Learning Intentions Students will be able to: • describe the role of the digestive system; • identify the organs in the human digestive system and describe their function; • explain the difference between mechanical and chemical digestion and identify where each occurs in the digestive system • describe the role of enzymes in the breakdown of food in the digestive system; • identify the question for investigation; • make predictions based on scientific knowledge; • identify variables to be changed, measured and controlled in an investigation; • record and represent observations and data; • identify patterns and trends from observations and data; • use patterns and trends observed to draw a conclusion; • explain how modifications to their investigation could improve the quality of their data.
