Although discussions about the possibility of online education in elementary and high school in Brazil have entered the wake of the theoretical debate, there is still great resistance. However, the pandemic context brought no alternatives, leading thousands of students to social isolation for more than a year. This context caused elementary and high school teachers to adapt to new technologies, thus demonstrating the need to prepare to work in remote learning teaching. The guide question of this material was: How can life science teachers prepare and what basic tools should they know to prepare their online classes? Thus, the general objective was to carry out indications that teachers should know to prepare their online classes. The methodology adopted was exploratory through literature review. The main indications were that teachers need to seek diversified content in the preparation of classes to adopt motivation strategies with their students, adopting care with the issue of language, audio and light in the production of classes. Finally, it will be up to the teacher to recognize the various tools and resources such as: Youtube, Instagram, Movies, Games, and other subsidies, so that there is an approximation between the teaching of biology and the reality of the student.
