This activity has been created for MYP5 Integrated Science. It covers the Powerstroke, the key force-generating step used by myosin motor proteins.  Topic:Skeletal muscle tissue is made up of muscle cells organized into bundles called Fibres. Each fibre has smaller bundles called Myofibrils, which are composed of myofilaments arranged in sarcomeres. Each sarcomere is a contractile unit composed of thick myosin filaments and thin actin filaments. Myosin filament heads link to the actin fil

Geographic Knowledge and Understanding Measuring trends in resource consumption, including individual, national and global ecological footprints.  Key ConceptsThe scale of ecological footprints vary between individuals within a country, between nations and regions. The process of living creates an ecological footprint. Future possibilities in terms of the increase or decrease of a nation’s ecological footprint  will depend upon the nation's governance. AimsBe able to explain how resource consump
