The lesson starts by consolidating learning on diffusion and then introduces the concept of diffusing water. The osmosis investigation in potato chips leads learners through the planning of a trustworthy investigation through to a thorough evaluation in terms of reliability, accuracy and precision. There are particle diagrams for visualisation of moving water particles and keywords needed for explanation of the results. The lesson concludes with a plenary activity, comparing diffusion with osmosis. The next lesson in which looks at the importance of osmosis in living systems is supplied with CIE specific exam questions and mark schemes.

This final lesson on cell transport starts with a review of osmosis with an exam style question and bulleted answers. The main body of the lesson explores active transport as a concept and the looks at the importance of maintaining root pressure in plants and absorption of nutrients from the gut.

This is the first of two lessons in the bundle and introduces ideas of diffusing particles and the laws of diffusion. The lesson starts with the Jaws movie trailer to prompt thinking about how the shark was a able to smell it’s prey. There are demo and practical activity opportunities to demonstrate diffusion in gases and liquids whilst simultaneously introducing ideas about factors affecting diffusion rate. One of the videos looks at the effect of surface area on diffusion rate using agar jelly, but does not show the results. This could be an opportunity for students to try for themselves. The lesson concludes with an exam question.

This lesson introduces the idea of enzymes as biological catalysts and the differences between anabolic and catabolic reactions. The lesson starter promotes thinking about the film ‘The Fly’ and how flies digest their food externally using digestive enzymes. There are a series of YouTube videos and consolidation quizzes. The lesson concludes with a CLOZE task on the importance of enzymes in living organisms.

This lesson starts by revisiting the microscope; the start task focuses students on a labelling task to recall microscope parts. The main body of the lesson, reviews plant and animal structure before introducing the concept of being able to view them under the microscope. Worksheets are provided as guidance on the procedure to extract cheek and onion cells. These sheets can be printed or displayed on the whiteboard. Students finish off by drawing labelled cell diagrams with a focus on scale and magnification - a preliminary to the next lesson which is about calculating maginification.

This lesson starts with a KS3 recall task on basic plant and animal cell structure. Students are then introduced to mitochondria and ribosome organelles, with a short summary task for each one. The lesson then progresses into organism organisation from cells through to the complete organism in plants and animals with a cut and sticking activity for them to complete. The final learning activity is looking at three organ systems; students are given some resource material which they should analyse in order for them to understand the organisation of the three systems. Some of the PPT slides have been taken from other sources and adjusted for the purposes of the CIE syllabus. A CIE specific assessment is also provided with mark scheme.

This lesson starts with a recall of the differences between cross pollination and self-pollination and then the process of fertilisation. The lesson then covers the effects of cross and self-pollination. Fully resourced.

In this lesson, students identify the reproductive organs and describe their roles in fertilisation. They then progress to describe and explain the features of the gametes, finishing with outlining stages of fertilisation and the formation of a zygote. Videos and exam questions included.

This lesson starts with a review the meaning of the term ‘species’ and then students learn of the three domains: Archaea, Bacteria and Eukarya. The lesson progresses to look at the characteristics of the four Eukarya Kingdoms, finishing off with an outline how viruses are classified.

This lesson identifies and describes the functions of the reproductive organs of insect and wind pollinated flowers. Students then identify differences between wind and insect pollinated flowers and distinguishes between two different types of pollen grain and describes the process of pollination. The lesson then progresses to look at the differences between cross pollination and self-pollination. Fully resourced.

In this lesson students recall the process of mitosis and learn how it works. Students then learn how meiosis results in the formation of haploid cells. The lesson then progresses to explain how mitosis and meiosis are used in the formation of an embryo. Fully resourced. Exam questions included.

This lesson covers the principles of selective breeding using examples: Disease resistance in rice and wheat; Strong maize; Increased milk yield in dairy cattle.

This lesson starts with a review of different classes of drugs and thenwhat antibiotics are used for. The lesson then explains how they work with an analysis of how antibiotic resistance can occur and how we can stop the spread of antibiotic resistance. Fully resources with videos and exam questions.

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.

This lessons cover the explanation of the causes of phenotypic variation and the differences between discontinuous and continuation in terms of genetics. The lesson covers the T-Test to compare two difference samples of variation including worked examples.

This lesson covers the factors that can affect the size of populations and the causes of natural selection.

This lesson covers the environmental factors can act as stabilising, disruptive and directional forces of natural selection and how selection, the founder effect, genetic drift and the bottleneck effect may affect allele frequencies in populations.

This lesson covers how bacteria become resistant to antibiotics as an example of natural selection.

This lesson teaches the principle to calculate allele and genotype frequencies in populations.

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.
