To make the model, he stacked some big books on the floor. Next, he took some of Alex’s small building blocks and put them on the floor next to the stack of books. Josh told Alex that each block was a tiny bit of water, and together the blocks made up a puddle. Josh explained bits of water left the puddle and went up into the air. So, Josh took the blocks one at a time from the pile and placed them on the stack of books. When all the blocks were on the stack of books, Josh pushed the blocks close together. He told Alex that the bits of water in the air now formed a cloud. Next, Josh asked Alex to gently push the blocks off the books. Alex did. As the blocks fell, Josh told Alex that the falling blocks were like rain. Josh swept the blocks together into a pile on the floor with his arm. When the blocks were gathered together again, Josh told Alex that the bits of water were back in the puddle, and could move up to the stack of books again. 1) Diagram Josh’s model of the water cycle and label the stages: evaporation, condensation, precipitation, runoff, and collection. 2) What adds energy to the water cycle at the stage when the bits of water move up into the air? 3) What force causes the bits of water to fall back down to Earth’s surface? 2nd six weeks review Page 20 of 33 80.
