Through this fully resourced lesson students will explore the environmental and genetic causes of kidney disorders. They will first categorise human features as environmentally or genetically determined. They will then describe common symptoms of kidney disorders through a role play activity. In the last part of the lesson students will consider factors that can affect kidney function. Students will also have the opportunity to apply their knowledge and understanding to exam style questions.

Through this fully resourced lesson students will analyse molecular and biogeographical evidence for evolution. They will first through a range of differentiated starter activities compare amino acid sequences between different species as evidence for evolution. They will then interpret graphical data showing comparative molecular biology. They will finish by exploring how the geographic distribution of species provides evidence for evolution. Students will also have the opportunity to apply their knowledge and understanding to exam style questions throughout this lesson.

Through this fully resourced lesson students will describe the terms species fitness and adaptation through a range of differentiated starter activities requiring reading comprehension. They will then compare mimicry and camouflage by looking at a number of different examples including how antibiotic resistance shows evolution by natural selection. They will then finish the lesson by exploring spandrels as a consequence of adaptation. Students will also have the opportunity to apply their knowledge and understanding to exam style questions throughout this lesson.

Through this fully resourced lesson students will consolidate your understanding of evolution by first developing their understanding of the concept of artificial selection with examples. They will then move on to recall the principles of evolution by natural selection and then finish by considering the different types of evolutionary evidence that exist. Students will have the opportunity to apply their knowledge and understanding to exam style questions throughout this lesson.

Through this fully resourced lesson students will explore the role of the pituitary gland in maintaining homeostasis. Students will first identify the location of the pituitary gland and hypothalamus, they will then describe why the pituitary gland is sometimes called the ‘master gland’, before finally explaining how the nervous systems and endocrine systems work together in the pituitary gland using ADH as an example. Throughout the lesson students will also have the opportunity to apply their knowledge and understanding to exam style questions.

Through this fully resourced lesson students will determine how steroid and amino acid hormones initiate a response. They will first describe what is meant by a steroid, they will then recall examples of steroid and non-steroid hormones before comparing the action of steroid and non-steroid hormones. Throughout the lesson students will also have the opportunity to apply their knowledge and understanding to exam style questions.

Through this fully resourced lesson students will determine the role of reproductive isolating mechanisms in speciation. Students will first define the term species and speciation and look some examples of hybrid organisms. Students will then describe the two types of reproductive isolating mechanisms; prezygotic and postzygotic isolation. Students will finally interpret exam style questions related to reproductive isolating mechanisms.

Through this fully resourced lesson students will explore the main patterns shown by evolution. Students will first recall the main types of evidence that exist for evolution and speciation, they will then identify and describe the three main evolutionary patterns including adaptive radiation, coevolution and convergent evolution. Students will finally differentiate between the gradual and punctuated equilibrium models that explain the tempo of evolution. Throughout the lesson students will also have the opportunity to apply their knowledge and understanding to exam style questions.

Through this fully resourced lesson students will explain the role of the thyroid and parathyroid glands. Students will first identify the location of the thyroid and parathyroid glands, they will then describe the role of the main hormones secreted by the thyroid and parathyroid before finally determining the role of the thyroid and the parathyroid in homeostasis. Throughout the lesson students will also have the opportunity to apply their knowledge and understanding to exam style questions including a question on hypothyroidism and hyperthyroidism.

Through this fully resourced lesson students will determine the role of the hormones glucagon and insulin in maintaining homeostasis. Students will first describe the main functions of the pancreas, they will then explain how insulin and glucagon maintain homeostasis before finally exploring the symptoms and treatments of diabetes. Throughout the lesson students will also have the opportunity to apply their knowledge and understanding to exam style questions.

Through this fully resourced lesson students will discover the role of the main adrenal hormones in responding to stress and reducing inflammation. Students will first describe how our body responds to stressful situations in the fight or flight response, they will then explore the adrenal hormones and their roles before finally responding to exam style questions relating to the adrenal glands.

Through this fully resourced lesson students will determine allele frequencies based upon the Hardy-Weinberg principle. This lesson is an introduction to this concept therefore the calculations are quite simple and the main aim is for students to understand the concept of the Hardy-Weinberg principle. My following lesson ‘Calculating Allele and Genotype Frequencies’ explores calcuations in much greater depth. Students will first recall the terms allele, homozygous dominant, homozygous recessive and heterozygous which they should have already covered in a previous topic before being able to access this lesson. Students will then be introduced to the Hardy-Weinberg principle and the conditions it requires. Students will then learn how to calculate simple allele frequencies using the equation p+q=1. Throughout the lesson students will also have the opportunity to apply their knowledge and understanding to exam style questions.
