This lesson covers the conditions needed for seed growth and provides the opportunity for an investigation into these conditions. Exam questions for the whole plant topic included.

This lesson starts with a recall of what a ‘gene mutation’ is before moving on to learn how gene mutations occur. Lesson concludes with an explaination on how mutations affects the formation of the polypeptide.

This lesson provides students descriptions and explanations on the effects of temperature on enzyme action. Fully resourced with worked examples.

Fully resourced lesson which looks at pH as a factor of affecting reaction rates.

Fully resourced lesson to teach how differing concentrations of enzymes and/or substrates affect enzyme action.

This resource covers both competitive and non-competitive inhibition. Fully resourced with lots of exam practise.

This lesson is fully resourced with video links included.

This lesson guides students into how to conduct this practical by measuring the product formed and the reactant used up. Illustrations and instructions are provided in the PPT.

This lesson covers the structure of ribonucleic acid (RNA) with specific reference to the structure and role of messenger RNA (mRNA).

This is a lesson based on student research where they are give source material to: outline the role of telomeres during DNA replication; outline the role of stem cells in cell replacement and tissue repair, and explain how uncontrolled cell division can result in tumour formation. All source materials are included.

This lesson covers the structure and properties of a phospholipids. The lesson also includes explanations as to how the structure and properties of phospholipids relate to their function in cell membranes.

This lesson outlines the main stages of cell signaling that can lead to: Secretion of ligands from cells; Transport of ligands to target cells, and binding of ligands to cell surface receptors on target cells.

First lesson for CIE iGCSE Biology on characteristics and classification of living organisms. The PPT gives examples of each of the seven characteristics along with a task sheet to give examples of the characteristics in both plants and animals. A summary crossword task for the plenary.

This lesson starts by comparing the nervous and endocrine systems. The students are then given a body outline of the endocrine system for which they need to research to identify each gland. The progress into researching the roles of each gland. The lesson concludes with a multiple choice quiz. Also supplied is a CIE specific assessment with mark scheme.

This lesson concludes the bundle on photosynthesis. It starts with a visual for students to analyse and decide if plants with photosynthesize and/or respire in the light and/or dark. This leads onto a discussion about plants not photosynthesizing in the dark because sunlight is a key factor. The are a series of slides demonstrating the classic graphs associated with each of the limiting factors with descriptions and explanations for the graphs. The lesson concludes with an assessment. The CIE exam questions are included in a separate document. Mark scheme is included.

This lesson provides opportunity for students to discover the two main groups of the animal kingdom: Vertebrates and Invertebrates. Students are given a ‘Who am I’ task to research the features of vertebrates which concludes with a whole class review. Students then are given the main groups of invertebrates and need to research the features of arthropods. The lesson concludes with an assessment task with CIE specific exam questions which also draw on learning from the previous lesson on classification. Students can then peer assess. This could also be a suitable homework activity. Mark scheme included.

This lesson starts with recall of the 7 nutrients with the intention to lead students into why carbohydrates, proteins and lipids are referred to as macronutrients . Their structures are illustrated, along with chemical structure to allow students to discover the elements glucose, carbon and hydrogen, and then why they are called macro/organic molecules. Later proteins are identified as having nitrogen. Further, the structures of starch, cellulose and glycogen are also identified. The lesson concludes with a crossword plenary activity.

This lesson starts by revisiting the location of the endocrine glands and then focuses on the pancreas and recalling it’s role. The PPT takes students through the release of insulin and glucagon from the liver, and the breakdown of glycogen in the liver. A quiz and review activity before introducing the concept of negative feedback. The plenary reviews the treatments of types 1 and 2 diabetes. Also included is a CIE specific assessment with mark scheme.

This lesson outlines the reflex arc in detail. The starts with a revisit to the three main types of neurones and students are then asked to investigate reflex actions, using torches (eye), and rulers on the knee and ankles. This leads to a discussion about how reflex actions are fast responses to stimuli and how this leads to survival in terms of evolution. The PPT shows the stages of the reflex arc and in the resources section there are alternative / additional activities that can be used depending on the learning styles of the class. For example, there are word cards that can be printed and students are given a word and they have to arrange themselves in the correct order of the reflex arc. There is also a cut and stick activity, if required. The lesson concludes with a revisit to the stages and students need to outline the stages of the reflex in the leg.

This lesson concludes the bundle of lesson on co-ordination and control. The starter activity requires students to recall the position and names of the dendrites and synaptic knobs on the neurone. This is used to later explain that this is the junction of a synapse. Students are given a diagram of the synapse to label, suing information from the PPT. The lesson concludes with a comprehension task to explain why impulses travel in one direction only. Answers are provided. This lesson also includes a CIE specific assessment, with mark scheme for assessmenet of the whole topic.
