Mitosis and mitotic index GCSE, iGCSE, MYP

Revision mat covering the SL topics in A1.1.1 Water 2025 spec (designed to be printed A3)

Pedigree Chart Workbook Autosomal/X linked and recessive/dominant pedigree charts Extension questions about codominance and incomplete dominance Some pedigree charts taken from ‘Biology For Life’.

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

SA:V and the relation to diffusion and exchange surfaces

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

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.
