Natural Science - Term 3 - Week 7

Core concepts in Natural Science include the understanding of ecosystems, the scientific method, and the properties of matter. This week, we will focus on how these concepts interconnect and their relevance in everyday life. For instance, understanding ecosystems helps us appreciate biodiversity and the importance of conservation efforts.

Let's consider a simple experiment: observing plant growth under different light conditions. The steps of the scientific method include asking a question (e.g., 'How does light affect plant growth?'), forming a hypothesis (e.g., 'Plants grow taller in natural light than in artificial light'), conducting the experiment, collecting data, and drawing conclusions. This example illustrates how the scientific method is applied in real-world scenarios.

In pairs, students will match key vocabulary words with their definitions. Words include 'ecosystem', 'hypothesis', 'variable', and 'biodiversity'. After matching, each pair will share their definitions with the class, ensuring everyone understands these essential terms. This activity reinforces vocabulary and encourages collaboration.

Students will design a simple experiment based on a question of their choice related to natural science. They will outline their hypothesis, the materials needed, and the steps they will take. After completing their plans, students will present their experiments to the class, fostering creativity and critical thinking.

• Forming a hypothesis
• Conducting an experiment
• Asking a question
• Analyzing data

Answer: Asking a question

The scientific method begins with a question that guides the research process.

• A group of similar organisms
• A community of living organisms and their environment
• A scientific experiment
• 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 environment.

Answer: A hypothesis is a testable prediction about the outcome of an experiment.

A hypothesis provides a basis for experimentation and helps guide the research process.

• The variety of life in a particular habitat
• The number of species in a laboratory
• The process of photosynthesis
• The study of rocks

Answer: The variety of life in a particular habitat

Biodiversity encompasses the different species and genetic variations within an ecosystem.

Answer: Light, water, soil quality, or temperature.

Various environmental factors can influence how well plants grow.

• Independent variable
• Dependent variable
• Control variable
• Constant variable

Answer: Constant variable

While independent, dependent, and control variables are essential components of an experiment, 'constant variable' is not a standard term used in scientific methodology.
