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.

How performance is ranked in sport is the focus of this resource from the Centre for Innovation in Mathematics Teaching. Ranking plays a vital role in many sports, providing evidence for sponsors that a particular player, or team, is worth investment. Specific examples from cricket are provided and students learn...

High levels of ultraviolet radiation out in space drive reactions that can turn white beads into their coloured form. Students investigate how temperature affects the rate at which the beads turn back to white. At key stage five, students can use the results sheet template to find the activation enthalpy. In the...

This MEP resource from CIMT is taken from text book 8A which covers the mathematics scheme of work for the first half of year 8.

Ratio and proportion covers: equivalent ratios, direct proportion, proportional division; splitting an amount into a given ratio, linear conversion; masses, length, currency and...

In this resource students are given the coordinates for each vertex of a triangle, with two of the vertices being horizontal. The challenge is to determine the ratio of the tangents of two of the angles.

Each student worksheet has a different triangle, but the solutions all have something in common.

...

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...

This Practical Action resource enables students to consider the need to reduce the negative impacts of  products on the environment and people. It enables students to evaluate products throughout their lifecycle and learn about inspirational products, companies and access to sustainable design briefs. The...

From Nelson Thornes, these resources help students to reinforce understanding about reaction rates, orders of reactions and the rate-determining step of a reaction. The activity challenges students to determine the order of a reaction from experimental data and deduce the reaction mechanism from this data. These...
