worksheets: food webs, pyramids of numbers and biomass, energy loss in chains, pesticides, bioaccumu

High quality differentiated KS3 Biology worksheets with answers from Barclayfox. These worksheets cover: Good selection of worksheets with answers, covering pyramids of numbers, calculating biomass and pyramids of biomass, drawing both, energy loss in food chains and webs, pesticides and bioaccumulation. Differentiated for the able and less able. Save yourself the hours needed to prepare a differentiated resource with answers as I have already spent those hours preparing this for my students and improving it over many years. There is nothing for you to do but give it a very quick look through and familiarise yourself with it and photocopy it for your students. As teachers we all work ridiculously long hours each week.

NEW AQA GCSE Trilogy (2016) Biology - Selective breeding

NEW AQA GCSE Trilogy (2016) Biology - Selective breeding

This lesson is designed for the NEW AQA Trilogy Biology GCSE, particularly the 'Inheritance, variation and evolution' SoW. For more lessons designed to meet specification points for the NEW AQA Trilogy specifications for Biology, Chemistry and Physics please see my shop: https://www.tes.com/teaching-resources/shop/SWiftScience The task begins with pupils being asked to think > pair > share the specific characteristics that farmers might find favourable in cows, crops, chicken and sheep. The next activity involves pupils watching a video on selective breeding and how this process works, pupils will need to answer questions as they watch the video. The work can be assessed when they finish using the mark scheme provided. Pupils will now understand the process of selective breeding, the next task requires pupils to choose two dogs from a selection of dog breeds (pictures provided) to breed together in order to produce offspring with the traits the student would like. They can sketch a flow diagram to demonstrate how thus process occurs. The next activity is a worksheet on chicken breeds, once students have completed they can use the mark scheme to self or peer assess their work. The final activity focuses on the problems with selective breeding, pupils are provided with some information which could be tag-read as a class. This can then be used to answer some quick-check questions. Once the questions are complete this work can be self-assessed using the answers provided. The plenary task is for pupils to use a list of key words to write a summary sentence about what they have learnt from the lesson. All resources are included at the end of the presentation. Thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated :)

Transfers in food chains, energy loss, pyramids of numbers and biomass, bioaccumulation, pesticides.

A complete, and ready to deliver, high quality KS3 lesson from Barclayfox. (For USA - this lesson is for use between 6th to 8th grade). This is a complete lesson from start to end, you do not need to spend many hours carefully planning, creating, resourcing and improving this lesson after each use. I have already spent those hours preparing this lesson for my students and improving it over many years. This is a very high quality lesson. There is nothing for you to do but give it a quick look through and familiarise yourself with it. Lesson objectives: * Represent food chains using Pyramids of numbers. * Describe how energy is lost as it transfers down the food chain. * Calculate biomass and create pyramids of biomass. * Explain bioaccumulation of pesticides and the effect. This carefully crafted lesson is over 30 slides long, and is full of these learning activities: * Notes to help the teacher. * Starter - complete the food web. * Starter - simple task where students self-assess against the objectives. * Matching game - answers are provided. * Role play - spread of pesticides up the food chain. * Questions – all answers are provided. * Peer marking & Self marking opportunities * Up and about activity - role play * Theory slides (carefully sculpted, interspaced with learning activities, not ‘death by powerpoint’). * Activity sheet - with answers - simply print it off for each student if required. * Play ball opportunities * Video clip links - several (carefully selected – this alone can save you 20+ minutes of searching). * Paired work activities – all answers are provided. * Homework - optional / at your discretion using the activity sheet. * Scientific Literacy activity. * Scientific Numeracy activity * SMSC opportunity - use of pesticides & effect on organisms. * Student self-assessment versus objectives activity – so learners can judge for themselves how much they have learnt. * Extension activities – just in case additional activities are required. As teachers we all work ridiculously long hours each week.
