20-D1.2s

Performing and Recording: Students will  conduct investigations into relationships between and among observable variables and use a broad range of tools and techniques to gather and record data and information   • observe, through dissection or computer simulations, the digestive and respiratory systems of a representative mammal and identify the major structural components (PR-NS2)(PR-NS4)(PR-NS5)   •perform experiments, using qualitative tests, to detect the presence of carbohydrates, proteins and lipids (PR-NS2)(PR-NS3)(PR-NS4)(PR-NS5) (e.g.   •perform an experiment to investigate the influence of enzyme concentration, temperature or pH on the activity of enzymes such as pepsin and pancreatin (PR-NS2)(PR-NS3)(PR-NS4)(PR-NS5) ) ( e.g.   •perform an experiment to examine the mechanics of breathing, such as lung volume, breathing rate (PR-NS2)(PR-NS3)(PR-NS4)(PR-NS5))
