This resource supports the teaching of instrumental analysis, including gas chromatography - mass spectrometry  (GS-MS) time of flight mass spectrometry, using the context of archaeology. This is done by relating the use of solvents, chromatography and mass spectrometry techniques to discoveries from the study of...

Ian explains that a key part of being successful is having good...

The mathematical solution explains how to find the value of the first and second derivatives of a given function at specific values for x. The function is presented in the form of algebraic fractions which needs to be converted to index notation and the chain rule used to find the differentials.

The mathematical solution explains how to solve the equation: sin(x+150) = 1/sqrt2 for x between 0⁰ and 360⁰. To begin with, the principle values for (x+150) are found. The fact that a sine curve is periodic is used to find the solution set for (x+150) based upon these two initial values. Subtracting 150 from each...

The mathematical solution explains how to find the minimum value and sketch the curve of y = 4x² + 12x + 10. The first method uses calculus, differentiating the function and equating the differential to zero. The resulting equation is solved to find the x value of the minimum point. This value is then...

This resource presents some real seismic data recorded before a volcanic eruption and allows students to locate some of the resulting earthquakes by use of graphs and maps.

Rory Hadden investigates how fires ignite, spread and how they can be extinguished. This research is then used to save lives by creating safer buildings for us to live and work in.

This video demonstrates how adiabatic compression of air can produce enough heat to ignite cotton wool.  The auto-ignition temperature of cotton wool is approximately 400⁰C.  The video could be used to explain the way diesel engines work.

In this video, Matt describes how he became a fisheries technical officer for the Environment Agency. His job is to monitor river habitats and fish populations, including improving the habitat and restocking fish after any pollution incidents.

The video could be used to introduce units of work including...
