University of Arizona

What you'll study

The Natural Sciences degree provides a foundation in core scientific principles and laboratory skills while allowing you to tailor coursework to your interests. Early study typically emphasises foundational courses in biology, general and organic chemistry, physics, calculus and statistics, together with laboratory practice. As you progress you choose upper‑division electives and concentration‑style sequences from departments such as Molecular & Cellular Biology, Ecology & Evolutionary Biology, Chemistry & Biochemistry, Physics, Earth & Planetary Sciences and Mathematics.

• Core topics: general biology, general chemistry, physics, calculus, introductory statistics and scientific communication.
• Typical advanced modules: biochemistry, ecology, genetics, organic chemistry, physical chemistry, thermodynamics, geology, atmospheric science, mathematical modelling and data analysis.
• Practical experience: laboratory courses, fieldwork opportunities in Arizona’s desert and mountain environments, computational labs, and independent research or capstone projects under faculty supervision.
• Electives and interdisciplinary options: environmental science, bioinformatics, remote sensing, science education and courses from other colleges to build double majors or minors.

Entry requirements

Admission to the University of Arizona is based on academic records and preparation. Competitive applicants typically have a strong secondary school transcript with emphasis on mathematics and laboratory sciences. You should have completed courses in algebra, geometry, precalculus or calculus and at least two laboratory sciences (for example, biology and chemistry) where available.

• First‑year applicants: secondary school diploma or equivalent with records of college‑preparatory courses; personal statement and any standardised test information if submitted by choice.
• Transfer applicants: college transcripts demonstrating success in relevant lower‑division science and math courses; an articulated transfer plan is helpful for smooth progression.
• International students: equivalent academic credentials and proof of English proficiency as required by the university.

Career prospects

Graduates with a Natural Sciences degree are prepared for a wide range of paths because of the programme’s flexibility and emphasis on quantitative and laboratory skills. Many students use the degree as preparation for graduate study or professional schools (medicine, dentistry, pharmacy, veterinary medicine), while others enter the workforce directly.

• Research technician or laboratory assistant in academic, government or private sector labs.
• Environmental consultant, conservation scientist or field technician working on resource management and environmental assessment.
• Data analyst or scientific programmer, applying quantitative skills to industry and policy problems.
• Science educator or outreach coordinator following additional teacher certification or community engagement roles.
• Progression to specialised graduate programs (MS/PhD) in biological, chemical, physical or earth sciences, or professional health programmes.

Why study at University of Arizona

The University of Arizona offers access to extensive research facilities, faculty active in diverse scientific fields and hands‑on learning opportunities unique to the region. Students benefit from campus partnerships and interdisciplinary research institutes, opportunities to work with faculty on funded projects, and field sites that include desert, riparian and mountain ecosystems for ecological and geological study.

Small upper‑division classes and mentorship opportunities make it possible to tailor the degree to specific goals—whether preparing for professional school, research or industry—and the university’s career and internship networks help students convert academic experience into practical employment or postgraduate placement.
