A resource aimed at advanced level biology students with each step of the electron transport chain (oxidative phosphorylation) clearly and succinctly described in a series of bullet points. The challenge for students is to use this information to draw their own diagrammatic representations of each process. This resource is best used after a taught lesson on the electron transport chain and a means of recapping each point. Students should have experience in drawing out reaction pathways (e.g. in glycolysis or Kreb's cycle) before they attempt this activity. A shorter DRAW IT activity is included for both the Link reaction and Kreb's cycle as a bonus resource. Key words: electron transport chain, final acceptor, chemiosmosis, hydrogen ions, electrons, carriers, ATP, coupled, ATPase, energy, oxidative phosphorylation

A resource aimed at GCSE or Advanced Level Biology students that introduces the concept of pathogens, mechanisms of disease and non-specific defence mechanisms including barriers, inflammation and phagocytosis. The activity is part of the DRAW IT! series of tasks which serve as a great way of getting students to understand a lot of complex information quickly. The class is split into two, with one half receiving written descriptions and being required to draw illustrations for each piece of information; meanwhile the other half of the class receives the illustrations and is required to write written descriptions. After both sides of the class have finished (or after a pre-determined time interval has passed), each student should be paired up with someone who has completed the opposite task to them. They then spend a brief period of time verbally summarising each process to each other. Finally, a class discussion is held between students and teacher, with questioning used to check understanding and a breif summary produced on the main board.

A resource aimed at either high ability GCSE students as a recap of the basic facts of photosynthesis or at advanced level students to recap GCSE information. The worksheet covers the basic facts about photosynthesis and gas exchange in a typical dicotyledenous leaf.

A ten question multiple choice test aimed at advanced level biology students as a way of assessing their knowledge and understanding of photosynthesis.

A worksheet aimed at advanced level biology students as a quick review of the main details of the fluid mosaic structure of cell membranes. There is a clear diagram that requires labelling along with follow-up questions on the function of each component.

A worksheet aimed at advanced biology students that reviews the causes, mechanisms and treatment of cholera. Useful as a starter or plenary activity following a lesson on this topic.

This is a highly engaging activity aimed at 11-16 year olds, but which could easily be adapted for younger children. The activity involves producing a simple microscope from a plastic tumbler, cling film and water. By placing water into a cling film well, students create a lens which refracts light and magnifies objects that can be viewed at the bottom of a plastic tube. Students can alter the shape of the lens and the amount of water to see the impact on magnification. The activity sheets include full instructions (with photographs) on how to set up the microscope and also a table of results for students to fill in details of specimen size, image size and calculate the magnification. For younger students , the second page of the activity sheet provides details of how to set up the microscope; students could then be taken on a nature trail or encouraged to observe small specimens around the room (sweets work well!) Key words: magnification, activity, microscope, specimen, lens, refraction

A worksheet designed to be used at the start of a topic on energy flow with A-Level Biology students. The worksheet provides a series of tasks which require students to conduct their own research and identify the key methods of nutrition, how energy is transferred and why energy is lost at each transfer stage. Extension work is aimed at students researching chemoautotrophs and realising that the sun is not always the start of a food chain. Key words: energy, transfer, parasite, holozoic, saprobiont, autotroph, chemoautotroph, photoautotroph, consumers

Climate change is sometime a 'dry' topic and difficult to include much in the way of practical experiences for students. This worksheet contains a practical procedure that looks at the effect of temperature on the heart rate of Daphnia and the resultant impact on ecosystems. There is also provision for the analysis of results using 95% confidence limits and standard error. An engaging way to look at the impacts of climate change and global warming on living organisms. Key words: Daphnia, heart rate, climate change, global warming, temperature, food chains, ecology, 95% confidence limits and standard error

Key words: Statistics, Daphnia, heart rate, caffeine, 95% confidence limits, standard error, standard deviation, significance, null hypothesis

Aimed at either GCSE or A-Level Biology students, this activity is part of a DRAW IT series of activities. A class is divided into two halves: one half gets the diagram and has to write a commentary as to what each stage in the diagram is depicting; the other half gets a written commentary about the process and has to draw a diagram representing each stage. The two halves of the class can then be paired up to discuss the process of eutrophication, before asking students to summarise during class discussion or on the main whiteboard of the classroom. An easy way to get information on a complex process across to students quickly. Key words: Eutrophication, draw, write, pollution, algae, sunlight, photosynthesis, decomposition, decay, oxygen, respiration, death, fish, organisms, aquatic
