Resource based on the edexcel 2016 spec (9-1) Note - This lesson does require additional worksheets from edexcel/ activeteach
Starter: Testing pupils prior knowledge of definitions by identifying definitions of key words.
Main: Includes all details about the nitrogen cycle, crop rotation and nitrogen fixing. Includes diagrams, videos, progress checks and tasks.
Plenary: uses the evaluation tree for pupils to assess their own learning.
Designed for AQA A-level Biology Unit 4 Section 3 - Nutrient Cycles. You will need counters and dice to play the game; the winner is the first person to visit all of the nitrogen reservoirs and return to the atmosphere. Students can use slide 2 on the PowerPoint to log their trips and - following a discussion with their competitors - be able to produce a complete diagram of the nitrogen cycle. They can then complete the exam questions (mark scheme included) to demonstrate their knowledge.
One of over 90 interactive PowerPoint presentations (Sets 1 - 7) covering the OCR Gateway GCSE specification. Already used in hundreds of UK and international schools.

Currently, the TES store for Premium Resources only allows a PowerPoint preview to consist of one content slide plus the Cover Slide and End Slide. Therefore, we have included a full set of slide images (.png files) to allow you to appreciate the full content of this presentation - you do not need to retain these images after download - just keep the .pptx file.
A worksheet aimed at A-Level Biology students which provides a neat summary of the key points in the Nitrogen Cycle. The resource covers naming of key compounds (nitrate, nitrite, ammonia, ammonium ions), deamination, ammonification, decomposition and denitrification. The resource also has two 'challenge' questions for more able students to apply their knowledge.
Key words: Nitrogen cycle, ammonia, nitrite, nitrate, ammonium, deamination, ammonification, decomposition, denitrification
An activity aimed at A-Level Biology students. This activity involves a series of statements that can be given to a class at the start of a lesson with the instruction that they draw the nitrogen cycle based on this information. Students should initially do this in pairs but can then be teamed up in larger groups to show, discuss and explain their own diagrammatic interpretations of the nitrogen cycle. Finally, the whole class can be brought together to discuss the best way of joining these statements together into an agreed nitrogen cycle.
Key words: Nitrogen, cycle, ammonification, nitrification, denitrification, saprobiont, decay, symbiotic, rhizobium, azotobacter, decomposition, photosynthesis, respiration, combustion, fossilisation, assimilation, feeding, herbivore, carnivore, carbonate
You have two power points covering all aspects of the GCSE Biology syllabus covering the Carbon and Nitrogen Cycles. They are aimed at Higher Tier students but can be used with a good "intervention" group.
The power points are separate so you can use in different lessons. Text is full of scientific terminology and includes diagrams and pictures to help with explanations.
Thank you for taking the time to look at my resource and I hope you find it beneficial.
Please feel free to leave feedback and to 'follow me' so as not to miss out on future helpful resources.
A worksheet of questions related to the nitrogen cycle which students are required to research. Each series of questions is divided into separate categories according to which part of the cycle they relate to: nitrogen fixation, nitrification, ammonification, denitrification, etc. A useful worksheet to issue at the start of a topic as background research for students to gain familiarity with the key ideas.
Keywords: Nitrogen, cycle, ammonifiication, denitrification, nitrification, saprobiont, decay, fixation
A worksheet aimed at A-Level Biology students which sets out a series of research tasks for students to learn about the nitrogen cycle. A good resource to use at the start of this topic as homework or in class by dividing out each piece of key research among the class. Internet websites are listed which provide useful animations and information for students to use as they complete their research.
Key words: nitrogen cycle, deamination, ammonification, denitrification, nitrification, nitrogen fixation, nitrogen, ammonia, nitrite, nitrate, ammonium ions, symbiotic
An engaging and detailed lesson presentation (31 slides) that looks at how nitrogen is cycled and focuses on the different bacteria who play key roles in this cycle. The lesson begins by exploring why nitrogen is so critical for living organisms for the synthesis of DNA and proteins. Students are introduced to nitrogen-fixing bacteria to start and challenged to use their knowledge of interdependence to state the type of ecological relationship that is formed between them and the leguminous plant that they live on. Each stage of the cycle is complimented by a diagram highlighting that part so students are able to visualise how the cycle comes together. Time is taken to ensure that students recognise that any non-leguminous plants can only absorb nitrogen when it is nitrates form from the soil. Moving forwards, students will meet decomposers and nitrifying bacteria and again be shown where their function fits into the cycle. As the final part of the learning, students are challenged to consider what else is needed in order for this to be a cycle and will meet the denitrifying bacteria as a result. Progress checks, in a range of forms, have been written into this lesson at regular intervals so that students can assess their understanding and any misconceptions can be immediately addressed.
This lesson has been written for GCSE students, but could be used with A-level students who want to have a recap before extending their knowledge further.
This presentation was created and delivered for A level students studying the nitrogen cycle in the ecosystems topic however the resources are still relevant and applicable to GCSE and the vocabulary could be easily adapted. The resource is a clear detailed step by step guide to the nitrogen cycle each stage is clearly described and explained including nitrogen fixation ammonification and so on. it also later on shows ethical considerations in ecosystems including eutrophication.
Lesson used for an observation and was highly praised. Full lesson about the nitrogen cycle which really breaks everything down but does not neglect suitable challenge and exam focus for GCSE students.
Lesson includes full presentation; circus activity posters, worksheets and support sheets; starters and plenaries; extension work; mark schemes; literacy activities; and a full lesson plan.
A thorough and complete lesson plan, resources, answers etc in detailed user friendly ppt. which could easily spread two lessons, a circus activity on nitrogen cycle (adapted from another TES resource. Lots of exam questions for application tasks and worksheets included in ppt.
Carbon and Nitrogen cycle includes but taught in a slightly different way - to suit new A-level demand.
