Fully resourced, high quality, easy to follow KS3 Science lesson. The lesson is designed to follow a 5 part lesson structure including; do now, starter, activate, demonstrate and plenary. The aim of the lesson is for students to understand the different ways that a plant can reproduce and the advantages and disadvantages of each method. Students will learn to: Recall how the definitions of sexual and asexual reproduction. Identify examples of sexual and asexual reproduction. Compare sexual and asexual reproduction, producing a written paragraph to be self/peer assessed at the end of the lesson. Understanding of the core questions linked to the lesson outcomes and objectives are reviewed during the plenary, to assess whole class progress. The lesson is chunked into sections to provide scaffolding support for students. The lesson is designed to be engaging for all and provides time for review to address any misconceptions throughout. The demonstrate task can be printed or provided on an online platform such as OneNote. SUPPORT/CHALLENGE Both support and extension activities are included throughout.

A bundle of lessons for Topic 4a SNAB Biodiversity L1 Biodiversity L2 Measuring Biodiversity L3 Niche and adaptations L4 Natural Selection L5 Hardy Weinburg L6 Standard deviation L7 Speciation The lessons include a student copy which can be used as a handout or as interactive notes on onenote. Each lesson links to closely to the specification and this is highlighted on the introduction page for each lesson. The keywords for the lesson are also identified - I recommend students developing a keyword bank and consistently adding definitions to this. Each lesson includes a Do Now… activity at the start of the lesson, this is used as retrieval practice and to identify any misconceptions from the previous lesson.

This is the second lesson from the SNAB Topic 4: Biodiversity and natural resources. It includes an introduction to heterozygosity index and simpsons index of diversity. There are practice questions included for students to complete. This links to the specification: ii) Know how biodiversity can be measured within a habitat using species richness and within a species using genetic diversity by calculating the heterozygosity index (H): iii) Understand how biodiversity can be compared in different habitats using a formula to calculate an index of diversity (D):

This is the first lesson from SNAB Topic 4: Biodiversity and natural resources. It includes a student copy of the lesson which can be used alongside the teacher copy as a handout or onenote resource. The lesson includes a student led research activity in which students use the red list to identify critically endangered animals and identify the factors responsible for the decrease in biodiversity. The lesson links to the specification: 4.1 Know that over time the variety of life has become extensive but is now being threatened by human activity. 4.2 i) Understand the terms biodiversity and endemism.
