*Refer to SEPUP Book (online) and your Science Journal - review lab activates and for weather &
climate.
Scientific Method: is a series of steps used to investigate a problem
 Purpose: is the reason for the experiment
 Hypothesis: is an educated guess
 Materials: is the list of supplies needed for the experiment
 Experiment/procedures: are the step by step instructions to conduct the investigation
 Variable: any factor that can be changed in an experiment
 Independent variable: is typically the variable representing the value being
manipulated or changed.
 Dependent variable: is the observed result of the independent variable being
manipulated.
 Constant: factors that will need to be kept constant/the same in an experiment.
 Control: Control is the portion that you are not performing experiments on and is
used for comparison.
 Analysis: is the organization of the collected data into graphs and explanations
 Conclusion: at the end of a scientific investigation a conclusion interprets the results. It
is the claim, evidence and reasoning summary of what resulted. Was your Hypothesis
correct?
Weather - The condition of the atmosphere, including temperature, precipitation, and cloud
cover, at a particular time and place.
Climate - The average weather for a place over a long period of time (usually at least 30 years).
Hydrosphere - is the total amount of water on a planet. The hydrosphere includes water that is
on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid,
vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and
rivers.
Ocean current - Regular movements of large amounts of water in the ocean.
Salinity - A measure of the amount of salt dissolved in water.
Solvent - A substance that dissolves other substances. Water is an excellent solvent and is
known as the universal solvent, because it is capable of dissolving a variety of different
substances.
The Sun is the main source of Earths heat.
Cloud - A visible collection of water droplets in the atmosphere. Clouds usually form hundreds
of meters above Earth’s surface but fog is a cloud formed near Earth’s surface.
Precipitation - The movement of water, in solid or liquid form, from the atmosphere back to
the surface of the earth. Rain, snow, sleet, and hail are examples.
Water cycle - The movement of water from one state to another as it circulates through the
earth’s crust, oceans, and atmosphere. Water evaporates from the surface, rises and cools at
higher elevations, condenses as rain or snow, and falls to the surface where it collects in lakes,
oceans, soil, and rocks underground.
How water changes form/state:
 Evaporation - The process of change in state from a liquid to a gas.
 Melting - To change from a solid to liquid state.
 Freezing - To change from a liquid to a solid state.
 Condensation - The process of change in state from gas to liquid, or the droplets of
liquid formed from this process.
