Cornell Notetaking: chapter 1 Section 1 “What is Science?” What is Science? A way of learning about the natural world What do scientists want to know? - Scientists want to know why, how, or when something occurred. How do scientists begin? - Finding out begins with Observation and questioning. Asking Questions What isn’t science? Science can answer many questions, but some can’t be answered. Questions about love, art, politics, personal preferences, morality, or religion can’t be answered by science. -Science can’t tell what is right, wrong, good or bad. Flow chart (Possible Explanations) Science can only only answer questions with the information available at the time. Question one explanation possible outcomes New Information = 4 Still possible, modified, thrown out, New possible explanation What is a scientific An attempt to explain a pattern observed repeatedly in the natural theory? world is called a scientific theory. - Theories must be supported by observations and results from many investigations. - They are the best explanations that have been found so far. - Theories can change as new data becomes available EX: Theory of evolution, Cell Theory, Big Bang Theory What is a scientific A rule that describes a pattern in nature is a scientific law. law? - Must be observed repeatedly Cornell Notetaking: chapter 1 Section 1 “What is Science?” - Must be observed repeatedly Does not explain why or how Just describes a pattern A LAW NEVER FAILS THE TEST! Example: EX: Law of gravity, Law of Motion, Rising and setting of the sun, changing of the leaves in the fall What is a system? A system is a collection of structures, cycles, and processes that related to and interact with each other. - The structures, cycles, and processes are the parts of a system. Example: EX. Stomach is on of the structures of your digestive system. Lunch system at school, Ecosystem Do parts of systems interact? Parts of a System Interact - Structures, cycles, and processes interact. - Schedule influences where you go and what time you go. - Can’t complete a test without a pencil. Are there parts of a system that makes up a whole? Parts of a Whole - All systems are made up of other systems. Example: EX: human body has other systems, School is part of a county wide system and state system, a pond ecosystem is part of a larger ecosystem. How do scientists study a system? Scientists break down parts of systems to study. Example: EX: 1 animal, effect of construction on plants What are the 3 branches of Life science, earth science, and physical science Cornell Notetaking: chapter 1 Section 1 “What is Science?” science? What is life science? What do life scientists study? The study of living systems and the ways in which they interact is life science. - Living organisms - Where they live - How they interact Examples: Health field Biologists Zookeepers Botanists (plants) Farmers Beekeepers What is Earth Science The study of earth systems and the systems in space is Earth Science What do earth scientists study? - Nonliving things: rocks, soil, clouds, rivers, oceans, planets, stars, meteors, and black holes - Weather and climate systems that effect earth Examples: EX: Meteorologists, Geologists, Volcanologists What is Physical Science? The study of matter and energy is physical science. - Matter is anything that takes up space and has mass. - The ability to cause change in matter is energy. What are 2 fields of study? Careers? Chemistry – study of matter and the interactions of matter Physics- study of energy and its ability to change matter. - Physicists and chemists - Ultrasound and x-ray technicians SCIENCE AND TECHNOLOGY Cornell Notetaking: chapter 1 Section 1 “What is Science?” What is technology? Technology is the practical use of science or applied science. - Engineers apply science to develop technology - Use of energy of sunlight to produce new technology solar panels.
