Introduction to Earth Science
What is Science? Science is the process of observing and studying things in our world Based in making observations and conducting experiments
What are the Pure Sciences? Biology Chemistry Physics
How is Earth Science Different? Earth Science is an Applied Science Earth scientists use the knowledge and methods of chemistry, biology, and physics to investigate real world problems and events
Who is probably NOT doing science? An artist making an abstract painting A student measuring the mass of a mineral sample A surveyor determining the boundaries of a building lot An astronomer looking for the most distant stars and galaxies
What is Earth Science? universe changing Earth Science is the study of the Earth and its place in the _________________ Our Earth is constantly ________________ universe changing
Earth Science is Dynamic What does it mean for something to be “dynamic?” As we refine our methods and apply new ideas, we make new discoveries that change the methods of Earth Science What are some examples about Earth Science that you guys know about that make it dynamic? (weather, erosion, earthquakes, seasons, etc. everything is always changing!) As science gets more advanced, we are able to learn more and more about our earth
What makes up Earth Science? There are FIVE main areas of study that make up Earth Science: Geology Meteorology Astromoy Oceanography Environmental Science

What is an observation? senses instruments An observation is the information obtained directly using our ___________ We use __________________ to extend our senses and make our observations more precise senses instruments
What is an Inference? interpretation An inference is an __________________ of an observation interpretation
Which of the following is NOT an observation? The plant has grown 3 inches in two weeks The plant has purple flowers The plant has grown because it has been watered every day The plant does not have any leaves
What is a Measurement? accuracy A measurement is a way to express an observation with greater _____________ or precision Example: It is cold out today. -- NOT a measurement It is 35°F today. -- measurement accuracy
What is a Classification? A classification is a grouping of items by ________________ similarities
Dynamic Equilibrium balance Dynamic Equilibrium occurs when opposing forces in the environment _____________ each other out Example: The amount of oxygen in the atmosphere is stable. balance
