Study Guide for Science Unit 1 Test: Water Cycle and Weather
Thursday, Sept. 26
This test will count twice.
You can also use pg.166-222 in the science book as an additional resource,
however not all material on those pages will be tested. Students should also
have several pages of notes and diagrams in their binder. What is on the
study guide will be what is assessed.
Vocabulary to Know
*Condense-the process of a gas changing to a liquid
*Freeze-to change state from a liquid to a solid
*Melt-to change state from a solid to a liquid
*evaporation-liquid changing slowly into a gas
*precipitation-water that falls from clouds down to Earth
*Temperature-a measure of how hot or cold something is
*water cycle- the constant movement of water between Earth’s surface and
the atmosphere
*atmosphere- blanket of gases that surround the earth
*Humidity-the amount of water vapor in the air
*air pressure- the force of air pushing on a area
*climate-pattern of seasonal weather that happens year after year.
Other Information to Know
*Water freezes at 32 F and 0 C; water boils at 212 F and 100 C
*The three states of water are solid, liquid, gas
*Four forms of precipitation are rain, snow, sleet, and hail
*We live in troposphere layer of the atmosphere. All weather happens here.
*Deserts which are very dry have low humidity and wet areas have very high
humidity.
*In the same space, cool air weighs more than warm air. That is why warm
air rises.
*Climate is the average weather in a certain place for a long period of time.
*Weather is the condition of the atmosphere at a particular time and place.
*Large areas of air that have the same properties are called air masses.
*Fronts are the boundary between two air masses that have different
temperature
*Warm Front- when a warm air mass pushes into a cold air mass.
The warm air will slide above the cold air. The cold air will move out.
*Cold Front-when a cold air mass pushes under a warm air mass,
forcing the warm air upward quickly. This usually brings stormy weather and
cold air remains when weather has cleared.
Stationary Fronts- when the boundary between two air masses
do not move. This usually will bring several days of rain
(Pictures of the fronts are on pg. 209 in the science book)
*Most fronts in the USA move west to east.
*A Meteorologist is a scientist that studies weather. They use maps and
weather instruments to predict the forecast.
Weather Instruments to know. (There will be pictures and descriptions.
Pictures can be located on pg 200-201 in the science book)
Wind vane-shows wind directions
Thermometer-measures air temperature
Rain Gauge-measures the amount of rainfall
Barometer-measures air pressure
Anemometer-measures wind speed
Hygrometer-measures how much water is in the air (humidity)
Short Answer. Students will pick two of the four questions to answer. Each
answer will need to be a minimum of three sentences. Answers need plenty
of details so that I understand the student’s thinking. (These will count for
more points on the test)
1. How is climate different from weather?
2. Explain the water cycle. Include words associated with the water
cycle.
3. If you were going to take a trip in a hot air balloon, what weather
instruments might you look at and why? (More than one needed)
4. Why do you think weather usually becomes cool and clear after severe
thunderstorms?
