Includes 72 marks of practice exam questions (with answers) on… B5 - Homeostasis & Response B6 - Inheritance, Variation & Evolution B7 - Ecology Aimed at Foundation students, but could also be used with Higher.

A full 60 minute lesson on Quantitative Investigations of Diversity, covering the following LOs… Explain how random samples can be obtained. Explain what standard deviation is and how it is calculated. Represent raw and processed data clearly using tables and graphs. Interpret data in terms of means and the overlap of standard deviation bars. Apply knowledge of, to draw and explain conclusions. Evaluate the quality of results and reliability of conclusions. Lesson includes starter task, recall questions (and answers), and also practice exam questions (and mark scheme).

A full 60 minute lesson on Mutations, covering the following LOs… Describe the different types of gene (point) mutations. Explain how deletion, insertion and substitution of bases result in different amino acid sequences in polypeptides. Explain why some mutations do not result in a changed amino acid sequence. Describe what chromosome mutations are. Lesson includes starter task, summary questions (and answers), plenary, and also a homelearning task with practice exam questions (and mark scheme).

A full 60 minute lesson on The Effects of Selection, covering the following LOs… Describe what selection is. Describe the environmental factors which exert selection pressure. Explain what stabilising and directional selection are. Lesson includes starter task, summary questions (and answers), plenary, and also a homelearning task with practice exam questions (and mark scheme).

A full 60 minute lesson on DNA, Genes and Chromosomes, covering the following LOs… Explain what is meant by the terms chromosome, gene and allele. Compare and contrast DNA in eukaryotes with that in prokaryotes, mitochondria and chloroplasts. Explain how the DNA base sequence is able to code for the primary structure of a polypeptide. Explain the terms degenerate, universal and non-overlapping. Explain why much of eukaryotic DNA can be considered as non-coding. Explain what is meant by an intron and an exon. Lesson includes starter task, summary questions (and answers), and practice exam questions (and mark scheme).

A full lesson on Transcription (Protein Synthesis), covering the following LOs… Explain what the terms genome and proteome mean. Describe the structure of mRNA and how it is related to its function (link to biological molecules topic). Explain the process of transcription in prokaryotes. Explain the process of transcription and splicing in eukaryotes, linking this to knowledge of introns. Interpret data from experimental work investigating the role of nucleic acids. Lesson includes starter task and summary questions (and answers).

A full 60 minute lesson on Biodiversity (within a community), covering the following LOs… Explain what is meant by the terms biodiversity, species richness and index of diversity. Calculate the index of diversity when supplied with relevant information. Interpret information and draw conclusions from the index of diversity for different habitats. Explain how farming techniques impact on biodiversity and the reason why these techniques are used. Evaluate conservation techniques and why these must be balanced with farming. Lesson includes starter task, recall questions (and answers), and also practice exam questions (and mark scheme).
