This resource, from the Institution of Engineering and Technology (IET), allows students to investigate the wide range of sophisticated imaging technology available in modern hospitals, and to explore the latest ideas in search-and-rescue robotics.

In this practical activity, from the Institution of Engineering and Technology (IET), students investigate aspects of signal processing. Working in teams, students convert an analogue brain signal into a digital format and transmit it across the classroom to another...

In this activity, from the Institution of Engineering and Technology (IET), students carry out some data analysis to find the best material from which to make a prosthetic foot. They plot graphs of stress against strain and calculate the modulus of elasticity for a...

In this practical activity, from the Institution of Engineering and Technology, students investigate the properties of smart springs and see how they might be used as muscles in a robotic arm. This activity can be used as an extension to the related activity ‘...

Man-made satellites are put in specific orbits around our Earth and other planets to do certain jobs e.g. to send digital communications or to monitor the weather. These orbits can be distinguished by height above the planet and the orbital period. The orbits of natural satellites are much more varied and these...

This resource contains a series of tasks which builds pupils' knowledge and understanding of combustion and how to evaluate what makes a good fuel. In the initial task pupils' are introduced to the properties of complete and incomplete combustion and this is then applied to the combustion reactions that take place...

In this activity students are required to interpret information conveyed in unfamiliar forms: data from maps and tables, to explore the claims that "The frequency and intensity of heavy precipitation events have increased since the 1950s over most land area, and human-induced climate change is likely the main...

This resource, from the Association for Science Education (ASE), is based on a well-known quiz format. It is a PowerPoint presentation, and works well in class or as a lunchtime competition using overheads. The quiz could be run during lunch times as an inter-form competition, or within class time. After teachers...

Produced by ARKive, a database of stunning natural history images, this activity is designed to teach students aged 11 to 14 about the identifiable features of different types of animals and how they are classified. The activity is also suitable for students aged 14 to 16 and beyond. Using a quiz format, students...

This Catalyst article looks at how plant breeders can claim rights over the varieties they develop. It also focuses on the question 'Does this give them too much control?'.

This lesson aims to give a flavour of behavioural ecology in the context of African field work, using role play. Some students play the part of baboons, interacting with each other in the same way as a wild baboon troop. Other students play the biologists, studying the baboons in their natural habitat and trying to...

This 30 minute activity encourages pupils to consider who is responsible for ensuring we achieve the Global Goals (also known as the Sustainable Development Goals, SDGs).
