Microscopes and Cells
SCN 3-13a - Using a microscope, I have developed my understanding of the structure and variety of cells and their functions
Microscope Function
PowerPoint serves as a guide to an introductory lesson on the use of a microscope.
I find it's best to use pre-prepared slides for the intial lesson. Several schools I have been in have the letter "e" slides... I've found these very useful for initial focussing as the learners know what they are looking for. Furthermore they realise very quickly the image is upside down and moves in opposite directions. I have found learners are very excited to achieve their microscope licence (you can make a big deal about them losing it if they don't treat the microscope with respect...). Also serves as a means of assessment. Useful LinksVideo: Variety of Microscopes

Cell Structure and Function
3D Cells can either be used as an introductory lesson to the structure and function of cells (worksheet a) or as a means of assessment (worksheet b).
You will need to gather materials for the production of cell models or set it as a homework task. I have provided a large PowerPoint file which could serve as a guide through the whole topic of cell structure and function. Pick and choose what you feel is most appropriate for your class.

A matching exercise... useful for helping learners realise the connection between specialised cell shape, structure and function.
