Science is a strict systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the world. [1] [2] Modern science is typically divided into three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study ...
The earliest of roots of science, which included medicine, can be traced to ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. [11] [12] Their contributions shaped ancient Greek natural philosophy. [13] [11] [12] [14] [15] Ancient Greek philosophers such as Aristotle (384–322 BCE) contributed extensively to the development of ...
Ninth grade. Ninth grade (also 9th grade or grade 9) is the ninth or tenth year of formal or compulsory education in some countries. It is generally part of middle school or secondary school depending on country. Students in ninth grade are usually 14–15 years old, but in some countries are 15–16.
Science is a universal subject that spans the branch of knowledge that examines the structure and behavior of the physical and natural world through observation and experiment. [9] Science education is most commonly broken down into the following three fields: Biology, chemistry, and physics.
Photosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [ 1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Pure physics is a branch of fundamental science (also called basic science). Physics is also called " the fundamental science" because all branches of natural science like chemistry, astronomy, geology, and biology are constrained by laws of physics. [ 60] Similarly, chemistry is often called the central science because of its role in linking ...
e. The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century. The scientific method involves careful observation coupled with rigorous scepticism, because cognitive assumptions can distort the interpretation of the observation.
