Created for IBDP students, also suitable for A-Level. Discusses: universal nature of DNA Universal common ancestor RNA/DNA structure Polymers/monomers Nucleotide structure (DNA and RNA) Ribose and deoxyribose structure Pentose sugars and numbering carbons Nitrogenous bases and complementary base pairing Phosphodiester bonds and the sugar phosphate backbone Anti-parallel strands Double helix Exam questions (mix of IB and A-Level)

Part of a MYP5/Year 11 skills unit at the end of the year (post exams) The purpose of the lesson (and later lessons) is to ask students to think critically about scientific content online. Includes discussion about mis/disinformation, reliability, why people post disinformation etc. This is part of a project in later lessons.

Science and Language/Literature IDU interdisciplinary unit MYP eAssessment prep unit for 2025 May Exams. All resources are my own and I wrote the exam questions, but exam rubric, exemplars etc are from IB

Magnification (MIA and total magnification as well as scale bars) Unit conversions practical instructions to make a temporary mount of onion or cheek cells This lesson was made for the purpose of a ‘IB DP Prep unit’ at the end of term for MYP5/Year 11

Use as a starting point because this was covered very quickly with my class. Has lessons, some handouts, my handdrawn processes, some exam questions from a variety of sources etc

Designed to be used as a ‘roundup’ lesson for biotechnology topic. Covers a practice Criterion D - my class did it as a pair activity, but can be assessed.

This is an introduction to Photosynthesis (lesson 1) for IB DP Biology Students, covering the photosynthesis equation, different pigments, and chromatography

Insulin activation of Tyrosine Kinase Receptors Quorum Sensing Signaling at the synapse by Neurotransmitters GPCR Activation by Epinephrine/Adrenaline Lactose production by the Lac Operon Intraxellular signaling by Oestradiol to influence gene expression I printed this on different coloured paper and cut them out so students had to arrange the processes into the correct order, then answer the questions with a partner

New 2025 Specification Unit D3.1 Angiosperm Reproduction Lessons included: Plant features, sexual reproduction and cross-pollination Dispersal and Germination Flower Dissection Fruit Ripening Exam Skills and Longer Response Lesson (based on whole curriculum)

IB Bio Standard Level Lung Volumes and Spirometer traces with how to analyse Neural control of ventilation rate (medulla, respiratory centre etc)

Designed for MYP Active Transport and the idea of ‘concentration gradients’

Diffusion - designed for MYP students Includes factors affecting diffusion (and a research task for students, with examples of work)

SA:V and the relation to diffusion and exchange surfaces

Impacts of Lactose and Oestrogen on the expression of associated genes (Lac Operon in bacteria)

Epigenetic Modification of Nucleosomes (phosphorylation, methylation, acetylation) With exam questions

Iodine test for starch, emulsion test for lipids, benedict’s test for sugars, biuret test for proteins Space for students to note the colour change, hazards, a brief method, and colour a test tube based on the results This was designed as an overview/recap homework for Y11 students who were taught this in Y10

Epigenetic modification of DNA and histones (acetylation, methylation, phosphorylation), genome/proteome/tramscriptome, inheritance of genetic tags, effect of air pollution on gene expression, monozygotic twin studies With exam questions and links to further reading

Designed for IB HL Students Gene Expression Regulation of Transcription (Transcription Factors) mRNA Degradation (regulation of translation) Epigenetics Intro Epigenetic modification of chromatin - acetylation, phosphorylation, methylation With exam questions and answers

Recombinants - designed for IB HL Biology Students Includes exam questions (from IB and self-created)
