3. Day 1- Cohesion and Adhesion Whenever I’m out alone on the water like today, I always look at fishing as a simple man’s job. And being the simple man that I am I’ll start with one of the most simple properties; cohesion. Cohesion is what I see everyday. This property says that water has a tendency to stick together. All bodies of water only exists because all molecules of water stick together. Without water’s property of cohesion, I wouldn’t be able to do what I love. And besides this, there is the property of adhesion. This property says that water sticks well to other objects. As a fisherman, I see this all the time as well. Water sticks to my fishing pole, me, and my boat, which is a hazard for all fishermen, and is the reason why I where a lifejacket.

4. Day 2- Polarity and Hydrogen Bond Looking deeper into the water waiting for a nibble, I thought more about a singular water molecule. As I thought about the make-up of water, H2O, while hydrogen atoms(H) are positive, and oxygen atoms(O) are negative. These two atoms attract, and form a +/- bond like a magnet. This is a hydrogen bond, which happens between different water molecules. Covalent bonds happen when the water molecules are created. This is shown by the black line in the diagram. Along with this is polarity. This is the property of water that makes one end of the molecule positive and one end negative.

5. Day 3- Waters density and Surface Tension Today, I was fishing with a bobber and I thought more about what makes a bobber float on the surface. There are two properties of water that could be the reason that objects float. If an object is less dense than the liquid it is sitting on, it will float. Waters density is 1 g\ml. With this information, we know that the density of my bobber is less than 1 g\ml. Another property that allows objects to sit on top of water is surface tension. Surface tension is a property that is a result of polarity. When water molecules sticks together, it makes water act as if they were covered in a thin solid. This allows some animals to skate on top of the water.

6. Day 4- Specific Heat and the Water Cycle Today was a very cold day for the season, and the fish were not very active. Like humans, the fish like to conserve their body heat by being in motion less. The property that affects the heat of water is called specific heat. Specific heat is the amount per unit mass needed to raise the temperature one degree Celsius. Specific heat also affects the water cycle. When water evaporates, its specific heat must reach a certain temperature in order to turn into a gas. When in the water cycle, water is evaporated, condensed into a cloud and then precipitated back to the ground.

7. Day 5- Universal Solvent and Capillary Action Today after cleaning up the catch of the day, I went back to the boat and started to rinse it of. At first I used buckets of the salt water and observed one carefully. “How does the salt stay in the water?” I thought to myself. I learned then that water is a universal solvent. Water can dissolve more substances than any other liquid. Now knowing that I was rinsing off my boat with salt, I took the hose off of the dock. As I pulled the hose up to the boat a kink formed. While straight up in the air, the water in the hose was still halfway up in the narrow tube. This is because of capillary action. Capillary action is the tendency of a liquid to climb up narrow tube thanks to cohesion, making the water stick together and adhesion, making the water stick to the inside of the hose.

8. Fun Facts 1. 70 percent of an adult’s body is made up entirely of water. 2. Nearly every food or drink item provides some water to the body. 3. 70-75 percent of the Earth’s surface is covered in water. 4. The average person in the United States uses about 80-100 gallons of water each day. 5. The United States uses about 346,000 gallons of water each day.
