Overview of G1 LSS Topics (2021 Syllabus)
Topic: Laboratory Measurements and Procedures
Topic Description: Scientific investigation in the laboratory requires adherence to safety guidelines and proper handling of apparatus. Measurements, both precise and estimated, are crucial for scientific inquiry and everyday applications.
Key Inquiry Questions:
1. Why is it important to observe laboratory safety guidelines?
2. Why is measurement important?
Topic: Force
Topic Description:
Forces, including frictional and gravitational, influence motion and everyday activities. Understanding forces enables the utilization of machines, such as levers, to ease tasks and improve efficiency.
Key Inquiry Questions:
1. How do we use forces to improve our lives?
Topic: Energy
Topic Description: Energy exists in various stores and is essential for work. Machines convert energy from one store/form to another, emphasizing the importance of utilizing resources wisely and exploring renewable energy sources.
Key Inquiry Questions:
1. How do energy conversions enhance our lives?
2. Why is it crucial to reduce energy wastage?
Topic: Electricity
Topic Description: Electricity powers numerous devices, with electrical systems converting energy for practical use. Understanding the flow of electric charges and circuit configurations is vital for safe utilization of electricity. Electricity is typically generated at power stations and transmitted over long distances to power our machines. Due to the high voltage of mains supply, mishandling electricity can pose serious risks to our safety. Therefore, it's essential to implement precautionary measures and utilize safety features to mitigate the hazards associated with electricity usage.
Key Inquiry Questions:
1. How does electricity function, and how can we ensure its safe use?
5. Heat
Topic Description: Heat is a common aspect of our daily experiences, often encountered through various machines like electric kettles. Energy supplied to these machines is often converted into heat, which flows from hotter regions to colder ones. Understanding the effects of heat is crucial for ensuring both safety and the effective functioning of machines.
Key Inquiry Question:
- How does heat and its effects impact our daily lives?
6. Matter
Topic Description: Matter encompasses anything with mass and occupies space. It can be categorized based on properties such as density, acidity/alkalinity, and solubility. Understanding these properties allows for the classification and utilization of different types of matter, as well as the separation of mixtures to obtain specific substances.
Key Inquiry Question:
- How can matter be classified?
7. Water Pollution
Topic Description: Water is vital for our environment, but human activities often degrade its quality, impacting aquatic life and human health. Given Singapore's limited water resources and its proximity to water bodies, understanding our actions' impact on water quality is crucial for maintaining a balanced environment.
Key Inquiry Question:
- What effects do human activities have on water quality?
8. Air Pollution
Topic Description: Air quality is essential for human health and the environment, but both natural and human activities contribute to air pollution. Understanding common air pollutants and their sources is vital, especially in urban areas like Singapore, where rapid industrialization and modern lifestyles increase pollutant emissions.
Key Inquiry Question:
- How do human activities influence air quality?
Understanding the interactions between our environment and ourselves allows us to grasp how our actions can influence air quality. Ensuring environmental balance is crucial for our survival.
9. Cells
Topic Description: Cells serve as the fundamental building blocks of our bodies, requiring a light microscope for observation due to their small size. Different types of cells perform specific functions, collectively contributing to efficient bodily functions.
*Key Inquiry Question:*
- What constitutes the basic building blocks of living organisms?
10. Getting Energy and Nutrients From Food
Topic Description: Food is essential for providing energy and nutrients necessary for bodily functions, growth, and repair. The digestive system breaks down food into smaller substances with the assistance of enzymes, while the circulatory system transports digested food to various body parts for energy release through respiration.
*Key Inquiry Question:*
- How do we extract energy and nutrients from food to sustain our daily activities?
11. Human Reproduction
Topic Description: Reproduction is vital for human continuity and involves intricate interactions among different reproductive organs. Puberty triggers changes in our bodies to enable reproduction, with each reproductive organ fulfilling specific functions. Understanding reproductive health, including infections like sexually transmitted infections (STIs), is crucial for maintaining overall well-being.
*Key Inquiry Question:*
- How does human reproduction occur?
12. Taking Good Care of My Body
Topic Description: Our lifestyle choices significantly impact our health. Drug abuse, excessive alcohol consumption, and smoking have detrimental effects on our bodies, leading to adverse changes in various bodily systems. Educating ourselves about these consequences enables us to make informed decisions and maintain optimal health.
*Key Inquiry Question:*
- What steps can we take to maintain good health and well-being?
