A resource aimed at advanced biology students, this worksheet is ideal as a starter or plenary recap of the light dependent reactions of photosynthesis. The worksheet includes a space for students to draw out the series of light dependent reactions from memory, but importantly, they are then asked a series of questions to identify the role of each substance. This is a very useful way of ensuring that students have understood the details of the reaction rather than just repeating diagrams parrot-fashion. Key words: photosynthesis, light dependent, photosystems, chlorophyll, chloroplasts, thylakoid, stroma, electrons, reduction, oxidation, phosphorylation, ATP, NADP

The experiment is simple to set up (I recommend using spinach leaves) and straightforward to perform making it an ideal practical to add to what can otherwise be a fairly 'dry' topic. Key words: Hill reaction, NADP, light dependent reaction, light independent reaction, photosynthesis, chloroplast, cells, DCPIP, reduction, colour, expeirment, investigation, control

A resource aimed at post-16 biology students, this worksheet contains a list of written instructions for students to draw in order to recreate a diagram of the light dependent reaction of photosynthesis. This task can be given to the whole class and then a printed diagram of the light dependent reaction given out at the end of the activity for students to compare their drawing to; alternatively the class can be divided into two at the start of the lesson - half get a diagram of the light dependent reaction and are asked to describe each stage while the other half get this worksheet and are asked to draw a diagram; the two halves of each class can then be asked to verbally feedback to each other. This is a useful way of turning an otherwise dry topic into an involving and engaging activity. Key words: Photosynthesis, light, chloroplast, thylakoid, granum, photosystem, photolysis, NADP, ATP

An activity aimed at GCSE biology (age 14-16) students on the topic of stem cells. The activity includes a powerpoint presentation and a questionnaire word document. The powerpoint can be printed out on separate sheets of A4 and posted around the classroom for students to find - each slide has a suitable image together with clear explanatory text. The questionnaire matches the slides and so students can then match the answer to the relevant question. In terms of delivery, students can be paired up after they complete the activity and asked to verbally test each other on their knowledge of stem cells, checking that the information gathered has been understood. This can then lead into a whole class teacher-led discussion using the powerpoint slides to summarise the topic and check responses to each question. The activity includes coverage of the nature of stem cells, embryonic versus adult stem cells, IVF, uses of stem cells, ethical issues, tissue culture and medical treatments that are possible using stem cell therapy.
