Natural Science - Term 4 - Week 2

Creative application in Natural Science involves using knowledge and skills to solve problems or create new ideas. This week, we will explore how to apply scientific concepts creatively through various tasks. We will focus on key vocabulary that will help us articulate our thoughts and findings effectively.

Consider the concept of ecosystems. If we were to design a new ecosystem for a fictional planet, we would need to think about the types of organisms that would thrive there, their interactions, and the resources available. For example, if we choose a desert environment, we might include cacti, lizards, and insects, and discuss how they adapt to survive in such conditions.

In pairs, students will create a poster of a unique ecosystem. They should include at least three different organisms, their roles, and how they interact with each other. Use vocabulary such as 'producer', 'consumer', and 'decomposer' to describe these roles. After completing the poster, each pair will present their ecosystem to the class, explaining their choices and the interactions within their ecosystem.

Individually, students will write a short paragraph reflecting on the guided task. They should discuss what aspects of designing the ecosystem were easy and which were challenging. Additionally, they will apply their learning by proposing a new organism that could fit into their ecosystem, explaining its role and adaptations.

• An organism that eats other organisms
• An organism that makes its own food
• An organism that decomposes dead matter
• An organism that competes for resources

Answer: An organism that makes its own food

Producers, such as plants, create their own food through photosynthesis.

• Grass
• Frog
• Mushroom
• Sunlight

Answer: Frog

Frogs are consumers as they eat insects and other organisms.

Answer: A decomposer is an organism that breaks down dead organic material, returning nutrients to the soil.

Decomposers play a crucial role in recycling nutrients in ecosystems.

• To produce energy
• To consume plants
• To break down dead organisms
• To compete with producers

Answer: To break down dead organisms

Decomposers recycle nutrients by breaking down dead matter.

Answer: Desert plants often have thick, waxy skins to reduce water loss and deep roots to access underground water.

These adaptations help desert plants survive in arid conditions.

• A group of similar organisms
• A community of living organisms and their environment
• A single species in a habitat
• A collection of non-living things

Answer: A community of living organisms and their environment

An ecosystem includes both biotic (living) and abiotic (non-living) components.

• Mutualism
