Layout of the lesson
•What is colorimetry and what does light absorbance tell us about the concentration of a substance
•Recap on how light intensity links to starch in plants and how this links into the colorimetry investigation
•Students write their own risk assessment
•Loose method on how to prepare a standard solution of starch and dilutions with a table to scaffold to students quantities of water and starch that need mixing to achieve certain dilutions
•The importance of using the right wavelength and filter in colorimetry and how to identify the most suitable filter for this investigation
•Loose method and table for students to conduct 3 trials of each concentration of starch using colorimetry
• Guide slide on data analysis for how to draw a calibration curve accurately and use it to identify the concentrations of the unknown solutions + prompt to explain how results link to light intensity and photosynthesis
•Evaluation guides with prompts to support students in writing and in-depth evaluation. It is wise to encourage students to think about their own experiences during the practical for where issues may have arisen and how these could be resolved in the future
