**Science League Competitions** offer monthly, curriculum-based science contests in **physics**, **chemistry**, **biology**, and **earth science**, delivered and returned by mail through participating schools. Each month, students complete written problem sets that reinforce classroom learning while introducing them to new applications and higher-level thinking in the sciences. Schools receive organized materials and clear instructions, making it easy for teachers to integrate the contests into regular coursework or enrichment time. This program is a strong fit for **high school students** who enjoy problem-solving, want structured practice beyond class assignments, or are considering science-related college majors. Participants gain experience with timed assessments, exposure to a wide range of topics, and the opportunity to track their performance over multiple rounds. For college applications, Science League can: - Demonstrate sustained interest and achievement in STEM - Provide evidence of strong analytical and problem-solving skills - Support applications to science programs, summer research, or advanced coursework Students typically participate through their schools; interested students should speak with a science teacher or department head and can learn more at **[scienceleague.org](https://www.scienceleague.org/)**.
