Gear Propulsion Solar Car | ||||
The federal government has encouraged alternative forms of transportation due to a limited supply of oil and increasing environmental pollution. Solar cars are just one of many transportation concepts emerging. Solar cars use solar cell panels instead of gasoline as the fuel. As a result, exhaust fumes and oil consumption are eliminated. The solar cell panel generates an electrical charge that is stored in a battery and used to provide energy as the vehicle is driven. The lighter the vehicle, the less energy used and the farther the vehicle will travel. In cloudy days, or at night, energy can be drawn from reserve batteries. In the future, charge stations will be located on the road sides for quick battery charging. Materials Checklist: Before using the kit please make sure you have all the items listed below. This kit has the supplies to build at least one type of solar car model. Solar cars may be propelled using a pulley/ rubber band method or some types of interlocking gears.
Propulsion systems include using a solar cell and toy motor with a:
Basic Tools Required These items may be required to build the solar vehicle: (You can make your solar car model without them as well)
During the construction of the solar vehicle, the following safety precautions should be observed.
Competition between students can be based on design, drawings, final appearance, distance-traveled, speed, etc. Races can be held between cars that have similar or different types of propulsion Systems. In addition, teachers could implement a problem-solving category for advanced or older students. Teachers would provide students with the solar racer kit then instruct students to make use of additional materials in the classroom to construct a customized solar vehicle. additional items could include wood scraps, stickers, paint, CD, colored wheels and more. How elaborate or complex the solar cars are depends on imagination and resources. Solar car for an experimental science project Solar car may also be used in an experimental science project with question, hypothesis and a results table and chart .A good question for this project is: How does the angle of solar panel in relation to the sunlight affect the performance of the car? Hypothesis: The answer you guess for the above question will be your hypothesis. This is an important question because we can use the result in designing real solar cars. If the angle of the solar panel is important, cars must be designed so that the driver or an automated system can change the angle of the solar panel. If the angle is not important, then the solar panel may be mounted horizontally on the roof of the car. Experiment: In a sunny day, around noon time take your solar car outside on a smooth flat surface. Initially adjust the solar panel to be horizontal. Place the car on the flat surface and record the distance it drives per second. That will be the speed. Then change the angle of the solar panel so that it will have a right angle with the sunlight. Repeat your test again and record the speed again. Report the sunlight exposure angle in which your solar car had the highest speed. Make a graph: You can also make a bar graph with one vertical bar for each of the angles you test. The height of each bar will be the speed of your solar car in that angle. |
