For the second part of this week’s lab, I made a quick trip to the small local hardware store to purchase a galvanized nail and small piece of copper wire. My grand total was very affordable at 20 cents. 1. One large orange 2. One 2-inch-long galvanized nail 3. 2-inch-long copper wire 4. String of holiday Christmas lights 5. Needle nose pliers Procedure To start this lab experiment, I gathered all the supplies needed and placed them onto my kitchen counter (see picture). First, I took the…

Wireless technologies have transformed our lives greatly. Until a few years back, we needed a wired computer connected to telephonic ports to get internet access. Nowadays, mobile phones are used for super-fast internet, with applications ranging from banking to movie ticketing. This wireless technology helps reduce cost and also increases mobility. Devices are shrinking in terms of their size and are growing in processing speeds. 4G is the fourth generation of broadband mobile technology after…

those individuals who do not own a vehicle. I believe that the importance of cars that are electrical will reduce pollution because they do not make the same quantity of carbon in their cycle as internal-combustion engine; the must to change the batteries make them a lesser amount of green than the current technological industry. Also, many electric vehicles have a higher chance to reduce carbon dioxide (CO2) and different greenhouse gases in the environment. Therefore, fuels that are harmful to…

They’ll use a nail and a battery to create a magnetic field. It’ll turn the nail into a magnet. Students should be sure to write down their observations throughout the experiment. Students will wrap the center portion of the wire around the nail 10 times so that it forms a coil. They should have extra wire at both ends. Then the students will attach one end of the wire to the (+) terminal of the battery. Then, attach the other end of the wire to the (-) terminal…

MAKING SOLAR ENERGY MORE ECONOMICAL: (SAFETY, WEIGHT BENEFIT, MATERIAL COST AND WOW FACTOR) Noah Garcia, Hongyu Chen, Pablo Bribiesca, Mohammed Ali Our group the Dream Green Team has only one goal in mind. To Make solar energy more economical. To make solar energy more economical a few things can be done. The cost to build solar panels can be decreased, the efficiency can be increased, or the storage of the energy can be more efficient. In the past decade solar panels have been improved…

and you regularly need to replace the air filters and spark plugs. Electric saws are available with a cord that connects to an external power source or with a rechargeable battery. For jobs away from the power sources, choose saws with Lithium ion batteries for extended life and performance that doesn't decrease as the battery discharges. These saws are weight less than gas ones and are environmentally friendly. Both types of saw's blades need regular lubrication, sharpening and adjustments…

The idea for the electric car has been around for several years. EVs, short for electric vehicles, come in four types: the purely battery-operated vehicles, hybrid gas and electric vehicles (plug-in and non-plug-in), and fuel cell operated. These kinds of cars run primarily on electrical power, as opposed to a conventional car that runs on petrol based fuels. Because of this, they are seen as the poster children of green transportation. There has been some debate on whether or not these EVs…

concluded that the rudders did not stabilize the boat and instead just slowed it down, so they were removed. Next the team tested the position of the battery to test if it would affect the trajectory of the vessel; several tests showed that the position of the battery was perhaps one of the most vital design choices. It was discovered that placing the battery on the left ski counterbalanced the boat and caused it to follow a much straighter trajectory reducing the time by almost a second. The…
