Resources by Institution of Engineering and Technology (IET)

Pythagoras theorem

This worksheet challenges students to answer a series of questions themed around using Pythagoras theorem. It provides worked examples, examiners top tips and answers to each question. The resource is useful for teaching maths content in design and technology, or as a maths activity sheet.

Queuing systems

This resource from the IET Faraday programme, supported by MEI and Tomorrow's Engineers, provides students the opportunity to explore the mathematics behind queuing at a shop till.

"Queuing theory is the mathematical study of waiting lines, or queues. In queuing theory, a model is...

Rainbow reflections

In this STEM activity, pupils will use a torch and a CD to create rainbow reflection patterns on a piece of paper. Pupils will develop their understanding of how light reflects off objects, the colours that make up white light and how these are separated when shone onto a CD. This activity could be used as a...

Range of Human Hearing

This activity, from the Institution of Engineering and Technology (IET), allows students to investigate the range of human hearing, to explore the pitch and frequency of sounds and to calculate the wavelength of sounds.

Ratio and Proportion

This activity, from the Institution of Engineering and Technology (IET), helps students develop an understanding of ratio and proportion. This knowledge is applied in subsequent activities when preparing the necessary polymers to be used in the manufacturing of their...

Ratios

This worksheet challenges students to answer a series of questions themed around using ratios when creating drawing to scale and calculating gear ratios. It provides worked examples, examiners top tips and answers to each question. The resource is useful for teaching maths content in design and technology, or as a...

Recipe for success

This resource focusses on developing the understanding of ratio, fractions and scaling, by scaling up ingredients in a recipe. It could also be linked to learning in food technology, to demonstrate a practical application of maths. In this activity learners will scale up a cookie recipe that makes six cookies to a...

Recycling

This scheme of work, produced by the Institution of Engineering and Technology (IET), allows students to investigate environmental issues in the context of the design and operation of a new school. Students are introduced to the concept of recycling and then apply their...

Reindeer treat reactions

This experiment from the IET helps children learn about oxidation, chemical reactions, acids and alkalis by testing a range of liquids on fruit slices left out for Rudolph on Christmas Eve. The resources provided include full lesson guidance, as well as a challenging maze puzzle to support assessment and increase...

Remote Medicine

This video, from the Institution of Engineering and Technology (IET), explains how a telemedicine system is used by hospitals in the south-east of England to allow consultants to view injuries to patients and offer advice remotely. Software engineer, Scott Reynolds,...
