Natural Science - Term 1 - Week 5

In Natural Science, vocabulary is crucial for understanding concepts and communicating ideas. This week, we will focus on key terms such as 'ecosystem', 'photosynthesis', 'habitat', and 'biodiversity'. Understanding these terms will help you grasp the relationships between living organisms and their environments. We will explore each term through definitions, examples, and their significance in the study of science.

Let's take the term 'ecosystem'. An ecosystem includes all the living organisms in a particular area, along with the non-living components like water and soil. For instance, a forest is an ecosystem where trees, animals, and microorganisms interact with each other and their environment. By using this term in a sentence: 'The forest ecosystem is rich in biodiversity, supporting various species of plants and animals.' This illustrates how vocabulary can be applied in 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, if I say 'photosynthesis', you should match it with 'the process by which green plants use sunlight to make food'. After completing the matching, we will discuss the meanings and importance of each term as a class.

For your independent practice, create a short paragraph using at least three of the vocabulary words we discussed today. Ensure that you use each word correctly in context. After writing your paragraph, share it with a partner and discuss how you used the vocabulary. This exercise will help reinforce your understanding and ability to use scientific terms effectively.

• A type of plant
• A community of living organisms and their environment
• A scientific experiment
• A method of studying

Answer: A community of living organisms and their environment

An ecosystem includes all living and non-living components interacting in a specific area.

• Respiration
• Photosynthesis
• Decomposition
• Transpiration

Answer: Photosynthesis

Photosynthesis is the process by which plants convert sunlight into energy to produce food.

• The variety of life in a particular habitat
• The number of species in extinction
• The study of living organisms
• The process of evolution

Answer: The variety of life in a particular habitat

Biodiversity refers to the different species and genetic variations within a specific ecosystem.

Answer: A habitat is the natural environment in which a species lives and grows.

Habitats provide the necessary conditions for organisms to survive, including food, shelter, and mates.

Answer: Photosynthesis is important because it produces oxygen and food for plants, which are essential for life on Earth.

Through photosynthesis, plants convert sunlight into energy, supporting the food chain and providing oxygen.

• Plants
• Animals
• Weather
• Technology

Answer: Technology

Technology is a human-made concept and does not belong to the natural components of an ecosystem.

• They produce food
• They consume plants
