What causes the different seasons (animation) Animation showing how seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis.
Would You Weigh Less in an Elevator?
What happens when you jump in a moving elevator? Do you weigh more when you're going up and less when you're going down? Carol
Hedden explores the relationship between gravity, weight, and relative
motion, using a moving elevator to explain the fascinating physics. (03:35)

Environment: Following the flows
What affects the atmospheric and ocean flows? This unit explores the mechanisms that are important; the most rapid carrier is the wind. The basic principle of global atmospheric circulation is simple: warm air rises and cold air sinks. How does this principle affect the atmosphere and flow of water in practical terms? First publis
Modelling pollution in the Great Lakes: a review
This is the fifth and final unit in the MSXR209 series on mathematical modelling. In this unit we revisit the model developed in the first unit of this series on pollution in the Great Lakes of North America. Here we evaluate and revise the original model by comparing its predictions against data from the lakes before finally reflecting on the techniques used. This unit assumes you have studied Modelling pollution in the Great Lakes (MSXR209_1), Analysing skid marks (MSXR209_2), Developing model
Introduction to histology
This unit provides an introduction to histology, the study of tissues. It also describes how histology can aid in the diagnosis of disease and explains how histology services are organised within a hospital. First published on Tue, 26 Jun 2012 as Author(s):
Introduction to microscopy
The unit provides an introduction to microscopy and the operation of a simple light microscope, of the type found in histology units and teaching laboratories. It outlines different methods used for preparing and staining tissue sections for microscopy, and explains how different stains can be used to identify particular cells, pathogens and anatomical structures.Author(s):
2.7 Inferring relationships of common ancestry This clip addresses the question of how one might go about building a tree, or inferring relationships of common ancestry, by recognising evolutionary novelties, or share 4.2 Intermediate forms In essence, the argument about intermediate forms runs as follows. If whales evolved from a terrestrial ancestor through the accumulation of small differences over time, we should expect to find the fossils of a number of ‘missing links’, i.e. creatures with a mixture of terrestrial and aquatic characteristics. In fact, we might expect to find a succession of such animals, each a little bit more whale-like and a little bit less well adapted to life on land than its predecessor. To m
