A2 Biology
Produced by Nelson Thornes, these materials help students to reinforce their understanding of key A2 level biology topics. Designed for the AQA specifications, they can also be applied to other courses.
Materials contain teacher notes and student activity sheets. They cover topics that include:
• Carbon fixation
• Protein synthesis
• Gene therapy
• Selection and speciation
• Ecological niche
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
Carbon Fixation in C4 and CAM Plants
From Nelson Thornes, these activities help students to reinforce their understand of photosynthesis. In particular the mechanisms for carbon fixation by comparing the Calvin cycle with alternative ways of fixing carbon dioxide. Students discuss the advantages of each pathway and understand the conditions that make them beneficial. These…
Gene Therapy Using Artificial Chromosomes
From Nelson Thornes, these activities encourage students to consider the processes involved in gene therapy. Students are presented with an article about a method of gene therapy that uses artificial chromosomes before answering a set of questions comparing this method to more traditional techniques and the possible advantages of…
Investigating the Concept of a Niche
From Nelson Thornes, these activities encourage students to consider their understanding of an ecological niche. Students investigate the idea of a niche and look at the concepts of a fundamental niche and a realised niche. They are also asked to use information on a particular species’ niche, to predict where we may find this…
Neural Toxins and Poisons
From Nelson Thornes, these activities encourage students to investigate nervous transmission by considering the effects of various toxins and poisons on the nervous system. These include botulinum toxin (Clostridium botulinum), tetanospasmin (Clostridium tetani), tetradotoxin (pufferfish) and atropine (Deadly Nightshade). In…
Organic Farming Versus Intensive Farming
From Nelson Thornes, these activities encourage students to analyse and discuss the advantages and disadvantages of organic farming compared with intensive farming. Students are asked to use the information in an article along with their own knowledge to decide whether there is a global future for organic farming, or whether…
Protein Synthesis - Prokaryotes and Eukaryotes
From Nelson Thornes, these activities encourage students to examine the process of protein synthesis. They look at the differences in this process in prokaryotic and eukaryotic organisms. Students are asked to consider the detailed mechanisms and assess the benefits of the different methods. These biology resources are aimed at…
