I have created a simulation that shows a very basic model of the Water Cycle. However, as you will notice, my evaporation arrow does not work! Can you program it to move up to where the cloud goes to complete the cycle? Extension: Can you add other details about the water cycle? You could research and add to this, or you could also add other images and even sounds. We could add the thunder and lightning after it woke us up last night! Enjoy the challenge.
