A science teacher or specialized high school teacher educates high school students to prepare them for postsecondary school or the workforce. Their main duties include planning and instructing lessons, assessing and supporting students' strengths and weaknesses, and adapting and enforcing classroom policies. Effective Science teachers know how to use their students' prior experiences to help students align with the real-world issues they face in their everyday lives. Science encourages students to learn according to their own interests.
