This is a power point explaining all of the key terms related to ecosystems with exam terminology and great pictures and diagrams. I uploaded this onto my school system as a homework to test students on all of the key terms and what they mean. I have also used a plenary to lessons and as revision at the end of the unit.

The work sheet has every key word written and students just fill in the definitions. They can then stick the sheet in the front of their books. The second worksheet is for a class activity, or a home work and sets students tasks to complete on ecosystems, predator - prey relationships, etc. The following terms are stated: classification (artificial and natural), evolutionary trees, binomial system (genus & species), habitat, ecosystem, producer, consumer, pyramid of numbers, biomass , predator, prey, equation foe energy transfer in food chains, energy loss through food chains, parasites, mutualism, interspecific and intraspecific relationships, adaptations (specialists, generalists, extremophiles, anatomical and behavioural adaptations).

This is a 9 slide power point on Respiration. I use this with my Foundation & GCSE Double award class as a class presentation and as a starter for my Triple Group. With Triple groups you will only need to include the chemical equation for respiration and go into more detail with respect to ATP, which is not required for double award. It includes aerobic and anaerobic respiration, differences between the two, the word equations, release of energy (ATP), oxygen debt and RQ quotient.

This is a 16 slide power point following the specification for AS AQA Biology , but would also suit OCR specification. It includes eukaryote and prokaryote cells, differences between them, binary fission, uses of microscopes (both light and electron), changing units, magnification and resolution and finishes with cell fractionation. The last slide leads into the next stage of the syllabus which is different organelles. I have produced a different power point for that to include movement across the membranes as well. Please view if you like this one. Thank you for taking the time to look at my resource and I hope you find it beneficial.
