In preparation for students receiving a course of applications in biology, we encourage learners who will become teachers in the future by teaching the science of life (known as biology) through which the student can learn the foundations of science and its technological, applied and medical importance at all levels. The course also aims to introduce students to the method of that science and different protocols and providing them with the tools they need to make decisions towards the application of science. It seems logical that students who use this course will not be scientists but rather successful teachers to lay the foundations of science and put forward the mechanisms of scientific thinking and use it to become successful teachers. Therefore, they definitely need to be familiar with practical concepts and basic biological principles. We confirm through the course that the science of life, is not a set of facts, but rather an ongoing endeavor by a diverse community of people. We confirm this point by describing and providing stories and principles ideas of scientists who do so. We will explain not only what is known, but also how it was discovered and how our understanding has changed over time. We will focus on the theories that contributed to the advancement of this science and its interconnectedness with other sciences in a period of time that became important to link between sciences as an approach followed by the advanced world in education.
