The reduction mill reduces the thickness of a strip of steel using a series of rollers, each roller making the steel slightly thinner. The percentage reduction is constant on each pair of rollers. The mathematics used to calculate the actual reduction is similar to that used when calculating compound interest....

This SMILE resource contains two packs of games, investigations, worksheets and practical activities supporting the teaching and learning of reflection, from investigating folding symmetry to using matrices to perform reflections.

This resources uses 5 key questions to develop a rationale for assessment within D&T. Through answering each question, the responses are intended to support, challenge or structure department discussions on your own assessment in D&T in your school.

• What does it mean to be a successful student...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Recall that light can change direction (refract) when it passes across a boundary between transparent media
• Describe how the angle light passes across a boundary between two...

Practical Action have supplied this teacher's pack to challenge students to use their STEM skills to come up with solutions to a problem of water shortage in Sudan. The pack includes a PowerPoint presentation and Teacher Guide so that teachers can outline the problem to their students. The PowerPoint makes...

This resource provides a lesson plan showing how to use system thinking to teach about ecosystems. The approach used in the lesson is based on education research which is summarised in a separate research summary document.

The lesson includes an activity where individual pupils are given an organism. They...

This resource from CensusAtSchool uses the ideas of estimating probabilities through finding the relative frequency of given data about favourite subjects at school. It uses sampling from different populations and investigates the effect of sample size on the estimated probability.

This collection from The Royal Statistical Society Centre for Statistical Education (RSSCSE) has been written to help make statistics lessons more relevant and engaging to teachers and students.

Having run the well known CensusAtSchool Project for the last eight years the RSSCSE are well aware of the impact...

Telemedicine is a new and fast developing field in healthcare. Even 20 years ago the idea of a surgeon being able to operate a robot from hundreds of miles away in order to perform an operation seemed like science fiction. Today, this is not only possible but engineers, working with scientists and doctors, are now...

This activity sheet is based on the Inventive Podcast.  It introduces electrical engineer Jack Howarth, and links his work to a physics topic. The activity sheet also supports Careers Benchmark 4: Careers in the curriculum by introducing a career and role model. There are also links to short audio clips of Jack...

The aim of this resource is to give students the opportunity to investigate the use of science, technology, engineering and mathematics when controlling Remotely Piloted Air Systems (RPAS). Students will use computing and maths skills to create a flight plan for RPAS.
