This is for Edexcel A level Biology context-led course. There is information and questions to answer including an exam-style question. I have used and modified some slides from hmc keating's power point on this topic ( on the TES website), and have added some more to suit the teaching of the Edexcel course. Thanks to hmc Keating. The blog link has a little etra about the Red Queen theory of evolution.

Why choose this resource? It has easy to follow instructions that individual groups of students can use to extract DNA very successfully. It also has questions suitable for A level or Higher Biology students or a "good" class of Biology Triple GCSE students. Practical guide would be very useful for non-specialists.

This was used with a low-ability Yr 10 group for GCSE work. Could be adapted for other groups/KS3. Also useful for assessing ability to analyse scientific results.

This has a handy way to help students memorise the Kreb's cycle. There are diagrams illustrating various steps in respiration with questions for students to answer. This is useful to review or revise the topic. There is a power point with answers and a word document with answers to allow some differentiation in the way students mark their work.

This is a whole-lesson resource. Most diffusion practicals involve observation only - this resource asks students to measure and calculate. Further it has a set of results, obtained by real Year 7 students and a graph of their results. This is so all students have a standard set of results to compare their own results with and a standard set to interpret, so you can check their understanding. This resource also challenges students to use their knowledge of particles to help them analyse the results of comparing two different concentrations of acid.

Choose this resource to liven up your lesson on plant diseases. It has a practical that works and delighted some teachers recently at a workshop. It has differentiated tasks to extend the more able. It reviews work on fungi and viruses.

This has back-up materials for the required practical (AQA GCSE) on measuring the rate of photosynthesis. Ideal for non-specialists in Biology and for newly qualified teachers. It contains tips on how to get good results and results of a practical in case your class does not get any data. There are differentiated worksheets which ask about rate of reaction - as this is a requirement now at GCSE.

Here are two lessons of resources for the new science GCSE ( 2016) unit on Health and Disease. Written for the AQA scheme but will apply to other boards. Initially there are pictures to provoke thoughts about health and what health means.There is a differentiated literacy activity on different types of disease. It also contains a practical activity illustrating how diseases are communicated, which can be extended to allow students to analyse the data collected and develop mathematical skills. Finally there is some information and there are differentiated activities about the interactions between diseases. The resource contains a power point and accompanying lesson plan. There are instructions for the practical simulation and a worksheet about types of disease.

Why choose this resource? It provides material for a whole lesson. It has instructions for a piece of practical work that the students will enjoy and helps them learn skills such as manipulation and dissection. The practical work is directly linked to the task of learning the parts of the flower. It has some clear diagrams that help explain pollination and some great pictures. It has differentiated tasks and a homework!

This resource is good value as it has technician lists, practical instructions, background material and worksheets for 5 lessons/activities on acids and alkalis. It is very suitable for new teachers or teachers teaching out of subject area who may like some new ideas/resources. It fits the new KS3 science section on the pH scale and neutralisation.

Why choose this resource? It has the most brilliant way for students to see stomata - you will never use a different method again! Apart from which there are ready made plan diagrams of a leaf for students to annotate and 3 different presentations of information for them to interpret depending on their ability. The power point explains meristems which has appeared in the AQA trilogy, ( never seen it at GCSE before!)

Resources for teaching this new part of KS3. It contains instructions for a demonstration and optional class practical with material for a whole lesson. The work is differentiated and aims to teach some practical skills as well as the concept. Contains differentiated worksheets, extension material and a power point.

Ideal if you want a quick homework and/or review of work done on reflection and refraction to see if students have understood basic principles. There is an answer sheet for self-marking or peer-marking and this is also presented on a power point - time-saving for the teacher!

Differentiated homeworks. Ideal for new teachers or busy teachers as they have answers on a presentation and in a word document suitable for self or peer assessment to save you marking time. Suitable for KS3 students.

3 homeworks on different topics with differentiation for KS3. Great for new teachers or busy teachers as they come with answers to questions that can be displayed as a power point for peer-assessment or self-marking.

Ideal for new teachers and/or busy teachers. Three different homeworks here. This resource saves time as it has answers to the questions so that the students can mark it themselves or peer-mark. One homework includes approx GCSE grades to give an idea of attainment. All homeworks have an extension question.

A useful way to assess student's understanding of the essential key words needed to answer questions on Evolution. Students match the key words to the meanings. Includes an answer sheet for self-assessment or peer-marking.

This resource tests students' application of knowledge and analysis as well as delivering the essential knowledge needed. The power point and worksheet were 5 star-rated resources when posted separately on TES. They are combined here with a lesson plan an additional worksheet and an answer sheet to give enough material for a whole lesson. There are also ideas for demonstrations as starters for this lesson.

Knowing how to make slides and how to use a microscope is essential information needed for the new GCSE Science/Biology. This resource has instructions and assessment criteria for a peer-assessed practical. Reduces marking time and allows students to practise this core practical in a directed way. Answers to the short written test are included. Clearly indicates areas for improvement to the students and to you. I have used this very successfully with several classes of varying abilities. Resource includes,: Practical instructions for the student. Assessment criteria. Lesson plan. Written test. Power point slide with pictures for guidance and answers to the written test.
