system A group of related parts that work together mass The amount of matter in an object
troubleshooting The process of analyzing a design problem weather occurs volume The amount of space an object takes up
prototype A working model used to test a design conversion factor A conversion factor is an equation that shows how two units of measurement are related
risk benefit analysis-The process of evaluating the possible problems of a technology compared to the expected advantage variable A factor that can change in an experiment
metric system A system of measurement based on the number 10 data Facts figures and other evidence gathered through observations
hypothesis A possible explanation for set of observations or answer to scientific questions most be testable pollution Harmful substances in the air water or soil
environmental science The study of natural processes that occur in the environment and how humans can affect them renewable resource A resource that is either always available or naturally replaced in relatively
atmosphere layer of gases that surrounds Earth nonrenewable resource A natural resource that is not replaced in a useful time frame
ozone Oxygen gas, O2, is made up of 2 Oxygen atoms. Ozone, O3, is made up of 3 Oxygen atoms. "The ozone layer" refers to the ozone within the stratosphere, where over 90% of the earth's ozone resides. barometer An instrument used to measure changes in air pressure
ozone layer The layer of the atmosphere that contains a higher concentration of of ozone then the rest of the atmosphere greenhouse effect The process by which heat is trapped in the atmosphere by water vapor, carbon dioxide, methane and other gases that form a “blanket” around Earth
drought A long period of scarce rainfall anemometer An instrument used measure wind speed
Coriolis effect The change that earth’s rotation causes in motion of objects and explains how winds curve psychrometer An instrument used to measure relative humidity consistion of a wet-bulb thermometer and dry-bulb thermometer
6 Steps of the Technology Design 1.Information Gathering 2. Planning 3.Design 4.Development 5.Testing and Delivery 6.Maintenance SI Units for the following mass- Kilograms 2.temperature-degree 3.length- meter
What is the goal of technology? to make it easier to access data What are the two most abundant gases in our atmosphere? Nitrogen and oxygen are the most abundant in the atmosphere. 78.08% Nitrogen, 20.95%Oxygen,
Why is the atmosphere important to us? The atmosphere is important for two main reasons. It is the air that you breathe so, no atmosphere, no breathing. The other reason is it protects you by burning up the meteoroids that could hit earth. In which layer of the atmosphere does our weather occur? troposphere
In which layer of the atmosphere is the ozone layer? stratosphere What does the ozone layer protect us from? The ozone layer protects us from the sun's powerful rays.
What causes wind? The pressure gradient force, which arises from the uneven heating of earth's surface horizontal axis A coordinate system in which the coordinates of a point are its distances from a set of perpendicular lines that intersect at an origin, such as two lines in a plane or three in space
vertical axis The vertical line near the center of gravity of a craft, perpendicular to both the longitudinal and lateral axes, around which it yaws.
obsolete No longer in use density The amount of mass of a substance in a given volume
patent A legal document issued by the government that gives an inventor exclusive rights to make use or sell an invention for a limited time scientific theory A well-tested explanation for a wide range of observations of experimental results
