This lesson provides students with the opportunity to analyse the relationship two variables and how biotic and abiotic factors affect distribution and abundance of species. Fill worked examples of Pearson’s Linear Correlation included.

This lesson looks at the mode of action of the Venus Fly Trap and how it responds to stimuli. the lesson then progresses into the roles of hormones gibberellins and auxin. Lots of visual diagrams to illustrate concepts. Biofactsheets on plant hormones and CIE specific exam questions and mark scheme provided.

This lesson provides an opportunity to explore features of the 5 kingdoms of life and viruses. Students are provided with a 5 kingdom tree to glue into their books and they are given questions to answer about it. They are then provided with a cut and stick activity to identify organisms within each of the 5 kingdoms. The lesson ends with a 10 question quiz. Also included is a summary assessment sheet that can be used as a homework activity.

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 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 research task to find out the role of the fovea, then explores how long and short vision is accommodated for by the eye with diagrams for students to label. The final part of the lesson is on the potision of rods and cones and what they do. A true/false quiz for the plenary. Also included is a CIE assessment with B-A* questions and mark scheme.

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 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 moves on to revisit the learning from the previous lesson on using a microscope to view onion and cheek cells. Students are introduced to a series of items that have been magnified and they are asked to identify each one. Students are then showed an animation from CellsAlive to rank magnified specimens in order of size. The lesson concludes with an introduction to the magnification formula, micrometers and unit conversions, together with some magnification calculations using unit conversion. Also included is a CIE specific assessment with the mark scheme.

This lesson covers all the learning objectives for plant homeostasis as per the CIE specification. It focuses on the structure and function of stomata, how they are able to open and close during their daily rhythm and the use of abscisic acid and calcium during times of water stress. Lots of visual diagrams outlining the stages of the process. CIE specific exam questions are also included.

These two PPT’s cover all glands and the hormones they produce. They can be used for all exam boards and their specifications. Both PPT’s contain many visuals and cover the consequences of the deficiency of certain hormones on the body. The PPT’s also cover the differences between exocrine and endocrine glands, including the 2nd messenger model for for cell signalling.

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.

This lesson covers all stages of respiration with an interactive PPT and other resources to support stuents. The lesson starts with a review of mitochondria structure, ATP role and structure and the introduction of the different types of phosphorylation. The lesson then progress through the four stages of respiration including a running total of ATP used/produced at each stage. Also supplied are Biofact sheets and CIE exam questions.

This lesson covers the absorption spectrum of chloroplast pigments and the action spectra for photosynthesis. If then takes the learners through the process of how to use chromatography to separate the pigments. A Biofact sheet is also included in the resources.
