Study Notes
Module Two: The Impact of Science on Society
- Module focuses on the ways science impacts today's society, including energy production, health, disease, information technology, and biological/biotechnological research.
- Activities rely on energy, directly or indirectly.
- Industries in the Caribbean depend on energy.
- Reliable energy sources are crucial for productivity and well-being in society.
- Understanding life itself, its conditions, and management is important for societal well-being.
- Ethical considerations are crucial when exploring life issues.
- Information technology significantly shapes how society organizes and communicates.
- The Caribbean is no exception, with daily interactions through the internet, cell phones, and cable television.
- Understanding information technology is crucial for societal interactions.
- The module is divided into six units: basic scientific concepts, energy production and use, health and disease in the Caribbean, biotechnology and society, information technology and society, and some ethical and gender issues.
- Each unit is divided into sessions that cover topics/concerns.
Unit 1: Basic Scientific Concepts (Brief Introduction)
- Matter is composed of very small particles (atoms, molecules, ions).
- The atom is the fundamental particle of matter.
- Atoms consist of electrons, protons, and neutrons.
- Electrons orbit the nucleus (containing protons and neutrons).
- Atoms combine to form molecules.
- The arrangement of atoms and bonds affects the properties of substances.
- Molecules combine to form large molecules (e.g., proteins).
Unit 1: Atomic Structure and the Structure of Matter
- The fundamental particle of matter is the atom.
- Atoms consist of subatomic particles called electrons, protons, and neutrons.
- Protons and neutrons are found in the nucleus of the atom.
- Electrons orbit the nucleus.
- Atoms use their outer shells (electron shells) to form bonds.
- Properties of compounds/molecules depends on the way atoms bond.
- Scientists use models to illustrate the arrangement of atoms and bonds within molecules.
- The number of protons in the nucleus determines the nature (element) of an atom.
Unit 1: Nuclear Energy
- The nucleus of an atom contains a large amount of energy.
- Some elements have more energy in their nuclei than others.
- Large nuclei splitting into smaller fragments, with mass loss, releases a significant amount of energy.
- Chain reactions are involved to release energy from nuclei in a controlled manner (in power stations) or large quantities at once (in bombs).
Unit 1: Electricity
- Electricity is a form of energy caused by charged particles (protons and electrons).
- The rate of flow of charged particles is measured in amperes.
- Batteries have a pumping force (voltage) that determines the rate of charge flow.
- Metals are good conductors.
- Different substances have different conducting properties.
- Generators convert mechanical energy into electrical energy.
- Turbines are engines use by generators.
Unit 2: Energy Production and Use
- Work is done when a force moves an object.
- Energy is needed to do work.
- Energy exists in various forms (kinetic, potential, thermal, nuclear).
- Kinetic energy is the energy of motion.
- Potential energy is stored energy (due to position or state).
- Thermal energy is heat energy.
- Nuclear energy is energy from atomic nuclei.
- Energy is the ability to do work.
- Many activities or processes need energy.
- Humans, plants, and machines require energy to perform actions.
- Burning fuel to drive machines is a common form of energy production.
- Energy production can lead to some environmental issues.
Module Two: The Impact of Science on Society
- The module explores the various forms and sources of energy.
- Traditional and newer forms of energy production.
- The role of energy in industrial activity within the Caribbean.
- The implications of energy use for the economy and environment.
- Understanding energy consumption and need for conservation.
