Natural Science - Term 1 - Week 5

In Natural Science, vocabulary is crucial for understanding complex concepts and processes. This week, we will focus on key terms such as 'ecosystem', 'photosynthesis', 'cellular respiration', and 'biodiversity'. Understanding these terms will help you articulate scientific ideas and engage in discussions about the natural world.

Let's take the term 'photosynthesis'. Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll. In a sentence: 'During photosynthesis, plants convert carbon dioxide and water into glucose and oxygen using sunlight.' This example shows how the term is used in a scientific context.

Now, let's work together on a vocabulary matching exercise. I will provide you with a list of terms and their definitions. Your task is to match each term with the correct definition. For example, match 'ecosystem' with 'a community of living organisms and their environment interacting as a system'. This will help reinforce your understanding of each term.

For your independent practice, choose five vocabulary words from our list and write a short paragraph for each, explaining their significance in Natural Science. Use them in context, just like we practiced. This will help you solidify your understanding and ability to use these terms effectively.

• Respiration
• Photosynthesis
• Transpiration
• Decomposition

Answer: Photosynthesis

Photosynthesis is the process where plants use sunlight to convert carbon dioxide and water into glucose.

• Ecosystem
• Biodiversity
• Population
• Community

Answer: Biodiversity

Biodiversity refers to the variety of living organisms in a specific area, including different species and ecosystems.

• A group of similar organisms
• A community of living organisms and their environment
• A single organism
• A type of plant

Answer: A community of living organisms and their environment

An ecosystem includes all living things in a particular area, interacting with each other and their physical environment.

Answer: Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

This process is essential for providing energy to cells for various functions.

Answer: Photosynthesis is significant because it produces oxygen and organic compounds that are essential for life on Earth.

It forms the base of the food chain and supports life by providing energy.

• Producers
• Consumers
• Decomposers
• Weather

Answer: Weather

While weather affects ecosystems, it is not a living component like producers, consumers, or decomposers.

• They produce energy
