Water Cycle

materials
6 ml salt
hot water
ice



create sea by adding 6 ml to 500 ml hot water microwaved pour into plastic beaker put small beaker in larger beaker cover with plastic wrap to speed up process and keep heat in (greenhouse effect) ice placed on  to simulate the coldness of high-level sky

large beaker filled with salt water covered by plastic wrap with ice on top with a smaller beaker inside wieght down to the bottom by lead bbs

This models what happens to salty water releases pure water vapor when hot condenses, in this case on plastic, but in the air dust, to eventually peceipitate pure h20
problems

• great valley sinking bc draining aquifers too fast
• salton sea evaporating raise salinity killed of fish lots of dust poses a health risk and loss of place to stop for 400 bird species

New vocab

• sublimation snow to vapor in 1 step dry cold low-pressure
• transpiration water evaporating trough stomata in plant leaves
