The theme of today is the wind turbine. The wind turbine model transferred the wind energy generated by a fan to electrical energy stored in the power meter. The experiment is a very good mimic to the real wind turbines used in real world. The students finished the model building part smoothly, and then they all conducted and finished the experiment. During which I explained the STEM information, which is the power equals to voltage multiplies current.
Most of the student cannot perform decimal multiplications, thus the experiments were simplified to observe and record joules instead of watt calculations. One extra part to use the generated electoral power was also added to the class, which deepened their understandings of the Power Meter usage. All students finished the experiments and filled the lab sheets. They love the challenging project.
