         The Research and Related Activities appropriation enables the United States to provide leadership and promote progress across
            the expanding frontiers of scientific and engineering research and education.
         
         The major research program activities of NSF are:
         Biological Sciences.âThis activity supports understanding how complex living systems function and interact with each other and with non-living
            systems, which has direct impacts on issues related to the economy, food, human welfare, and the environment. Research in
            this activity crosses scales from molecules to cells through organisms to ecosystems. This activity's investment portfolio
            includes projects on understanding the fundamental characteristics of biological energy systems; the changing dynamics of
            the biosphere; infrastructure and research resources such as databases, research centers, and observatories; and efforts to
            broaden participation and develop the next generation of biological researchers.
         
         Computer and Information Science and Engineering.âThis activity promotes the progress of computing, communication and information science and engineering research and education,
            and advances the development and use of advanced cyberinfrastructure across the science and engineering research enterprise;
            promotes understanding of the principles and uses of computing and information technology in society; and contributes to universal,
            trustworthy, transparent, and affordable participation in a knowledge-based economy.
         
         Engineering.âResearch supported by this activity aims to increase and strengthen U.S. engineering capability and create a better tomorrow
            by driving discovery, inspiring innovation, enriching education and accelerating access.  
         
         Geosciences.âThis activity is focused on elucidating the many processes that affect the global environment and earth system through research
            in earth, ocean, atmospheric, and geospace sciences. This activity supports basic research, facilities, and associated infrastructure
            that enable an understanding of the causes and implications of climate change, as well as disruptive processes such as earthquakes
            and storms. 
         
         Mathematical and Physical Sciences.âResearch in this activity is directed at increasing understanding of natural laws and phenomena across the astronomical
            sciences, chemistry, materials sciences, mathematical sciences, and physics. Research support is available in multiple modalities
            ranging from multi-user facilities and mid-scale instrumentation to individual investigator awards, from sites for undergraduate
            research experiences to early career faculty development and collaborative and international efforts.
         
         Social, Behavioral, and Economic Sciences.âThis activity supports research, education, and infrastructure in the social, behavioral, cognitive, and economic sciences
            and funds the collection and dissemination of statistics on the science and engineering enterprise.
         
         Office of International Science and Engineering (OISE).âThis activity serves as the focal point of international activities at NSF. In addition to strategic funding and co-funding
            that targets catalytic partnerships and workforce-building international research opportunities, OISE advances NSF's global
            science leadership through extensive interactions with U.S. and global counterpart agencies and organizations.
         
         Office of Polar Programs.âThis activity supports Arctic and Antarctic research and operational science support and other related activities for United
            States polar research programs, including funding to support Federal agencies' logistical needs in the Arctic and Antarctica,
            research collaborations, and related activities supported by the United States Antarctic Program.
         
         Integrative Activities.âThis activity supports innovative, transdisciplinary team science, advanced research infrastructure, use-inspired research,
            and emerging national research priorities. Integrative Activities supports jurisdictional and institutional capacity-building
            programs helping colleges and universities expand their research capacity and improve competitiveness in science and engineering
            research. Additionally, Integrative Activities funding supports activities that expand NSF's capacity to use evidence for
            decision making. This activity provides support for a federally funded Research and Development Center, the Science and Technology
            Policy Institute.  
         
          Technology, Innovation, and Partnerships (TIP).âThis activity advances critical and emerging technologies addressing societal and economic challenges and opportunities;
            accelerates the translation of research results from the lab to market and society; and cultivates new education pathways
            leading to a diverse skilled technical workforce comprising researchers, practitioners, technicians, and entrepreneurs.  TIP
            will accomplish these objectives by catalyzing strategic partnerships that link academia, industry, government, nonprofits,
            civil society, and communities of practice to cultivate innovation ecosystems throughout the U.S., growing regional economies,
            creating the jobs of the future, and enhancing the Nation's long-term competitiveness.
         
         The United States Arctic Research Commission (USARC) is an independent agency, funded through NSF's appropriations. USARC promotes Arctic research and recommends national Arctic
            research policies to guide Federal agencies in developing and implementing their research programs in the Arctic region.

          The STEM Education (EDU) (formerly Education and Human Resources) appropriation funds and manages a comprehensive set of
            programs that further NSF's goals of ensuring a diverse, globally competitive U.S. science, technology, engineering, and mathematics
            (STEM) workforce, as well as a scientifically literate population. To advance those goals, EDU collaborates with other NSF
            research units and Federal agencies, and promotes public-private partnerships. EDU supports research on STEM teaching and
            learning to provide the evidence base for improvements in education at all levels in the STEM disciplines. Supporting development
            and effective implementation of new learning technologies is also a priority. EDU pre-K-12 education-research programs, for
            example, develop and test new instruction materials for students and teachers, which incorporate the latest advances in teaching,
            learning, and education technologies. STEM teacher-education opportunities occur throughout the full continuum, from pre-service
            and in-service, through life-long learning. Research programs at the undergraduate level improve curricula, strengthen laboratory
            courses, enhance faculty effectiveness, and lead education reforms in STEM disciplines. Advanced technological education programs
            strengthen student preparation for the high-technology workforce. Support of graduate-level STEM education primarily includes
            fellowships and traineeships to sustain U.S. leadership in global science and technology. All EDU programs aim to broaden
            participation of groups underrepresented in STEM fields by, for example, improving infrastructure and academic programs at
            minority-serving institutions. EDU activities also include programs supported by H-1B non-immigrant visa fees, which provide
            undergraduate and graduate scholarships in STEM disciplines, improve educational opportunities for students, and provide research
            opportunities for STEM teachers and students.
