We had quite a diverse group of families, with young kids to teenagers. Our objective was to build an amusement park with Gigo tracks and construction parts. During the workshop the families have went throguh several essential science and physic principles with experiments such as droping balls and pieces of paper to test the free falling body principle and how air resistance may affect the rate of accelaration. When we placed the balls on a track and let them roll, we observed that the force acting upon the balls is decomposed into three different components, namely gravity, upward reaction and friction. As Newton’s third law of motion states, when two objects interact by execting a force on each other, there will be an equal magnitude of reaction force upon collision, but in opposite direction. Through observations of colliding balls, we saw Newton’s laws of Motion in action. The greater the mass of the colliding object and accerlaration, the greater the force upon impact. By using different Gigo parts, the families were able to build their very own fun parks using levers and closed circuits. Through the understanding of electrical conductivity of different materials, they also set up circuits to supply energy for the motors to operate and to make various amusement rides. The families have completed their fun parks which featured different amusement rides including Ferris wheel, merry-go-round and flying swing. Let’s have a look at their masterpieces!
We hope that all the participated families have enjoyed a good time, which is especially valuable in this very busy city of Hong Kong! We also hope that this workshop had provided opportunity for the young participants to cooperate with others to solve tricky problems and to appreciate others’ works and incoporate the good aspect of others’ works into the own while putting in originality into their own studies and lives as well!
