This lesson revisits KS4 learning of synapses and moves on to the stages involved in the passages of neutrtransmitters across the cleft. Also covered is unidirection, summation and inhibition, followed by the neuromuscular junction and a comparison between both the cholinergic synapses and neuromuscular junctions. The lesson also includes details on how drugs affect neurotransmission (not required for CIE). Lots of visuals and videos to embed learning. Details of the T-tutbule system and sacoplasmic reticulum and included in the next lesson on muscle contraction. Exam questions also 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 starts with recall of how resting potential is maintained and the functions of the sodium potassium pump and voltage gated channels. The lesson then progresses into the the generation of an AP and the all or nothing response. Repolarisation and hyperpolarisation is covered. PPT is visual and includes videos to embed concepts. All resources are included in the PPT.

In this lesson, students learn about the stages of the menstrual cycle and the changes in the uterus and ovaries during the menstrual cycle. For higher tier students, they also learn of the role of hormones FSH, LH, progesterone and oestrogen in controlling the menstrual cycle. Lots of resources, activities and exam questions.

This lesson covers how proteins are made, including the role of RNA polymerase, messenger RNA, transfer RNA, ribosomes and the role of start and stop codons. The lesson progresses into the roles of the DNA template (antisense) strand in transcription, codons on messenger RNA and anticodons on transfer RNA. Fully resourced with video’s and practise exam questions.

This lesson starts with a review of the definition of homeostasis and recall of the role of the kidney. The main body of the lesson explores the three roles of the skin, including it’s role in temperature regulation. Students are given a diagram of the skin and are asked to label it, extension questions within the PPT slide are there to prompt ideas about how the involuntary nervous system controls the sweat glands and hairs. The lesson looks at physiological responses to temperature and the role of the thermoregulatory centre in the brain. Finishing off with higher tier components of vasodilation and vasoconstriction. The plenary concludes with a multiple choice quiz. A CIE specific assessment and marks scheme is also included.

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 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 covers interpretion and constructing genetic diagrams to predict the results of dihybrid crosses that involve autosomal linkage. Some material has been adapted from other TES contributors and I have included additional material to support.

This lesson covers the when and why DNA needs to replicate, and how DNA replicates. The lesson then looks at understanding the roles of DNA polymerase and ligase. Fully resourced.

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

This lesson starts with a quick review of chromosome structure and then the details of the structure of nucleotides. The lesson then moves onto base pairing, hydrogen bonding and phosphodiester bonding. Fully resourced with a lot of extra consolidation activities.

This lesson starts by recalling the definition of osmosis and the structure of the cell membrane. The lesson then covers passive transport, active transport, endocytosis and exocytosis and explains the use of carrier and channel proteins in cell membranes.

In this lesson students recall genetic terminology from KS4 and use genetic diagrams to predict and explain the results of monohybrid crosses involving: dominance, multiple alleles and co-dominance. Some the presentation is copied and changed from other teachers, and comes fully supplied with lots of crossing practise.

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.

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 starts be recalling differences between hormonal and nervous control then revisits KS4 learning on the neurone and the CNS. Sensory, relay and motor neurones are covered, including the finer ultrastructures. All resources included.

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.
