KS3/4 Science - Demonstrating Biology: 8 Demonstrations

Description

Dr Mark Loughlin, a molecular biologist, looks at some demonstrations which relate to the human body and can provide the wow factor for pupils without the need for expensive equipment.

The first section of the programme which looks at the digestive system starts at the Science Museum with Alexis Gilbert conducting an explosive experiment to show how much energy is stored in icing sugar.

He also uses a range of everyday household products to demonstrate the digestive process, all the way from gums to bums.

The second section concerns the circulatory system. Cathy Deakin at King Charles I School, in Kidderminster, performs a tracheotomy on a pig's entrails to inflate the lungs.

In another less daunting experiment she uses a trolley full of balloons, a leaf blower and a net to simulate what would happen if blood did not clot.

The third section looks at the human brain, with some amazing illusions with experiments on reaction times and eye dominance.
