Natural Science - Term 1 - Week 9

This week, we will review the major topics covered in Natural Science this term, including ecosystems, the water cycle, and the properties of materials. Understanding these concepts is crucial as they form the foundation for more advanced topics in the future. We will focus on the vocabulary associated with each topic, ensuring that you can use these terms accurately in your discussions and written work.

Consider a simple food chain: grass → rabbit → fox. In this example, grass is the producer, rabbits are primary consumers, and foxes are secondary consumers. Each organism plays a vital role in the ecosystem. If one part of this chain is affected, it can impact the entire ecosystem. For instance, if the rabbit population decreases due to disease, the foxes may struggle to find food, leading to a decline in their population as well.

In pairs, match the following vocabulary words with their correct definitions: 1) Ecosystem, 2) Photosynthesis, 3) Habitat, 4) Biome. After matching, discuss with your partner why each definition fits its corresponding word. This activity will help reinforce your understanding of these key terms and their significance in Natural Science.

Write a short paragraph reflecting on what you found easy and what you found challenging this term in Natural Science. Consider the topics we covered and how they relate to the real world. Additionally, create a simple diagram illustrating the water cycle, labeling each part (evaporation, condensation, precipitation, collection). This task will help you synthesize your learning and apply it creatively.

• Water
• Soil
• Sunlight
• Carbon Dioxide

Answer: Sunlight

Photosynthesis relies on sunlight to convert carbon dioxide and water into glucose and oxygen.

• Grass
• Rabbit
• Fox
• Eagle

Answer: Rabbit

Primary consumers are herbivores that eat producers, such as rabbits eating grass.

• Condensation
• Evaporation
• Precipitation
• Transpiration

Answer: Evaporation

Evaporation is the process where water changes from liquid to gas, entering the atmosphere.

• Ecosystem
• Habitat
• Biome
• Community

Answer: Habitat

A habitat is the specific environment where an organism lives and thrives.

Answer: An ecosystem is a community of living organisms interacting with their physical environment.

This definition captures the essence of how organisms and their environment work together.

Answer: Decomposers break down dead organic matter, recycling nutrients back into the soil.

Decomposers are essential for nutrient cycling, helping to maintain ecosystem health.

Answer: Climate change and pollution.

Both climate change and pollution can disrupt the balance of ecosystems and harm living organisms.
