A selection of short, engaging practical demonstrations on various biology, chemistry and physics topics. The page also leads to many other useful resources. You will need to join TES in order to download the demonstrations but it is free and only takes 30 seconds!

A powerpoint activity covering different specialised cells. Includes: sperm and egg cells, nerve cells, palisade cells (plant), ciliated cells, root hair cells and red blood cells.

Some lovely images and animations. The commentary may be a bit advanced for 11 year olds and pupils could get lost in this fascinating site.

An excellent flash animation that helps pupils to understand how small cells are. Different cells (and a dust mite) are placed on a pin head and you can zoom in to seem them.

Bitesize revision on cells and systems leading to an activity and a test.
