What is General Science?

1. Course Positioning and Features

The Middle School General Science course is a core subject in Hong Kong international schools, designed for students typically aged 11 to 14. It emphasizes observation, inquiry, experimentation, and critical thinking skills, providing a solid foundation for students who will later pursue specialized subjects such as Biology, Chemistry, and Physics in the IB MYP or IGCSE programs.

Key Features:

• Interdisciplinary Foundation: Integrates knowledge across biology, chemistry, physics, earth, and environmental sciences.
• Experiment-Based Learning: Focuses on the complete scientific process — observation, hypothesis, testing, and analysis.
• Real-World Connections: Addresses global scientific issues such as climate change, health, and energy sustainability.
• STEAM Integration: Combines science with technology, engineering, arts, and mathematics to foster creativity and innovation.

4. Effective Learning Strategies

4.1 Inquiry-Based Learning: The I-E-A-R Model

• Initiate: Formulate questions and hypotheses
• Experiment: Design and conduct experiments
• Analyse: Interpret data and graphs
• Reflect: Draw conclusions and consider applications

4.2 Scientific Language and Graph Skills

Skill Type	Recommended Practice
Lab Report Writing	Use a clear “Method → Results → Discussion → Conclusion” structure
Scientific Vocabulary	Create a “Concept Vocabulary Wall” with terms like condensation, ecosystem, voltage
Graph Analysis	Practice interpreting bar graphs, line graphs, scatter plots to explain trends and anomalies

5. Common Challenges and Solutions

Challenge	Suggested Solutions
Abstract Concepts Difficult to Visualize	Use physical models, math visuals, and animations
Unfamiliar with Experimental Procedures	Practice standard steps early; create “Science Experiment Flowcharts”
Overwhelmed by Too Much Memorization	Use mind maps to connect and organize concepts
