This lesson provides a powerpoint style lesson plan for introducing Carbohydrates, Monosaccharides, disaccharides and polysaccharides and the practical for testing reducing sugars (Benedict's test).
It covers the following lesson objectives:
Objectives:
1) Describe how carbohydrates are constructed - pupils make simple drawings of mono - one; di - two; tri - three
2) Describe the structure of monosaccharides - spot the difference activity; drawing molecular arrangements; writing chemical formula for alpha and beta glucose
3) Describe how to carry out the Benedict’s test for reducing and non-reducing sugars - the theory for the test is simply explained with diagrams; the method for the test is explained; a summary check is given in the form of a table (answers included in the powerpoint) to see that pupils can understand the colour changes from the Benedict's test; further detailed practical instructions are provided for pupils to perform the semi-quantitative test for reducing sugars using Benedict's Solution. This is accompanied by practical questions and a table for the recording of results.
