Science presenter Jon Chase describes three different types of microscope. He explains how a light microscope works, and takes a look at sperm, red and white blood cells, and the surface of a leaf. He then discusses the difference between a transmission and scanning electron microscope and views some images of cells, organelles and virus particles under higher magnification.

This clip is from the BBC series Bitesize Science. Scientist and rapper Jon Chase reveals his top 20 demonstrations and brings school science to life using music, magic tricks and everyday objects such as jelly babies, coins, and cups of very sweet tea.

Teaching Biology?

The class could use microscopes in a follow up activity to observe and draw the structure of magnified objects. Interesting objects for students to look at could include different fabrics and the torn edge of paper. Pupils could also look at blood cells (providing an appropriate risk assessment has been completed).

This clip will be relevant for teaching Science - Chemistry, Biology and Physics. This topic appears in OCR, Edexcel, AQA, WJEC KS3,KS4 and GCSE in England and Wales, CCEA GCSE in Northern Ireland and SQA National 4 and 5 in Scotland.
