Overall the trip to Cloe Lake was successful. We were able to collect all of the data we needed. The procedure included: 1. Air temperature 2. Water temperature 3. Width of the stream at 4 different intervals 4. Depth of the stream at 4 different intervals 5. Velocity of the stream

The data is the most important part of the trip. An example would be the temperatures in and out of the water. Outside of the water it was 11 degrees Celsius and 13 degrees Celsius inside of the water. The temperature around the water was in a decent range for most organisms. However if the temperature of the water were higher it would be able to support more life. Knowing what the forest around the stream is made of is important as well. Made of decomposing leaves, the forest floor is called humus. It provides habitat and food for living organisms such as trees, mammals, insects, and other small plants. Keeping this area clean is important not only for the animals that live there, but for us as well. Some of the pollutants that humans leave behind in the forest can run off into the stream. That stream will then carry those pollutants down into a larger body of water, and that large body of water can possibly a water source for us. GPS navigation is handy if you are exploring the country or going on a long trip. GPS stands for Global Positioning System. It works by four or more satellites sending a signal to a GPS unit. It then determines where you are located using latitude and longitude and the current time. This useful information can be used to play games like Geocaching. Geocaching is real-world treasure hunting game. Players try to locate hidden containers, called geocaches, using their GPS device and a set of coordinates. They then share their experiences online. We were lucky enough to experience little problems when we were measuring. A minor problem we found was that the ground was full of rocks so the stakes were difficult to pound in to measure the stream width. Because of the stakes being loose half of the time, the rope would come undone continuously. Finding the velocity of the stream was difficult as well. There was a large rock in the way that when we sent the tennis ball downstream, it would get stuck near the rock and slow down the process. It rained on and off all day but that did not slow us down. It was hardly an inconvenience for this overall successful trip.
