Study Notes
Characteristics of Living Things
- Exclusive characteristic: Living things exhibit complex organization and a high degree of order at different levels. Non-living things may possess structure but lack this intricate organization.
- Energy production: Living things engage in metabolism, a series of chemical reactions to produce energy needed for life processes. This process is absent in non-living entities.
- Non-living characteristics: Non-living things do not exhibit growth and development. While some non-living things may appear to grow, this process is a result of external factors, not internal changes.
- Interaction with environment: Living things actively interact with and respond to their surroundings, adapting to changes and maintaining internal stability. This dynamic relationship with the environment distinguishes them from non-living entities.
- Key function: A key function of living things is reproduction, passing on their genetic information to create new individuals, ensuring the continuation of their species.
Living Organisms
- Study of animals, plants, and microorganisms.
- Characteristics of life include growth, reproduction, response to stimuli, and metabolism.
- Classification of living organisms includes mammals, reptiles, amphibians, fish, birds, and plants.
Ecosystems
- A community of living organisms and their environment.
- Components include producers (plants), consumers (animals), and decomposers (fungi and bacteria).
- Food chains and food webs illustrate the flow of energy in an ecosystem.
Matter
- Anything that has mass and takes up space.
- States of matter include solid, liquid, and gas.
- Changes in states of matter include melting, freezing, evaporation, and condensation.
Energy
- Types of energy include kinetic (motion), potential (stored), thermal, electrical, and chemical.
- Law of Conservation of Energy: energy cannot be created or destroyed, only transformed.
Earth's Systems
- Geosphere (land), hydrosphere (water), atmosphere (air), and biosphere (life).
- Interaction of systems leads to weather patterns, erosion, and the water cycle.
Solar System
- Components include the sun, planets, moons, asteroids, and comets.
- Planets are categorized as terrestrial (rocky) or gas giants.
Scientific Method
- Steps include asking a question, conducting background research, forming a hypothesis, conducting experiments, collecting data, analyzing results, and drawing conclusions.
Experiments and Observations
- Accurate measurements and documentation of findings are crucial.
- Different types of investigations include controlled experiments and field studies.
Weather and Climate
- Weather refers to short-term atmospheric conditions.
- Climate refers to long-term average of weather patterns.
Natural Resources
- Types include renewable (solar, wind, water) and nonrenewable (coal, oil, natural gas).
- Conservation and sustainable practices are essential for responsible resource use.
Scientific Tools
- Common tools include microscopes, telescopes, scales, thermometers, and beakers.
- They play a vital role in experimentation and data collection.
Engineering and Design
- Problem-solving through the engineering process: define, imagine, plan, create, improve.
Lab Safety
- Importance of following safety rules: wear goggles, handle tools properly, understand MSDS (Material Safety Data Sheet).
- Emergency procedures: know exit routes, location of first aid kits.
Science in Daily Life
- Science is essential in technology, health, and the environment.
- Everyday applications of scientific concepts (e.g., cooking, energy use).
