A level Formative Assessment Tasks The assessment tasks have been created to support the Edexcel A level and International A level courses but can be adapted to support other examination boards. Each assessment starts with a brief introduction to engage the student. Students use their knowledge of the topic to complete the task. The task includes a guidance of what should be included and an indication to the grade associated with the knowledge, based on level of complexity. The resources are great to summarise a topic and can be completed in class or as a homework. Students can use their notes and books for support but the tasks should be answered in their own words to show understanding. I have found that these tasks: • Engage students and promote active learning. • They help students develop their course notes and prepare their revision. • Enables students of all abilities to progress and gives the teacher a way to access knowledge and understanding. • Enables misconceptions to be addressed. • Promotes the use of key scientific vocabulary to support answering examination questions. How to assess the task: Teacher assessed If the teacher is grading, I suggest taking a general approach. If students have attempted each section and the science is correct, I award the higher mark from the section. If not all the information is present or if not all of it is correct, award the lower grade from the section. Student assessed Students gain a lot from marking their own assessment or their peer´s. They should be able to justify the grade awarded. This can help develop appropriate feedback.

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 complete topic including 8 full lesson powerpoints and 7 worksheets. Each lesson includes bell ringer activities (starter activities) and plenary activities plus lots of retrieval practice.

There are also many exam-style questions to ensure students understand the material. I have included a range of different resources and tasks including pair and individual work. Students should be able to complete the following after the lessons: Describe the geotropic and phototropic responses of roots and stems and understand the role of auxin in the phototropic response of stems. State that the central nervous system consists of the brain and spinal cord andis linked to sense organs by nerves. Understand that stimulation of receptors in the sense organs sends electrical impulses along nerves into and out of the central nervous system, resulting in rapid responses Understand the role of neurotransmitters at synapses Understand the role of neurotransmitters at synapses Describe the structure and functioning of a simple reflex arc illustrated by the withdrawal of a finger from a hot object Describe the structure and function of the eye as a receptor Understand the function of the eye in focusing on near and distant objects, and in responding to changes in light intensity Describe the role of the skin in temperature regulation, with reference to sweating, vasoconstriction and vasodilation

8 lessons with powerpoints and worksheets covering the topic Gas Exchange in both plants and humans. This covers: The breathing system of humans including diagrams of the system to label Gas exchange and the alveolus. Students discover how alveoli are adapted to gas echange. Ventilation Core practical - breathing rate and exercise Smoking and how the lungs are damaged Gas exchange in the leaf Gas exchange mission - students are given access to the powerpoint to complete a spy mission linked to gas exchange (optional lesson) Core practical - investigating the effect of light on photosynthesis/respiration Each lesson contains a series of tasks to aid students learning including videos, discussion, labelling diagrams and exam questions.

A PDF worksheet, with answers, focusing on the limiting factors of photosynthesis. The experiment involves a student changing the light wavelength and investigating the rate of the reaction. Questions are similar to those found on exam papers relating to the topic. This resource is great for: In-class worksheet Pre/post-test Homework assignment Support work

Photosynthesis Topic with complete PowerPoint lessons and worksheets including lab activities. Each lesson involves a range of activities to promote interest and learning of the material. The content covers the following points: The word equation and the balanced chemical symbol equation for photosynthesis Understand how varying carbon dioxide concentration, light intensity and temperature affect the rate of photosynthesis Describe the structure of the leaf and explain how it is adapted for photosynthesis Understand that plants require mineral ions for growth, and that magnesium ions are needed for chlorophyll and nitrate ions are needed for amino acids Practical: investigate photosynthesis, showing the evolution of oxygen from a water plant, the production of starch and the requirements of light, carbon dioxide and chlorophyll

A PDF worksheet which focuses on the changes in an embryo from totipotent cells to cell differentiation. There are questions to challenge students understanding of these terms plus DNA methylation and acetylation. Answer sheet included. This resource is great for: In-class worksheet Pre/post-test Homework assignment Support work

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.

Practical activity - Investigating the changes in the population of a plant species along an environmental gradient. Transect samples are taken systematically in a linear pattern. In this investigation, you will use an interrupted belt transect to investigate the effect of the increase in height (altitude on a hill). Students record their results in the table and plot a scatter graph. A conclusion can then be drawn using their results.

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

A technique suggested in the book, Powerlearning. This is a revision technique with self-feedback. Students begin by reading each question and determining which ones they know the answer to and which ones they don’t. Independently, students determine what they know and what requires further study. Students answer the ones they know the answer to and then search for the answers they don’t know. Students then verify the answers they thought were correct. Students can fold the page over and use the questions for revision/retrieval practice.

A PDF worksheet which focuses on plant reproduction and the formation of the pollen tube. These questions are exam-style questions which check student understanding. Useful for in class activity, homework, retrieval practice activity. Answer sheet included.

A revision plan for students studying the Edexcel Biology Unit 4 module. The timetable can be edited to change the dates. Currently it is for the upcoming January 2023 exams. The timetable covers 9 weeks of intensive revision. Included in the pack is a detailed day to day revision plan to guide students through their revision. Also included are exam questions (with mark scheme) per topic area and worksheets. This has been a great resource for weaker students to help plan their revision and ensure they cover the content.
