An Experiential Journey from Static to Dynamic Electricity and Electromagnetism<\/strong><\/h3>\n

Several thousand years ago, a small child discovers a yellowish stone while playing. The child is so impressed by its color and shine that he runs to show it to everyone. To better highlight the color of the stone, the child rubs it against the fabric of his clothing and places it on a rock for all to see. However, when he brings it closer to the rock, all the dust particles around stick to it. This was the first encounter with static electricity. The stone\u2026 was amber, now known for its electrostatic properties. But how is this unknown, invisible phenomenon of static electricity created? Is it really something invisible, or can we see it in some way? Can we perhaps trap it in a jar or a container and use it whenever we decide? Does it contain some form of energy, or is it energy itself? Can it be converted into another form of energy? Answers to these questions were provided by later scientists after many years of painstaking experiments. We then arrive at the era of Edison, who not only managed to store this energy but also convert it into light. On October 21, 1879, Edison\u2019s light bulb worked for a full 13.5 hours. On New Year\u2019s Eve of that same year, Christie Street was illuminated with light bulbs all night long. The miracle had happened. However, the big question now was different: Could this \u201celectricity\u201d be transported even further? Could it light up all of America? Is dynamic electricity, as it is called, capable of traveling as far as we want? An assistant of Edison, Nikola Tesla, believes that Edison is wrong. A different type of electricity must be created, one that would have no losses during transmission over long distances. The war of currents had just begun. For many years, the two scientists \u201cquarreled\u201d over who would provide the correct solution. Ultimately, Tesla\u2019s electrical current, now known to all of us as alternating current, prevailed over direct current. Nikola Tesla died alone on January 7, 1943, in a hotel room. The exciting journey of electricity unfolds through experiential workshops, following the path from the first encounter with static electricity to the modern transmission of electric current hundreds of kilometers away, whether above ground, underground, or underwater. The program \u201cSkills Workshops _ Electricity\u201d consists of 9 activities, each lasting 45 minutes. In an extension of the experiential workshops, measurement with the microcontroller Micro:bit is introduced, so that children can have their first encounter with the measurement precision needed for modern experiments.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Objectives of the Program<\/strong><\/h3>\n

Understanding the\u00a0Basic Principles<\/strong>: Students should comprehend the fundamental principles governing static electricity, dynamic electricity, and electromagnetism. This includes understanding their laws and the interactions between electric charges. Understanding\u00a0Modern Applications of Electricity<\/strong>: Students will develop the ability to identify the application of the basic properties of static and dynamic electricity in everyday life, technology, and science. Acquisition of Skills in\u00a0Using Digital Tools<\/strong>: Students will learn to conduct digital measurements of physical quantities and represent them in graphical form. They will also learn to program microcontrollers to create measurement systems. Research Skills:<\/strong>\u00a0Students should develop research skills related to the subject matter. This includes the ability to design and conduct experiments, collect and analyze data, and draw conclusions based on the results. Collaborative Work and Communication<\/strong>: Students should be able to work in teams and collaborate for optimal outcomes in their experiments. Deepening Understanding of Difficult and Abstract Concepts<\/strong>: Concepts such as charge, flow of charge, and resistance will come alive in playful ways before the students\u2019 eyes for better understanding.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
