Healthy diet (Part 2)
This lesson looks at what factors affect our daily calorie intake and calculating energy requirements for different activities.
Unhealthy diet
This lesson describes the effects of a poor diet on the body. We will explore the impact of getting too much or too little of a particular nutrient. This lesson contains images of disease and malnutrition.
Energy release
This lesson looks at what the body needs energy for and how our bodies release the energy from our foods.
Carbohydrates
This lesson explores what we mean by carbohydrates and how to chemically test for the presence of these in foods.
Protein and Fats
This lesson explores what proteins and fats are and how to chemically test for the presence of these in foods.
Review point (Part 1)
This lesson reviews our learning of the topic so far.
The digestive system
This lesson looks at how our bodies are equipped to digest the food that we eat and why it is necessary. We are going to take a journey through the digestive system, looking at the role of each of the different organs.
Adaptations of the small intestine
This lesson takes a closer look at how the small intestine is adapted specifically for the absorption of different nutrients from our food.
Enzymes
This lesson describes the action of enzymes in the digestive system. We will observe a "model gut" experiment and evaluate this model.
Effect of temperature on enzymes
This lesson describes how a change in temperature affects the activity of enzymes.
Case study of Rebecca Lancefield
This lesson explores the life and work of revolutionary microbiologist Rebecca Lancefield and how she dedicated her 60-year scientific career to understanding Streptococcus, and other bacteria, which paved the way for modern antibiotics.
Review point (Part 2)
This lesson reviews the digestive system, adaptations of the small intestine, the role of enzymes in digestion and how temperature affects enzyme activity.
