Natural Science - Term 3 - Week 10

Application tasks are designed to help you use the knowledge and skills you've learned in Natural Science. This week, we will focus on applying scientific concepts through various guided tasks. You will practice using key vocabulary, engage in activities that reinforce your understanding, and reflect on your learning experiences. This process will help you solidify your knowledge and prepare you for future assessments.

Let's consider the term 'ecosystem.' An ecosystem includes all living organisms in a particular area, interacting with each other and their environment. For example, in a forest ecosystem, you might find trees, animals, insects, and microorganisms all working together. When we apply this term, we can describe how changes in one part of the ecosystem, like deforestation, can affect the entire system. This example shows how understanding vocabulary helps us explain real-world situations.

In pairs, create a list of components found in a specific ecosystem of your choice (e.g., desert, rainforest, ocean). For each component, write a brief description of its role within the ecosystem. After 10 minutes, we will share our lists with the class. This task will help you practice using vocabulary related to ecosystems and understand their interconnections.

Individually, write a short paragraph reflecting on what you found easy and what you found challenging during today's lesson. Additionally, choose one scientific concept we discussed and explain how it applies to a real-world situation. This task will encourage you to think critically about your learning and apply your knowledge in a meaningful way.

• A group of similar species
• All living organisms in a specific area interacting with their environment
• A type of climate
• A food chain

Answer: All living organisms in a specific area interacting with their environment

An ecosystem includes all living organisms and their interactions within a specific environment.

• Plants
• Animals
• Weather
• Gravity

Answer: Gravity

Gravity is a physical force, not a biological component of an ecosystem.

Answer: Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Producers are essential as they provide energy for consumers in the ecosystem.

• The ecosystem remains unchanged
• The ecosystem may collapse
• Only that species becomes extinct
• More species will thrive

Answer: The ecosystem may collapse

Removing a key species can disrupt the balance of the ecosystem, leading to potential collapse.

Answer: Biodiversity refers to the variety of life in an ecosystem. It is important because it enhances ecosystem resilience and productivity.

Higher biodiversity contributes to the stability and health of ecosystems.

• A series of organisms each dependent on the next as a source of food
• A list of all species in an ecosystem
• A diagram of an ecosystem
• A type of habitat

Answer: A series of organisms each dependent on the next as a source of food

A food chain illustrates the flow of energy from one organism to another.
