A function is defined so that f(xy) = f(x) + f(y) for all positive integers x and y. Students are given the value of f(10) and (40) and are challenged to determine the value of f(500).

In each student worksheet contains different values for f(10) and f(40) but for...

The aim of this investigation is to find the value of a number of resistors using a Wheatstone bridge.  Although this is an historical piece of equipment that has been superseded by modern methods it provides an excellent way to understand potential difference in circuits.

This physics extension module from the Salters' Science course focuses on the physics and electronics behind each part of a television set. Production of electron beams and their deflection by electrical or magnetic fields are shown and students see how colours can be...

From Understanding Animal Research, these materials help students understand the process of drug discovery and development. It shows that the drug discovery process is long and complex and involves several different stages, including basic research, animal testing and clinical trials. The materials include: *...

In this activity from stats4schools, students investigate how families spend their money by using a Family Spending report. Students plot appropriate graphs using ICT, interpret data from tables and graphs and understand where the average family spend their money including looking at the cost of living. Students...

In this activity students take on the role of Earth observation scientists submitting a request for an image they would like for their research. This gives them the opportunity to consider the possibilities of pictures taken from orbit (and the limitations) and to write scientifically for a specific audience. It...

In this lesson, students learn about agriculture and the different types of farming systems in the UK, including higher welfare and free-range systems of meat and egg production. They also learn about the principal crops grown in the UK and food assurance schemes to inspect fresh produce and ensure it meets...

In this unit from the Nuffield Primary Solutions in Design and Technology, students design and make a bowl of fruit salad to share with the other children in the class. Students need to consider the look, feel and taste of the fruit salad so that it matches the requirements of the group, as revealed by their own...

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 ‘...
