Natural Science - Term 2 - Week 7

This week, we will focus on revisiting the core concepts we have studied this term, including ecosystems, the water cycle, and the properties of matter. Understanding these concepts is crucial as they form the foundation for more advanced topics in Natural Science. We will also discuss the importance of scientific vocabulary in accurately describing these concepts.

Let's take a closer look at the water cycle. The water cycle consists of several stages: evaporation, condensation, precipitation, and collection. For instance, when the sun heats water in rivers and lakes, it evaporates into the atmosphere. This water vapor then cools and condenses to form clouds. Eventually, the water falls back to the ground as precipitation. Understanding this cycle helps us appreciate the importance of water in our environment.

In pairs, students will receive a list of key vocabulary words related to ecosystems and the water cycle. They will match each word with its correct definition. For example, students will match 'evaporation' with 'the process of turning from liquid into vapor.' This activity will help reinforce their understanding of the terms and their relevance in Natural Science.

Students will create a concept map that illustrates the relationships between the key concepts learned this term. They should include at least five concepts and show how they connect to one another. For example, they might connect 'ecosystem' to 'habitat' and 'biodiversity.' This task encourages students to synthesize their knowledge and visualize how different concepts are interrelated.

• Condensation
• Evaporation
• Precipitation
• Collection

Answer: Evaporation

Evaporation is the process where water changes from a liquid to a gas due to heat.

• Evaporation
• Transpiration
• Photosynthesis
• Precipitation

Answer: Photosynthesis

Photosynthesis is a process used by plants to convert light energy into chemical energy, not a stage of the water cycle.

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

An ecosystem includes all the living things in a particular area, along with the non-living components that interact with them.

• The process of water falling as rain
• The process of water vapor cooling and forming droplets
• The process of water turning into vapor
• The collection of water in rivers

Answer: The process of water vapor cooling and forming droplets

Condensation occurs when water vapor cools and changes back into liquid water, forming clouds.

Answer: Mass and volume.

Mass is the amount of matter in an object, while volume is the amount of space that matter occupies.

• Biodiversity
• Population
• Community
• Habitat

Answer: Biodiversity

Biodiversity refers to the variety of living organisms in a given area, including different species and genetic variations.

Answer: Precipitation is any form of water that falls from the atmosphere to the Earth's surface, such as rain, snow, or hail.
