Potential and Kinetic Energy PE=WxH W=10xM V(avg)=d/t V=2xV KE=mvxmv Summary: The potential energy was faster at the bottom of the ramp because as the car had gone down the ramp, it gained speed and the potential energy was greater. However, there was less energy at the bottom, because it had gone through an energy conversion, and some of the energy went into thermal and sound energy. The reason for this is that energy is neither created nor destroyed, so the energy is turned into thermal energy.

The energy saving lab We are trying to find the heathier ways to make electricity, that are more eco-friendly to the enviorment. Some examples are Solar, wind, hydroelectric, and nuclear.

The U.S. mostly depends on nonrenewable resources. These resources will eventually run out, and we will be forced to use renewable resources. We should switch to renewable resources as soon as possible because the longer we use nonrenewable resources, the worst the environment will get. The Earth’s temperature is rising because of the burning of fossil fuels. In this passage, we will tell you about a nonrenewable resource called nuclear energy, that is bad for the environment, and 3 good renewable resources called solar, wind, and hydroelectric energy. The U.S.’ nuclear energy is about 19 percent of its energy production. Uranium is used for nuclear energy, and is a nonrenewable resource. Great amounts of water are used for cooling, which can affect forms of life where the water comes from. Also, the waste from nuclear energy can build up in rivers and streams. The radioactive wasted is stored in barrels which are placed in steel- lined concrete vaults. Finally, building power plants can destroy habitats and contaminate the land. Over thousands of years that we have had the sun, we barely started to harvest it. Just because it is 150 million miles away, that does not mean that it is not powerful. One hundredth of a millionth of the sun’s energy is enough power to meet all of our needs. Every minute the sun shines on us. We have enough energy to meet our energy needs for a whole year. The problem is we are not harnessing it right. Another problem is the price of solar panels is high, even though it will start to pay off in 10 years. If we could get everyone to buy these, people would be saving money on their electric bill, and the solar panels are eco friendly. Remember, solar energy is free and it does not pollute. It also saves a lot of electricity and is handy for charging batteries. There is only one problem; it does not work at night. Hydro power provides a clean source of energy with a continuous renewable source: water. The kinetic energy in flowing water can be converted into electrical energy. Hydroelectric power plants force water through a hydraulic turbine connected to a generator. The water leaves the turbine and is returned to a body of water below the dam. Hydropower depends most on rain ad elevation, which is why the Pacific Northwest has more productive hydro electric power plants than the Gulf Coast, which is completely flat. Another form of hydro power is micro hydro power, which is similar to hydro power, but does not use a dam to direct water. Micro hydro power uses smaller river systems called run of the river systems. Micro hydro power works by diverting water from a river or stream into a valley and then dropped into a turbine called a penstock. The penstock operates a generator that provides power to the local community. Micro hydro power is also available in batteries, giving locals a clean, portable source of energy. Nonrenewable resources do not last forever, and we need to find another source of energy.

Chemical Lab

Q. What happens to the different materials when they are placed in water? H. We believe that the copper sulfate will make a solution, the zinc oxide will be a suspension, the sucrose would be a solution, the sulfur will be a suspension, and the tang will be a solution. IV. The different materials DV. The mixtures that it will make when it is mixed with water C. the amt of solid, the amt of liquid, filter, temp of water.  Name || Zinc Oxide || Copper II Sulfate || Sucrose || Sulfur || Tang || We got this information mostly from wikepedia Zinc Oxide: An inorganic compound with the formula ZnO, it is not safe to inhale in any way, and it is used in paints and ceramics Copper II Sulfate: It is a compound, its formula is CuSO4, and is used as a herbicside, pesticide, and fungicide. It is also an irratant, and very toxic Sucrose: It is an organic compound, its formula is C12H22O11, and it is known as table sugar, so it is safe to eat Sulfur:It is an element, its formula is S, atomic number 16, and it is not safe, because it is used in explosives Tang: It is an edible drink mixture, and it has no formula

After mixing them with water, these are the results we get: Zinc Oxide:It becomes a suspension, because when we had mixed it, the particles settled out, and you could see the two different substances. Copper II Sulfate: It became a solution, and when this happened, you could see it mix together, and you could see right through it. Sucrose:As we mixed it together, the substances mixed, and the sucrose melted into the water, making it a solution. Sulfur: When you mix the sulfur together, the particles stayed either floating, or sinking, and it would not mix, so it was a suspension. Tang:As we mixed the tang, the water fizzed a little bit, and the water changed color. This means that the substance spread evenly throughout, so it had become a solution.
