A Catalyst article about predators. The article explores some general principles about predator–prey relationships and looks in some detail at the adaptations shown by a predatory insect being used in the control of an insect pest.

In this unit of work students consider the implications of prenatal ultrasound in terms of the risks of screening and the certainty of results. It also asks them to consider the ethical and moral implications of the decisions that may arise due to the results of a prenatal ultrasound and...

The fourth and final Royal Society ‘state of the nation’ report considers the ‘pool’ of the UK’s 16–19 year old students taking mainstream science and mathematics combinations suitable for entry to higher education. It makes three major points about these students.

• The size of this ‘pool’ is critical to...

This Mathematics Matters case study looks at the serious problem of coastal erosion. Much of the UK’s coastline is undergoing erosion, placing homes, businesses and other important coastal sites at risk. Mathematical modelling can enable us to understand both the short and long term processes that lead to erosion,...

This resource, from Politeia, responds to the developments in the educational reform of mathematics, published in 2012. It contains a curriculum, drawn up by Professor David Burghes, Director of the Centre for Innovation in Mathematics Teaching (CIMT) at the University of Plymouth. Particular attention is paid to...

The workbook contains two simulations designed to help students to understand what is meant by a random process and to give some idea of the likelihood of particular events occurring.

This collection of resources is produced by the Core Maths Support Programme to support the implementation of Core Maths. The collection contains a range of activities all designed to enable students to use and apply probability in unfamiliar contexts.

This resource is from a collection of Nuffield Maths resources exploring Hypothesis testing. The demand is roughly equivalent to that in GCE A level. The resources typically include slide shows to introduce the topics, student sheets and teacher notes, as well as other relevant resources.

In this resource,...

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 excel program illustrates the effect of introducing bias when throwing coins.

The first interactive excel sheet simulates the outcome of throwing a coin ten times. The probability of each outcome is plotted and...

Students are presented with a normal six sided dice students and are asked to show that the probability of two events 'the score is odd' and 'the score is prime' are not independent. Students are then given conditions for the probabilities of the scores on a biased dice and are challenged to discover if it is now...

This activity involves the quest to show whether two events are independent. Students are required to use a Venn diagram and to apply logic to find all possible combinations of values within the diagram and thus calculate the probability of event A and event B being independent events. The answer provides a full...

In this activity students explore the probability involved in a particular game involving some special dice. The aim is to explain the reasons behind their findings when playing the game using some straightforward mathematics. Students are required to be familiar with...

In this activity Colin and Phil take it in turns to roll a dice. The winner is the first to throw a six. Students are asked to investigate conditional probability to find the probability of each player winning and hence determine whether the game is fair. The presentation provides a complete solution before...
