Lesson 1: Introduction
- Observations and Measurements
- Observations - information received from any of our five senses
- Instruments - used to extend our senses
- Measurements - observations made using and instrument
- U.S. Customary Measures (Standard System):
- Length: Inch, Foot, Mile
- Mass: Ounce, Pound, Ton
- Time: Seconds, Minutes, Hours
- Temperature: Degrees Fahrenheit
- Length: Inch, Foot, Mile
- International System of Units (Metric System):
- Length: Meters
- Mass: Grams
- Time: Seconds, Minutes, Hours
- Temperature: Kelvin, Degrees Celcius
- Metric Prefixes:
- Milli, Centi, Deci, Unit, Deca, Hecta, Kilo
- Milli, Centi, Deci, Unit, Deca, Hecta, Kilo
- Length: Meters
- Observations - information received from any of our five senses
- Earth Science - the study of our planet,
its changing systems and its place in the
universe
- Geology - the study of rock
materials and how the solid
Earth changes
- Meteorology - the study of the
changing conditions of Earth's
atmosphere
- Astronomy - the study of Earth's
mostions and the nature of other
objects in space
- Geology - the study of rock
materials and how the solid
Earth changes
- Exponential Notation
- M * 10^n
- Let M = a number from greater or equal to 1 and less than 10
- Let 10^n = any power of 10
- Let M = a number from greater or equal to 1 and less than 10
- M * 10^n
- Observations and Inferences
- Inferences - conclusions drawn from observations
- Based on a wide range of observations = Reliable
- Based on a wide range of observations = Reliable
- Inferences - conclusions drawn from observations
- Percent Deviation
- Percent Deviation (Percent Error) - a convenient way of comparing a measurement to
the commonly accepted value for that measurement
- Deviation (%) = [(difference from accepted value) / (accepted value)] * 100
- Percent Deviation (Percent Error) - a convenient way of comparing a measurement to
the commonly accepted value for that measurement
- Types of Graphs
- Line Graph
- Based on a coordinate system
- Set up on a vertical (Y) axis and a horizontal (X) axis
- Y axis - Dependent Variable
- X axis - Independent Variable
- Based on a coordinate system
- Pie (Circle) Graph
- Used to show how an entire quantity is divided into several parts
- shows the comparison for each part
- Used to show how an entire quantity is divided into several parts
- Bar Graph
- Used to show data that is not continuous
- Set up on a vertical (Y) axis and a horizontal (X) axis
- X axis - Independent Variable
- Y axis - Dependent Variable
- Used to show data that is not continuous
- Line Graph
