This resource covers the content for the lesson SB9a - Ecosystems. This resource starts with a visually engaging slide with the date, title and two starter questions, an easier question (green) and more abstract question (orange) to stretch and challenge. Learning outcomes are displayed at the start of the PowerPoint and can be seen throughout and referred back to reinforce the learning journey. Key content/words are highlighted in red text throughout. You will find similar green and orange questions scattered throughout the resource to strengthen and develop understanding. The lesson ends on an exam style question to allow students to apply their learning. This resource is aimed to be able to be used by an teacher, specialist, or non-specialist to deliver this portion of the curriculum accurately and effectively.

This fun resource gets pupils answering clues and questions to complete the cross words on the topics cell structures and specialised cells. Excellent activity to set as a homework task or consolidation task during lesson.

Pupils have to find the key words in the word search and then insert them into the associated gap fill exercise.

differentiated puzzles on absorption in the digestive tract.

This resource includes a word search and a kryptogram.

This resource guides a-level biologists through the experiments that provide evidence that sugars are carried in the phloem. The concept of ringing experiments are explored before discussing its conclusions. We then move onto how radioactive tracers can be used and look at the conclusions drawn from these experiments. Other evidence such as aphids and cutting of phloem are also considered. Stretch, challenge and lateral thinking questions are embedded throughout alongside carefully selected visuals.

This resource guides a-level biologists through how the products of the light-dependent reaction of photosynthesis can be used to synthesise organic molecules in the light-independent reaction. The Calvin cycle is explored before discussing how the chloroplast is adapted to execute this cycle. Stretch, challenge and lateral thinking questions are embedded throughout alongside carefully selected visuals.

This resource introduces a-level biologists to the concept of photosynthesis. The structure of a lead and how is adapted to photosynthesis is covered before looking at what is happening inside the chloroplast. The 3 main stages of photosynthesis are then introduced. This lessons is important preparation for the following lessons on the light dependent and independent reactions of photosynthesis. Stretch, challenge and lateral thinking questions are embedded throughout alongside carefully selected visuals.

This resource guides a-level biologists through the structure and function of homologous chromosomes and how genes are arranged along them. Stretch, challenge and lateral thinking questions are embedded throughout. This is a resource been made to be picked up and used by any teacher. AQA Biology

This resource guides a-level biologists through species diversity and how its measured. Stretch, challenge and lateral thinking questions are embedded throughout. This is a resource been made to be picked up and used by any teacher. AQA Biology

This resource guides a-level biologists through the factors thatcan affect the speed of an impulse, including the refractory period and the all-or-nothing principle. Stretch, challenge and lateral thinking questions are embedded throughout. This is a resource been made to be picked up and used by any teacher. AQA Biology

"Why can’t revision be fun?" A question I used to hear before any formative or summative assessment. Truth is, revision can be fun. Why not give this game of snakes and ladders a go. The board is riddled with questions from the topic CB1 and players must wind their way through the board and up the ladders in order to win. But be careful, there are some sneaky snakes and tricks boxes out there too to catch you out. The first to the finish line wins. My students loved this game. Its interactive, competative and effective. Good luck and enjoy! :)

This resource guides a-level biologists through gas exchange of boney fish. The structure of the gills is explored whilst explaining how the counter-current flow system of gas exchange optimises the diffusion of oxygen. Stretch, challenge and lateral thinking questions are embedded throughout.

This resource guides a-level biologists through the structure and function of the 3 different types of RNA found within eukaryotic cells. Stretch, challenge and lateral thinking questions are embedded throughout. This is a resource been made to be picked up and used by any teacher. AQA Biology

This resource guides a-level biologists through gas exchange in the leaf. The idea of compensation point is dicussed to get students thinking about the dynamic level of gas exchange taking place in a leaf before we explore its structure and how it meets the requirements of gas exchange. Stretch, challenge and lateral thinking questions are embedded throughout.

This resource guides a-level biologists through the site of gas exchange where the structure and role of the alveoli is discussed in depth. Stretch, challenge and lateral thinking questions are embedded throughout alongside carefully selected visuals.

This resource guides a-level biologists through the role of the villi in absorption of the products of digestion. The process of co-transport of glucose across the ileum is explored also. Stretch, challenge and lateral thinking questions are embedded throughout. This is a resource been made to be picked up and used by any teacher.

This resource guides a-level biologists through the need for a gas exchange system in mammals before exploring the macro to the microstrucure of the lungs. The lungs, trachea, bronchi, bronchioles and alveoli are discussed. Stretch, challenge and lateral thinking questions are embedded throughout alongside carefuly selected visuals.

This resource guides a-level biologists through the structure of a Prokaryotic cell and how it compares to a Eukaryotic cell before exploring the basic components of a virus. Stretch, challenge and lateral thinking questions are embedded throughout. This is a resource been made to be picked up and used by any teacher.

This resource guides a-level biologists through the nature of active transport with a few example from within the specification. Stretch, challenge and lateral thinking questions are embedded throughout. This is a resource been made to be picked up and used by any teacher.
