This resource contains a short presentation which introduces three problems where approximate solutions can be calculated.

The first activity asks students to use Fermi estimation to calculate the quantity of tea used in China in a three month period. Students are also invited to calculate an estimate of the...

This question asks us to consider a person opening a burger bar, doing all of the cooking themselves, and then estimate how much space should they rent?

The main topics required are rates (number of burgers per hour that one person could cook, number of customers per hour), and areas. 

This Cre8ate maths activity allows the opportunity to discuss the modelling function of mathematics. The tasks allow students to develop their own strategies and to consider the idea of an ‘efficient’ algorithm. In addition, 'First fit and full bins' activity involves work on ratio and pie charts.

Act 1

A simulation is shown of a Ferris-wheel, where one of...

A Catalyst article about what happens as plants grow. During their growth, plants remove compounds of nitrogen, phosphorus and potassium from soil which need to be replaced to maintain the soil’s fertility. For centuries farmers have used organic manures, crop rotation or ploughed in specially grown crops; today...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). New applications for traditional fabrics are being found, but increasingly, fibres and fabrics are engineered for specific purposes. Much...

This video introduces permanent magnets, their fields and how to investigate them using iron filings. It also demonstrates the field between attracting and repelling magnets. 

This guide, from triple science support, offers background information and practical suggestions to support practice when teaching about fieldwork and gives suggestions for securing progression and follow up activities. The guide provides advice on how fieldwork can support the following areas of the curriculum:...

This article from Catalyst focuses on dengue fever. Dengue fever is a mosquito-borne disease found in tropical areas and its range is spreading. The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 2.

Catalyst is a...

This Salters’ Chemistry Course unit from the University of York Science Education Group covered:
* The use and importance of germicides.
* The chemist's role in public health.
* Some of the chemical reactions inside our bodies.
* The function and...

This Catalyst article looks at how exercise affects our immunity and susceptibility to infection. Recent research indicates that a person's level of physical activity affects their immune function, influencing their risk of respiratory tract infections such as a cold. Whereas moderate levels of regular exercise...
