This resource covers everything concerning genetics and sex linkage, using genetic diagrams to predict and explain the results of monohybrid crosses.

This lesson covers interpretation and construction of genetic diagrams to explain and predict results of dihybrid crosses involving autosomal linkage and epistasis,

This resource builds on previous learning of dihybrid and monohybrid crosses to apply the Chi-square test and to use the Chi-square test to analyse the results of crosses (B-A).

Lesson covers the following diseases in terms of genes, the proteins they encode, and the phenotype expressed: Albinism; Sickle Cell Anaemia; Haemophilia; Huntingdon’s Disease. The lesson also cover the role of gibberellin in plants and effects of the two alleles that code for it’s functional enzyme.

This lesson recalls Darwin’s Theory of Evolution and discusses how DNA sequences can be used to show evolutionary relationships between species. The lesson then looks at how speciation occurs as a result of Allopatric speciation and Sympatric speciation.

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 covers the type of protein that enzymes are categorised into and teaches students how to describe and explain how enzymes work in terms of: the active site; the enzyme–substrate complex; lowering of activation energy, and enzyme specificity. The lesson then progresses into the differences between the lock-and-key hypothesis and the induced-fit hypothesis. Fully resources and exam questions.

This lesson is fully resourced with video links included.

This lesson starts with recall the structure of proteins and the structure of a gene then to explain how genes code for the amino acids in a polypeptide. The lesson finishes off with principle of the universal genetic code.

This lesson starts with recall of KS4 mitosis, the introduces the concept of the complete cell cycle including Interphase: Gap 1; Synthesis, and Gap 2. All stages of mitosis is covered including the roles of involved organelles. Lesson concludes with a quiz to identify the stages of mitosis from micrographs.

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 is the class practical outlined in the CIE specification. The lesson starts by recalling how to calculate surface area and volume, calculating surface area to volume ratios and then the Investigation into diffusion in different sized cells using agar blocks. The lesson concludes by explaining the relationship between cell size and diffusion rate.

This less starts with a recall the structure of cell membranes and then progresses into how the fluid mosaic model of membrane structure is used to explain the structure and properties of cell membranes. Later the lesson looks at how the components of the membrane contribute to it´s physical and chemical properties. All resources included.

This lesson starts with KS3 recall of the similarities and differences between asexual and sexual reproduction. It progresses to describe the advantages and disadvantages for both types and how some organisms can reproduce using both methods. The lesson uses a YouTube video link for students to summarise into bullet notes. The transcript is also provided for EAL learners.
