This lesson introduces monomers, polymers, condensation and hydrolysis reactions and chemical bonds to prepare students for the rest of topic 1 (biological molecules). The PowerPoint and accompanying worksheet cover point 1.1 of the AQA A-level Biology course, and as this is likely to be the very first lesson that the students encounter, the range of engaging tasks have been specifically designed to increase the likelihood of the key points and fundamentals being retained.

Monomers were previously met at GCSE and so the beginning of the lesson focuses on the recall of the meaning of this key term before the first in a series of quiz rounds is used to introduce nucleotides, amino acids and monosaccharides as a few of the examples that will be met in this topic. Dipeptides and disaccharides are introduced as structures containing 2 amino acids or sugars respectively and this is used to initiate a discussion about how monomers need to be linked together even more times to make the larger chains known as polymers. At this point in the lesson, the students are given the definition of a condensation reaction and then challenged to identify where the molecule of water is eliminated from when two molecules of glucose join. A series of important prefixes and suffixes are then provided and students use these to predict the name of the reaction which has the opposite effect to a condensation reaction - a hydrolysis reaction.

Links to upcoming lessons are made throughout the PowerPoint to encourage students to begin to recognise the importance of making connections between topics.

Topic 1: Biological molecules (AQA A-level Biology)

The biological molecules topic is incredibly important, not just because it is found at the start of the course, but also because of its detailed content which must be well understood to promote success with the other 7 AQA A-level Biology topics. Many hours of intricate planning has gone into the design of all of the 20 lessons that are included in this bundle to ensure that the content is covered in detail, understanding is constantly checked and misconceptions addressed and that engagement is high. This is achieved through the wide variety of tasks in the PowerPoints and accompanying worksheets which include exam-style questions with clear answers, discussion points, differentiated tasks and quick quiz competitions. The following specification points are covered by the lessons within this bundle: * Monomers and polymers * Condensation and hydrolysis reactions * Common monosaccharides * Maltose, sucrose and lactose * The structure and functions of glycogen, starch and cellulose * Biochemical tests using Benedict's solution for reducing sugars and non-reducing sugars and iodine/potassium iodide for starch * The structure and properties of triglycerides and phospholipids * The emulsion test for lipids * The structure of amino acids * The formation of dipeptides and polypeptides * The levels of protein structure * The biuret test for proteins * Enzymes act as biological catalysts * The induced-fit model of enzyme action * The properties of an enzyme * The effect of temperature on the rate of an enzyme-controlled reaction * The effect of enzyme and substrate concentration on the rate of an enzyme-controlled reaction * The effect of competitive and non-competitive inhibitors on the rate of an enzyme-controlled reaction * The structure of DNA and RNA * The semi-conservative replication of DNA * ATP as the universal energy currency * The properties of water and its importance in Biology * Inorganic ions Due to the detail of each of these lessons, it is estimated that it will take in excess of 2 months of allocated teaching time to cover the content.

Useful info on the power points but backgrounds are very bold however some teachers might like the vibrancy and the potential to engage students visually this way

It wasnt what i thought it would be. As a power point it looks great but as a resource without the commentary and delivery its not as useful
