Kites flying high

The day that our class went to fly our kites was a great lesson on winds. From this experiment we had learned how kites, planes, or birds fly. An object must first be aerodynamic to fly so it will not drag in the wind and crash. There are also certain winds for planes that has such a strong current that it saves the planes by it drifting these are called trade winds. Not all of the kites that had been made was flying because of their characteristics. My kite had flew well for about 10 seconds then it would wouldn't fly.

where water goes with weather

In class the other day we had done an experiment with weather and water. The main idea was to show where evaporation, rain fall, and humans affects each water supply. Also in the middle of this experiment blue food dye had been added from man-made sources that represents pollution. By the end of this experiment almost every water source had pollution. As a result of the experiment, humans and manmade objects and places had most water in their supply. While this happened the other water sources had been severely depleted. This was a good learning and hands on activity. It was pretty fun.
