Natural Science - Term 4 - Week 10

Independent practice is essential for reinforcing what you've learned in Natural Science. This week, we will focus on applying key concepts and vocabulary through a series of guided tasks. You will work on your own to solve problems, answer questions, and reflect on your learning process. This will help you become more confident in your understanding of the material.

Let's consider the process of photosynthesis. In this example, we will identify the key components involved. Photosynthesis occurs in plants, where they use sunlight, carbon dioxide, and water to produce glucose and oxygen. If we were to create a diagram, we would label the sun, leaves, and the chemical equation: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2. This visual representation helps us understand the process better.

Now, let's work on a guided task together. I want you to list the components of an ecosystem. Think about the living (biotic) and non-living (abiotic) factors. For example, biotic factors include plants and animals, while abiotic factors include water, soil, and sunlight. Write down at least five examples of each and be prepared to share your findings with the class.

For your independent practice, you will create a mini-project about an ecosystem of your choice. Choose an ecosystem such as a rainforest, desert, or ocean. Include the following: a description of the ecosystem, a list of biotic and abiotic factors, and a diagram illustrating the relationships between these components. Be creative and use your knowledge from this term to make your project informative and visually appealing.

• Respiration
• Photosynthesis
• Transpiration
• Fermentation

Answer: Photosynthesis

Photosynthesis is the process by which plants convert sunlight into chemical energy, producing glucose and oxygen.

• Water
• Soil
• Plants
• Sunlight

Answer: Plants

Biotic factors are living components of an ecosystem, such as plants and animals.

• Biotic factors
• Abiotic factors
• Producers
• Consumers

Answer: Abiotic factors

Abiotic factors include non-living elements like water, soil, and sunlight.

Answer: Water and sunlight

Water and sunlight are essential abiotic factors that support life in ecosystems.

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

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

• Glucose
• Oxygen
• Carbon Dioxide
• Nitrogen

Answer: Nitrogen

Nitrogen is not involved in the photosynthesis process; the main components are sunlight, carbon dioxide, and water.

• Oxygen
• Carbon Dioxide
• Glucose
• Water

Answer: Glucose

The main product of photosynthesis is glucose, which plants use for energy.
