Natural Science - Term 2 - Week 5

In Natural Science, vocabulary is crucial for understanding concepts. This week, we will focus on terms such as 'ecosystem', 'photosynthesis', 'habitat', and 'adaptation'. Understanding these words will help you communicate scientific ideas effectively. We will discuss each term, its definition, and its relevance in the study of natural science.

Let's look at the process of photosynthesis as an example of how we can apply our vocabulary. Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Here, 'photosynthesis' is the key term, and understanding it involves knowing the roles of sunlight, chlorophyll, and the reactants involved. We will break down this process step by step to ensure clarity.

Now, let's work together on a vocabulary matching exercise. I will provide you with definitions, and you will match them to the correct terms. For example, if I say 'the place where an organism lives', you would match it to 'habitat'. This exercise will help reinforce your understanding of these key terms in context.

For your independent practice, you will create a mini-poster that illustrates one of the key concepts we discussed this week. Choose a term such as 'ecosystem' or 'adaptation' and include a definition, a diagram, and examples. This will allow you to apply what you've learned creatively. After completing your poster, be prepared to present it to the class.

• Respiration
• Photosynthesis
• Transpiration
• Digestion

Answer: Photosynthesis

Photosynthesis is the process where plants convert sunlight into chemical energy.

• Niche
• Ecosystem
• Habitat
• Community

Answer: Niche

A niche refers to the specific role or function of an organism within its ecosystem.

Answer: A habitat is the natural environment where an organism lives.

Understanding habitats helps us learn about the needs of different organisms.

• A plant growing towards the sun
• A fish swimming
• A bird migrating
• All of the above

Answer: All of the above

Adaptations can be behavioral, physiological, or structural, and all these examples illustrate adaptations.

Answer: Carbon dioxide

Plants absorb carbon dioxide from the atmosphere to produce glucose.

• Producers
• Consumers
• Decomposers
• Pollutants

Answer: Pollutants

Pollutants are harmful substances and not a natural component of an ecosystem.

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

Ecosystems include both biotic and abiotic factors that affect the organisms living there.
