Natural Science - Term 4 - Week 7

Guided practice is a teaching method where students work through tasks with the support of the teacher. This week, we will focus on reinforcing our understanding of scientific concepts, including the scientific method, ecosystems, and the properties of matter. We will engage in short tasks that will help us practice key vocabulary and apply our learning in a structured way.

Let's consider a simple experiment: 'Does the amount of sunlight affect plant growth?' First, we identify our question. Next, we form a hypothesis: 'If a plant receives more sunlight, then it will grow taller.' We then outline our method, which includes measuring plant height over a week with varying sunlight exposure. Finally, we analyze our results and draw conclusions based on our observations.

Match the following scientific terms with their correct definitions. Terms include: 'ecosystem', 'photosynthesis', 'matter', and 'hypothesis'. This task will help reinforce your understanding of these key concepts. After completing the matching, we will discuss the definitions as a class.

Now it's your turn! Design a simple experiment based on a question of your choice. Write down your hypothesis, the materials you will need, and the steps you will take to conduct the experiment. Be prepared to share your experiment with the class and explain the scientific method you used.

• Forming a hypothesis
• Conducting an experiment
• Identifying a question
• Analyzing results

Answer: Identifying a question

The first step is to identify a question that you want to investigate.

• Respiration
• Photosynthesis
• Transpiration
• Decomposition

Answer: Photosynthesis

Photosynthesis is the process by which plants convert sunlight into chemical energy.

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

An ecosystem includes both biotic (living) and abiotic (non-living) components.

• A proven fact
• An educated guess
• A conclusion
• A type of experiment

Answer: An educated guess

A hypothesis is a proposed explanation for a phenomenon, based on limited evidence.

Answer: Matter is anything that has mass and takes up space.

Matter can exist in different states, including solid, liquid, and gas.

• Solid
• Liquid
• Gas
• Energy

Answer: Energy

Energy is not a state of matter; it is a property that matter can possess.

Answer: Conducting experiments is important because it allows scientists to test hypotheses and gather data.

Experiments provide evidence that can support or refute a hypothesis.
