Students got to see the water cycle happen right in front of their eyes. A pot of water was placed on a burner. The burner represented the sun. Students quickly understood that without the sun, there would not be a water cycle. The heat made the water boil and change into steam or water vapor. The steam represented evaporation. An aluminum tray filled with ice cubes was directed over the steam. The ice cubes represented the cold temperature of the atmosphere. Water droplets formed on the bottom of the tray introducing condensation. Students understood the concept of warm meeting cold which creates water droplets. Once enough condensation was created, the droplets fell because of gravity and precipitation was formed. Finally, a tray on the table collected puddles of water...accumulation. Camille replied, " I think it was very cool and the fifth graders next year will like it too!" Nico stated, "The water cycle demo was well thought out, but it could have used more details for accumulation like a "river" flowing back into the steam pot. Overall, it was the best science demo I have seen in a long time."
I hope you enjoy learning how the garden changes throughout the school year.
