This is the first lesson of 12 for OCR 21C unit B4 Homeostasis. The lesson covers an introduction to homeostasis, effectors, receptors etc. In the notes section below the slides i have written my lesson notes. Have also attached the worksheet. Hope this proves of use.

Students use sheet to track their progress through the unit against 'I can' statements (foundation + higher). End of each lesson students can tick off statements covered and record their understanding (i get them to draw smiley or sad faces next to the statements). Students can use the record to target revision on areas of least understanding, track revision and show progress by indicating where understanding has improved i.e. a sad face has become a smiley face. Students can also set targets against the statements and indicate areas where they are in need of support.

This is a workbook i have put together for my students. It coveres the first part of OCR F212; magnification, cytoskeleton, eukarotic + prokarote cell structure. It contains a specification overview and a range of questions / activities that can be used in class / for revision / homework. A number of the activities have been adapted from other worksheets, however, i do not know the original sources. If you are the original source and would like to be acknowledged drop me a mail.
