it has occurred since 1991. More than 5,000 students across 600 schools participated in PJAS (compared to 14 schools in 1934) with more than 3,000 students presenting their scientific research at the 2020 State Meeting. The 2020 State Meeting was cancelled due to the COVID-19 pandemic. The 2021 State Meeting was held in a virtual format due to the lasting effects of the pandemic, requiring students to pre-recorded their presentations. PJAS participated as a sponsor/donor to the National Association of Academies of Science and the American Junior Academy of Sciences (AJAS) 2022 Conference. Projects PJAS projects fall under four main groups: Science, Mathematics, Computer Science, or Engineering projects. Each of these categories use their own individualized rubric. Science Projects Consists of projects in the following categories: Behavioral Psychology (BEH) – The systematic investigation of mental phenomena of human and other animals, especially those associated with consciousness, behavior and the problems of adjustment to the environment. Biology (BIO) – This category is for the life science projects which do not fall into any other category. This includes, but is not limited to, projects involving human medicine and dentistry. Biochemistry (BC) – The study of chemistry within living organisms with emphasis of the process. Botany (BOT) – The study of plants. Chemistry (CHM) – The study of the composition of matter and how matter can change. Earth and Space (ES) – The study of the earth and extraterrestrial bodies and the processes affecting them. This includes, but is not limited to projects involving geology, oceanography, meteorology and astronomy. Ecology (ECO) – The study of the interactions and relationships of living things to their abiotic environment and to each other. This includes, but is not limited to projects involving pollution, environmental alterations, and ecosystem analysis. Microbiology (MIC) – The study of microorganisms, which are defined as any microscopic organism that comprises either a single cell (unicellular) or cell cluster. This includes eukaryotes such as fungi and protists, and bacteria and prokaryotes. Physics (PHY) – The study of matter and motion. This includes, but is not limited to projects involving the traditional subsets of physics (i.e. statics, dynamics, optics, acoustics, heat and electricity) and applied physics (i.e. mechanical, electrical, and civil engineering). Zoology (ZOO) – The study of animals. This includes, but is not limited to projects involving animal physiology, animal anatomy, animal pathology, and animal genetics. Mathematics Projects Consists of projects heavily focused
