Hello readers!!! Today I am going to tell you about a favorite website related to my career, specifically, I am going to tell you about " Phet ". Phet is a website developed by the University of Colorado Buldier and is completely free. It is a simulator website with multiple simulations on Physics, Biology, Chemistry and Mathematics. On the page you can search for simulations by one of the areas mentioned or by the concept to be studied. In Physics you can find simulations on circuits, states of matter, kinematics, among others. My favorite simulation is on circuits. When I must teach a Physics class, I visit this website looking for a simulation according to the contents I teach. This simulation helps students to understand the Physics concepts studied in the class. Also, these simulations are very easy to perform, with an intuitive and user-friendly interface. Thanks for reading.
