Water Cycle Fun!

For the past few weeks, we have been learning about the water cycle. The water cycle is the movement of water from Earth's surface into the air and back again. As water moves through this continuous cycle, it changes forms. The Sun's energy (heat) causes water to evaporate and become water vapor. Water vapor rises into the cooler air and turns into water droplets or ice crystals. Water vapor in the air that turns back into a liquid is called condensation. Water that falls to the Earth is called precipitation.
On Wednesday, we brought the water cycle into our class....sort of. We set up a demonstration using a heating element (representing the Sun's heat), a tea kettle filled with water and a tray full of ice (representing the cool clouds). We found that when the water evaporated and rose to the "clouds" that condensation was formed and in turn, we created precipitation. Need a visual? Click on the video below.

Also, take a look at the following video for an explanation by one of our friends about what he learned regarding the water cycle.

Learning about the water cycle has been so much fun. We have also learned a really fun song about the water cycle and we will be making water cycle bracelets. I am glad that you were able to take a peek into our classroom. Thanks for reading!

Dear Miss Russell, right now I am showing my grandpa our science experiment about how it rains!And so far he is enjoying it and wants to see more like this one.
