PowerPoint on Genetics and Inheritance, covering: What are alleles? What is recessive and dominant? What is homozygous and heterozygous? What is genotype and phenotype? How can Punnett Squares be used to show genetic crosses and calculate possible offspring?

PowerPoint presentation introducing the topic of infectious disease. Objectives are to identify the difference between infectious and non-infectious disease and to identify a range of pathogens, including prions, viruses, bacteria, fungi, protists and parasites. Includes definitions of health and disease. Written for QCAA Biology syllabus, but suitable for an introduction to the topic for most courses.

Genetics Problems PowerPoint 2 Suitable for use as revision tool at end of genetics topic. Includes: Pedigree Charts Monohybrid and dihybrid inheritance ABO blood types Co-dominance Gene linkage and Cross-Over Frequencies Genetic Fingerprinting Aimed at senior students (Years 10-12)

Powerpoint looking at what limits cell size, considering surface area to volume ratio and diffusion rate. Introduces unicellular vs. multicellular organisms, and looks at the need for transport systems in multicellular organisms to supply cells with resources.

Powerpoint for high school biology students, covering passive (osmosis, diffusion, facilitated diffusion) and active transport (endocytosis, phagocytosis, pinocytosis, exocytosis).

Punnett Squares PPT including worked questions with answers. Includes monohybrid, co-dominance, incomplete dominance and dihybrid examples. Objectives are to learn to: Create a Punnett square to represent a genetic cross. Predict frequencies of genotypes and phenotypes using Punnett squares. Written for senior biology students and teachers.

Simple worksheet with answers. Students match genetics keywords to definitions (I print out sheet and get them to colour, or they can work online and drag keywords to match definitions.) Keywords included: DNA, Gene, Translation, Chromosome, Phenotype, Allele, Nucleotide, Homozygous, Transcription, Autosome, Recessive, Sex chromosome, Sex-linked genes, Heterozygous, Chromatid, Dominant, Chromatin, Centromere, Karyotype

Student sheet for osmosis in potato experiment, testing the effect of different salt solutions on rate of osmosis.

PowerPoint introducing the topic of homeostasis, including stimulus-response model and negative feedback. Written to support new QCAA syllabus, but suitable for any senior course as an introduction to the topic.

PowerPoint presentation, providing an introduction to Marzano and Kendall’s educational taxonomy.

4 pages (A3) graphic organiser for student revision of cells topic

PowerPoint on animal cell structure and function of organelles. Includes links to further resources and quizzes online. Organelles covered include: nucleus, nucleolus, endoplasmic reticulum (RER and SER), centrosome, centriole, Golgi apparatus, cytoskeleton, mitochondria, vesicles (inlcuding lysosomes and peroxisomes), cell membrane and cytoplasm.

Worksheet with questions clearly organised in ascending order based on Bloom's Taxonomy. Answer sheets provided. Considers organelle structures and functions, including nucleus, RER, SER, lysosomes, Golgi apparatus, cell membrane and centrioles. Higher level questions suitable for extension.

This includes a series of activities (with answers)for senior biologists to consolidate learning of cell structure and function, including: • Crossword • Cryptograms • Wordsearch • Dominoes The keywords covered in these activities are: Cell membrane, Nucleus, Nucleolus, Cytoplasm, Cytoskeleton, Mitochondria, Golgi Apparatus, Rough Endoplasmic Reticulum (RER), Smooth Endoplasmic Reticulum (SER), Lysosome, Cell wall, Centriole, Nuclear pore, Chloroplast, Vacuole

PowerPoint introducing genetics: What is basic inheritance? Who was Mendel? What are pure breeding and hybrid organisms? What are dominant and recessive traits? What patterns of inheritance are seen with simple monohybrid crosses? Core content with learning objectives, key questions and links to further online resources including lessons.
