This podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC) looks at how tracking insects can help scientists forecast summer storms and floods, and the role one of Europe's key satellite missions played in the recent floods in Queensland, Australia.

The huge...

Kamlah Kew focuses on traffic lights - designing the layout, changing timings and checking the signals work properly. Tomorrow’s Engineers spoke to Kamlah and she told us about how she loves combining her creative and practical skills to make a difference to people’s lives every day.

Jennie is an apprentice Traffic Maintenance Engineer at Transport for London watching over London's traffic lights, signposts and junctions to keep everyone safe as they drive to work.

A collection of post 16 resources about transcription, translation and gene expression.  These resources are part of the Post 16 genetics and genomics collection.

This interactive excel program allows students to explore the relationship between the transformation of functions and the associated graphs. Functions explored are straight lines, quadratic and cubic functions as well as sine and cosine curves. Each type of function...

This interactive resource, produced by the University of Leicester, is designed to enable students to explore transformations of functions including translations, stretches, reflection in the axes and rotations.

The first activity uses function notation to explore translations parallel to the x axis and...

This interactive resource, produced by the University of Leicester, is designed to enable students to explore transformations of shapes including translation by a vector, stretches, rotations around a point, reflection in the axes and reflections in the lines y=x and y=-x.

The first activity draws a...

This video reviews how transistors work and introduces Moore’s law, i.e., the number of transistors fitted onto a chip increases exponentially with time. 

This means that the size of the transistor must reduce significantly.  However, as the buffer zone (prevents current flowing) between n-type...

This series of activities from NASA take a mathematical approach to looking at transits, eclipses and occultations. They are intended as supplementary problems for students looking for additional challenges in mathematics and physical science from age 11 to 19 years.

The problems were created to be authentic...

These technical briefs focus on ways to transport goods and people in a relatively low cost way. This is important to people in the...

This booklet contains a range of suggested teaching activities and contexts for teaching about transport in animals at A level. Curriculum links include surface area to volume ratio, circulatory system, heart, blood vessles, cardiac cycle, oxygen dissociation curves, ECG,  and blood flow rates....
