Description
The module combines CLIL methodology and IBSE teaching. It focuses on Enzymes, and consists of two parts, one dedicated to theory and one to a laboratory experiment on the influence of temperature and pH on Enzymes activity.
Aims
1. To understand the role played by enzymes in biochemical reactions; 2. to encourage attitude of scientific inquiry and team work; 3. to increase digital skills. This teaching unit focuses on the study of the properties of enzymes in order to investigate the relationship between enviromental parameters (pH, T) and enzyme activity.
Outcomes
  • Define to give a definition of enzymes and their key aspects
  • Explain to describe the way enzymes function at molecular level, using appropriate language;
  • Illustrate to describe the interaction between enzymes and specific environmental factors in the human body;
  • Construct to produce a visual representation of the learnt content in the form of a concept map;
  • Question to formulate questions
  • Hypothesise to construct a hypothesis
  • Show awareness of to be aware of one's own choices
  • Find to find the relationship between the enzyme activity and the PH trend
  • Find to find the relationship between the enzyme activity and the PH trend
  • Explain to explain the effects of temperature and pH on catalase enzyme activity.
