This is a 2 part lesson for muscle contraction. It introduces actin-myosin interactions in the sliding filament theory. I have included some PPT slides from boardworks which highlight this interaction very well. I have also included 2 videos from youtube which I find very helpful. The crash course video can be used in either lesson 1 or 2. The Biology ATP Myosin video is a resource I use along slide the boardworks presentation on muscle contraction where students use both resources and their books to produce a flow chart or bullet points explain what occurs in the sarcomere. There is also an exam question at the end of lesson 2. *please note that you will need to enable macros on PPT to allow boardworks to be interactive

A Word document which can be modified. It contains all of the specification points for unit 1. I have included an exam progression tracker for the 12 exams available and have included the grade boundaries and UMS scores for each exam. These are the modular exams for unit 1 IAL but are also great exam practice for Biology A students in preparation for the May exam. I have included page references for each specification point (from the IAL Book 1 and will need to be modified for Biology A). There is also a RAG section to support student learning.

A collection of 4 lessons that introduce the main themes we will study throughout the course. The first lesson focuses on new vocabulary and approaches in psychology (social, cognitive, learning, biological or psychodynamic approaches). The second lesson introduces the conventions of report writing. Students look at some psychology research papers to observe the correct format. The third lesson focuses on issues and debates in psychology (ethical, gender, cultural, reductionism, nature/nurture) The fourth lesson looks at credibility, validity, reliability, generalisability, objectivity/subjectivity of theory and research.
