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.

This article is from Catalyst: GCSE Science Review 2005, Volume 16, Issue 1...

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...

For the g-forces activity pupils will be able to discuss how astronauts use forces to simulate the effect of launch and landing on their bodies, when preparing to go into space. The pupils look at the forces on a ball at the end of a piece of elastic and discuss the forces on an Astronaut in a centrifuge. For the...

In October 2007 the Department of Education and the Department for Employment and Learning launched the draft document Preparing for Success for consultation. The aim was to make policy proposals for the future development of Careers Education,Information,Advice and Guidance and to set out a strategy that...

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...

Published in 2015, a working paper from the Curry School of Education at the University of Virginia investigated the persistence of effects of early childhood interventions and asked whether these effects fade systematically. The study found that “by the end of kindergarten [Year 1] children who attended preschool...

This resource contains four instant maths ideas exploring how to represent data graphically. In the first task students record how long they watch TV, group the results and draw two separate graphs to compare boys and girls. The second task requires students to consider what type of diagram is suitable to represent...

In this activity, students use the data gathered during the Wii Fitness investigation to contextualise cumulative frequency curves. Curriculum links include grouped data, cumulative frequency graphs. box plots, median, quartiles and distribution.

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,...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Identify factors that can increase the pressure of a fluid.
• Explain why the pressure of a fluid is a scalar quantity that is equal in all directions.         
• Explain the...

This activity sheet takes students through concepts and calculations linked to pressure in a fluid. It could be used as revision at the end of the topic. The worksheet also  introduces a company called Tyne Subsea who use hyperbaric chambers to pressure-test products which will be used underwater.
