A level lesson which focuses on reasons for speciation to occur. The powerpoint is a complete lesson which contains individual student tasks to aid note taking and examination style questions.

An A level lesson focusing on productivity of plants. Students are introduced to the terms GPP and NPP plus the calculation. I have included an exam question with markscheme.

We have started using this technique in our science department to allow students to highlight areas where they make mistakes. This could be due to misreading questions; not understanding the material; not understanding the questions; calculation questions or not using correct terminology. Once our students were aware of where the mistakes were being made, we gave them focused targets and it has helped improve their performance.

This resource focuses on Edexcel specification link 6.11 It introduces the different types of immunity. There is a video resource and questions to check understanding. The information cards can be printed and put around room for students to collect information to make it more interactive. I was short on time so I went through them on the board as students made their own notes.

A level Biology - Control of the Internal Environment 4 Powerpoint lessons covering: The principles of mammalian hormone production by endocrine glands The mode of action of hormones The production of metabolic waste Osmoregulation Kidney structure and function Urea production Thermoregulation

A series of three lessons which focuses on A level content from Edexcel Specification but can be applied to other specifications. Content includes Understanding what a chromatid is and how it forms The cell cycle and what occurs at each stage Control of the cell cycle The stages of mitosis Cytokinesis Cell division in both animal and plant cells Mitotic index

Learning Objectives: Understand how to determine the time of death of a mammal by examining the extent of decomposition, stage of succession, forensic entomology, body temperature and degree of muscle contraction. You will need internet access This is an interactive forensics activity. It begins with a body that has been found within a field. Students use their knowledge of forensics plus the information provided on the site to determine the time of death. There is no correct time here but hopefully students will be able to justify their answer. Students are able to study entomology results, rigor mortis, body temperature, digestive contents, blood results plus other facts such as clothing and exercise. Students will need a copy of the police report to complete and graph paper. Students will be given a link to access the task. You do not need to provide an email address or have a google account to access the material. The task can be completed on laptops, tablets and mobile phones.so they can be set as homework or used in cover lessons.

A PDF worksheet of a dichotomous key to identify invertebrates. This can be used as an independent learning task where students can work through the clues in the key. Answer sheet included.

A useful revision tool for students preparing for the Edexcel IGCSE Chemistry exam Summer 2022. The 14 paged booklet includes the specification points for students to plan their revision plus details of core practicals they could be tested on. There are also a large range of revision questions to test student knowledge. Great for class revision or homework. Supports students with revision on specific topics.

An A3 PDF worksheet which summarises each of the core practical methods to gain 5 marks in the first question on unit 3. It also supports the experimental design question in unit 1 and unit 2 I have also included the biotic and abiotic factors to control, where appropriate, and the effect of not controlling this on the experiment.

A practical investigation that enables students to determine whether light intensity affects the population of plants in 2 areas, one being shaded and the other with light. Students randomly generate coordinates for an area marked out. I have suggested using 2 tape measures at right angles. Quadrats are then placed at the sites and the plants are counted. Students then use the data to estimate the total plant population.

A pdf worksheet focusing on the experiment with water plants with and without light. Also contains respiring organisms. The experiment uses bicarbonate indicator which changes colour in the presence of low and high concentrations of carbon dioxide. The experiment is explained and there are exam-style questions to promote understanding. Answer sheet included. Suggested uses: in class activity; homework task; revision task

60 flash cards with exam-style questions for students to prepare. The questions cover all of the topics in unit 5 and give students a chance to prepare model answers for each of these in preparation for the A level exam. Once completed, my students check their responses with the model answers and then laminate and use as a revision tool.
