shape and the position of a graph changes when the constants in its...

This resource provides a lesson in which children understand and use negative numbers in the context of
temperatures. Looking at the temperatures of different cities, they find missing temperatures and temperature differences. Temperature scales are provided which could help children who need a visual...

In this experiment, from Science & Plants for Schools (SAPS), students are required to make observations about wild oat seeds. Using a petri dish, glass jar, filter paper and water, students can recreate the conditions of a greenhouse. They can then observe the changes to direction of the awn (the long hair at...

This resource offers a real life context for the Year 6 maths curriculum by giving pupils the chance to calculate profit and solve multi step problems. Throughout this session pupils will revise and apply formal calculation methods when deciding on a selling price for their dishes and they will also need to...

This resource offers a real life context for Year 6 pupils to solve problems involving area and perimeter while designing a restaurant floor plan. Pupils will apply their maths learning to design their restaurant seating area. The session builds in the chance to use online shopping websites to calculate the cost of...

This activity pack provides a range of activities that promote cross-curricular learning, so that STEM can be linked to other curriculum subjects...
