The main aim of this resource is for students to understand the impacts of anthropogenic nitrogen pollution on heathland plant communities. The resource provides practical, scientific investigations without the need to organise a field trip.

The resource is divided into three separate activities:
*...

The Nuffield Foundation provides this activity where students suggest types of function to model ozone hole data, before using a graphic calculator or spreadsheet to find at least two particular models. They then consider how well their functions model the data and what they predict for the future. The slideshow...

In this activity from the Nuffield Foundation, which uses a scenario of parking permits at a college to introduce the topic, students learn about collecting data by stratified sampling and designing a questionnaire. A full review of relevant statistical terms is provided, together with instructions of how to select...

This resource, produced by SEPNet and Queen Mary University of London, uses Lego to represent the building blocks of matter. Different colour Lego bricks are assigned to different quarks and leptons. The quarks can be put together to make hadrons, such as protons and neutrons. The blocks can also be used to show...

From the Integrating Mathematical Problem Solving project by Mathematics for Education and Industry (MEI), this activity for post-16 students demonstrates that coffee cools gradually because it is hotter than room temperature and heat is lost to the room. Mixing the coffee with milk also cools it but this effect is...

Many topological graphs have edges that cross. The aim is to re-draw the graph in such a way that none of the edges cross. The task informs students they are required to design a printed circuit board and since the wires are not insulated they must not cross.

Planarity: presentation - an...

This resource contains seven activities related to population statistics.

Data Assessment...

The presentation presents a box containing m white balls and n black balls. Students are asked to explore the probability that if two balls are chosen consecutively, without replacement, the two balls are the same colour. A spreadsheet simulating the situation is provided to enable students to experiment. The...

This resource from Practical Action includes a presentation and worksheets which give Key Stage Three and Four students opportunities to understand more about the impact of existing and new products on people and the environment. The presentation is packed with useful activities to reinforce students' learning. The...

From the Integrating Mathematical Problem Solving project by Mathematics in Education and Industry (MEI), this activity for post-16 students shows that correlation can be used to measure the strength of a linear relationship.

Statistical Inference looks for evidence of what is happening in the population by...

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.

The aim of the route inspection problem is to find a route that is as short as possible yet goes down every road once and returns to the starting point. The task informs students that there has been a heavy snowfall overnight and that the students are required to clear the roads in the town centre as quickly as...

In this activity from the Nuffield Foundation, students carry out an experiment to collect data about a trolley rolling down a slope. They then use this data to simulate the motion of a train by fitting a quadratic curve to their data, using a graphic calculator or spreadsheet. The slideshow provides an...
