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 quickly, 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. All students finished the experiments and filled the lab sheets. They love the challenging project.
