Essential Understandings:
•When liquid water evaporates, it turns into water vapor in the air and can reappear as a liquid when cooled or as a solid if cooled
below the freezing point of water.
•Global patterns of atmosphere movement influence local weather.
•Weather can be described by measurable quantities, such as temperature, humidity, wind direction and speed, and precipitation.
•Weather changes from day to day and over the seasons.
•In gases, the atoms or molecules have still more energy and are free of one another except during occasional collisions.
•In liquids, the atoms or molecules have higher energy, are more loosely connected, and can slide past one another; some
molecules may get enough energy to escape into a gas.
•In solids, the atoms are closely locked in position and can only vibrate.
•Increased temperature means greater average energy of motion, so most substances expand when heated.
•Atoms and molecules are perpetually in motion.
•Most substances can exist as a solid liquid or gas depending on the temperature.
•Heating and cooling cause changes in the properties of substances.
•Oceans, seas and large lakes have a major effect on climate, because water in the oceans holds a large amount of heat.
•Oceans, seas and large lakes can influence local weather conditions.
•The angle the Sun’s energy hits the Earth causes weather.
•Water vapor in the air moves from one place to another and can form fog or clouds, which are tiny droplets of water or ice, and can
fall to Earth as rain, hail, sleet or snow.
