This sub-collection of materials from the dy/dan collection contains three resources that bring mathematical storytelling to the classroom in the context of ‘percentages and fractions’. Resources comprise:

• Act One: a video or photograph to provide a ‘hook’ to the problem

• Act Two:...

Carom Maths provides this resource for teachers and students of A Level mathematics.

In this presentation the definition of a perfect number is explained and students are challenged to show that 496 is a perfect...

Fragrances are full of science, and this activity provided by ASE will enable students to create their own stunning scents from scratch. This resource offers a different way of approaching separating mixtures by linking with other sensory and particle model ideas. Effective use of diagrams, clear explanations and...

The Nuffield Foundation provides this resource which reviews the perimeter and area of rectangles and shapes made from rectangles. The activity can be introduced by viewing the slideshow and a student information sheet, which contains the main points is also provided. The activity cards allow students to...

This resource is part of a Nuffield Maths collection exploring Shape and Space. The demand is roughly equivalent to that in Higher Level GCSE and Level 2 Functional Mathematics.

Students explore perimeter and area by asking 'How much lawn feed will be needed?' Students find the perimeter and area of...

This booklet was written to support the Periodicity and Atomic Structure option in the Nuffield Chemistry Sample Scheme Stage III: A Course of Options. The booklet starts with an account of atomic structure which is then related to the periodic table and leads on to a...

In this SATIS Revisited resource, students examine data, perform a risk assessment, and see how risks are sometimes reported in the media.

This unit focuses on the consumer and considers whether or not we should be concerned about any pesticide residues that may be found on fruit and vegetables. In the first...

This Catalyst article explores whether the use of mobile phones increases the risk of cancer, including a recent study from Denmark which investigates the issue further.

This article is from Catalyst: Secondary Science Review 2011, Volume 22, Issue 2.

The Earth's population is increasing, but at the same time the amount of suitable farmland is decreasing due to factors including climate change and the growth of cities. Producing sufficient food to feed everyone is a global challenge. This activity sheet builds on students' knowledge of photosynthesis and plant...

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

• Identify natural ways in which rock can be physically broken up.           
• Identify natural ways in which rock can be eroded.    
• Describe the difference between...

A Catalyst article about the video or computer games industry which is now the biggest entertainment-based industry on the planet. Often it is physicists developing new concepts, hardware and games. To beat the competition they need to make physical aspects of the game be more realistic or at least appear to be...

This video provides a brief introduction to the seven base units used in physics. Base units are identified with their symbols and S.I units.

The origin and definition of the metre is explained and reference to Wikipedia is made for definitions of the other base units....

This resource contains four instant maths ideas, ideal for use as starter activities, extension work or as probing questions to assess understanding. The activities provide students with the opportunity to photograph and consider the plans of unusual objects, create plans and elevation drawings of solids made from...

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

• Recall that plants are living organisms that need food to stay alive and grow.

• Recall that plants are producers that use a process called photosynthesis to make their...
