태양전지를 이용한 학습용 모형 거북선의 성능 특성 = Characteristics of the Performance on Model Turtle Boat with Solar Cell for Teaching-Learning

다국어 초록 (Multilingual Abstract)

In this study, we fabricated model turtle-boat with solar cell for teaching-learning and measured operating efficient characteristics on it. An water tunnel was made in order to find the characteristics of performance a model turtle boat. Under the various experimental conditions such as counterweight increasing 10 by 10g until model boat was flooded, the required time to move distance of 3m was measured by stopwatch. The main results and expectation educational effects of this study were as follows :(1) The model turtle boat composed of the body of turtle boat and solar cell to drive it was designed and invented.(2) The fastest speed of the model boat was accomplished 0.25m/s at 50g of a counterweight, and the efficiency was 3.1%.(3) Middle/high school students of our country being surrounded by seas of three sides can be introduced to having interest in the ocean through examining the operating characteristics in a fluid using model boat.(4) Through this study, students can learn the concrete knowledge of engineering and technology something like the ability of design, making, and investigation, and furthermore bring up the process skills in solving the problems.
