Populations

These resources from the Wellcome Trust look at how populations grow, change and move, and why understanding them is so important. The resources use real research to illustrate many aspects of the study of populations, including:

*ecology *epidemiology *demographics *population genetics *evolution and the...

The fundamentals of programming are covered:
• Arithmetic operations
• Data types
• Control flow

As well as some more advanced techniciques including the use of:...

Building Images

In this activity, students create colour images from satellite data. This allows them to study how different surfaces reflect different wavelengths of light, how coloured images are created using an RGB model, and how band combinations can be chosen to examine a particular landscape effectively.

Seeing Temperatures

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...

Online ecology two - the distribution of species across a field

This online ecology practical, by SAPS, is designed to give students an opportunity to see how systematic sampling can be used to

  • investigate changes in species richness across a footpath
  • the distribution of species across a footpath

These online exercises are not intended as a...

Double helix images

A series of images representing double helix images.

  • DNA double helix and sequencing output: molecular model of a DNA double helix showing the individual atoms (apart from hydrogen) as coloured balls. Carbon atoms are in white, oxygen in red, phosporus in purple and nitrogen in blue....

Semi-conservative replication images

A collection of images representing semi conservative DNA replication:

Illustration depicting semi-conservative DNA replication 1. Three generations of DNA are shown. After separation of the DNA double helix, two new complementary DNA strands are synthesised (indicated by a new colour)....
