Along with the COVID-19 pandemic, universities in Turkey as well as all over the world have started to carry out their education activities with the distance education method. In this case, many difficulties were encountered in the application of the Biology course, which is one of the applied courses carried out in the laboratory. Virtual laboratory applications can be preferred especially in teaching abstract subjects that are difficult to understand such as respiration. The teacher can write the process steps and theory related to the experiment to be designed, and the students can follow these process steps and perform the experiment in an interactive way. In this way, students can have a real-like laboratory experience by following the experimental procedure with laboratory materials step by step.
