This A2 level Applied Science resource guides students to research, select and use quantitative chemical analysis techniques to assay the active ingredient of common medicines. There are suggested methods to select from, questions and guided steps for calculations involved. The resource also contains student sheets...

This Catalyst article looks at cuttlefish which have a remarkable ability to change their appearance at high speed. But how do they do this?

This article is from Catalyst: Secondary Science Review 2016, Volume 26, Issue 4.

Published in late 2013, this report contains the findings of a research study which looked into the use of electronic books (e-books or i-books) within continuous professional development (CPD).

The research looked in particular at the way that teachers on the 2013-14 National STEM Learning Centre and...

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

• Describe the effect on a simple circuit of changing the voltage of the battery.
• Describe resistance (in Ohms, Ω) as a measure of how hard it is for charge to flow.
• Explain...

This simulation looks at resistance in a wire. Students can change the resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of a wire as the variables are changed.

Two videos investigating the resistance of a wire. The first video allows students to carry out an experiment on the resistance of a length of wire from home and the second evaluates the results by drawing a graph. This is a required practical students to be able to understand and carry out for GCSE Combined...

Students are asked to design and make an acrylic fridge magnet that would remind a specific type of user to recycle the waste produced within their kitchen at home. To begin students are asked to identify some typical workshop tools, to embed the task within the resistant materials area of design & technology....

This builds on from GCSE work on resistance to investigate the resistivity of a series of metals in the form of wires.  This is common and simple investigation where students can look at developing their measuring skills, especially with calculating the area of the wires.

This engineering resource, produced by Mathematics in Education and Industry (MEI) for the Royal Academy of Engineering, asks the question: how can production outcome data from a manufacturing process be analysed to optimise the process? Students consider the outputs of resistors to see the outcomes form a normal...

Two videos for investigating resistance in series and parallel circuits. The first video demonstrates the experiment to measure voltage and current, and the second calculates the resistance values. This is a required practical for students to be able to understand and carry out for GCSE Combined Science and Physics...

This video explains how horizontal (x) and vertical (y) components of a vector (resultant) can be obtained by constructing a right-angled triangle and using trigonometry.  Two examples are given.

1. A plane flying N-E (60⁰ from north) at 50m/s.

The horizontal component = 50cos30⁰

The vertical...

Subtangent's resources for mathematics include different types of isometric grids which can be printed, a set of lesson starter activities, a variety of worksheets to practice arithmetic skills and graph paper with axes and different quadrants labelled, all of which can be printed freely.

The lesson starters...

STEM Clubs Quality Mark

STEM Clubs are a vital part of school life and regular club meetings bring great benefits to your school. If you have a thriving STEM Club, you may want to showcase the amazing provision that you have put in place for your students. The...

This School Science Review article looks at a selection of resources currently available for use in the teaching of astronomy in UK schools. It is by no means an exhaustive list but it highlights a variety of free resources that can be used in the classroom to help engage students of all ages with astronomy and...

This collection of resources from the Royal Meteorological Society and Royal Geographical Society with IBG uses statements and figures from the Intergovernmental Panel on Climate Change (IPCC)...
