Library lesson

THis morning you will be either finishing off posters or finding and interpreting S.E.M. images to meet the criteria for P4.  Use these sites to start with - http://www.sciencephoto.com/ , http://www.anatomybox.com/tag/sem/ or try searching with google images.  Remember, you need to describe images of tissues and cells, NOT whole organisms like ants.

You can work in a word document, but make sure you explain what each image is in your own words - without using copy and paste.  We'll have a lesson on the microscopes next week, so make sure that you have as much of the other criteria done by today as possible.

These are rod and cone cells from the retina in the eye - they receive light and send nerve impulses to the brain allowing us to see.
