Solar System (Stars and Planets)
Water Cycle/Weather Unit
Weather research report
What do they have to know in this unit?
· Water takes the form of a solid, a liquid, or a gas.
· Temperature determines the point at which water changes from liquid to solid, from solid to liquid, and from liquid to gas.
· Adding heat or taking away heat changes the state of water.
· Water freezes at 32 F/0 C and boils at
· 212 F/32 C.
· Evaporation occurs when tiny droplets of water too small to see rise into the air and turn into water vapor. It is the changing of a liquid into a gas.
· Condensation occurs when water vapor cools or loses heat. It is the changing of a gas into a liquid.
· Clouds are formed as water vapor in the air condenses.
· The water cycle is the continuous movement of the earth’s water from the oceans (evaporation) to the air (condensation) and back to the oceans and land again (precipitation).
· Precipitation is water that falls to the earth
· as rain, snow, sleet or hail.
· Rain is liquid water falling from the sky.
· Snow is very small amounts of water (smaller than raindrops) that freeze and stick together and fall to earth.
· Sleet is raindrops that fall through cold layers of air.
· Hail is frozen raindrops which rise and fall many times through warm and cold layers of air, getting bigger each time.
· Fog is a cloud close to the ground which forms when the air is damp and the ground is cold.
What do the students have to do in this unit?
· Identify how water looks as a solid, liquid, and gas.
· Identify and describe the temperatures that change water to different states.
· Give several examples of evaporation and condensation.
· Investigate and describe how clouds are formed through condensation.
· Describe and demonstrate how the water cycle works.
· Identify and describe various forms of precipitation.
Describe the weather conditions that cause fog to occur.
