Life Processes in Animals

Warm Up: Brainstorming Activity

Think-pair-share:

• What foods do you think different animals eat?

• Can all animals eat same type of food?

• How do you think they get it and use it for energy?

Learning Objectives

At the end of the lesson you will be able to:

• Describe the process of nutrition and respiration in animals.

• Compare how different animals eat and breathe.

• Apply knowledge to real-life situations.

Nutrition in Animals

Animals can be herbivores, carnivores, or omnivores. They take in food, break it down, and absorb nutrients for growth and energy.

Respiration in Animals

Respiration is the process of taking in oxygen and releasing carbon dioxide. Animals may use lungs, gills, or skin to respire.

Group Activities: 5min

Groups 4-6: Respiration

Groups 1-3: Nutrition

Group 4: Draw the Human respiratory system and explain the process of cellular respiration.

Group 5: Compare breathing in amoeba, earthworm and frog with the mammals.

Group 6: Create a flow chart showing how Nutrition and Respiration are connected.

Group 1: Create a food chain poster.

Group 2: Compare digestive systems of two animals.

Group 3: Explain the journey of food in the human body.
