The two main branches of physical science are physics and chemistry. Physics primarily deals with forces and the interaction of matter and energy. Chemistry, on the other hand, studies how interaction alters the properties of atoms, molecules and substances.Continue Reading
Physics is the bedrock of all other sciences because it deals with how particles and objects move and transfer force. For example, the study of electromagnetism shows how electrical charges attract opposites and repel similar charges. This fundamental concept governs what types of atoms can undergo chemical reactions. Physics also deals with theoretical concepts such as what happens to objects as they move faster.
Chemistry, meanwhile, deals with the study of how matter's physical properties (the characteristics that make it unique) are affected during interaction with other matter or energy. Chemists work with a wide range of compounds and consult the periodic table of elements to determine what elements will interact and how they will behave. For example, the interaction of hydrogen and oxygen produces a molecule of water. Chemistry makes its way into almost every other scientific discipline and even culinary sciences. Heat, a form of energy, is applied to ingredients and causes the molecules to hopefully rearrange into a digestible and palatable form.Learn more about Thermodynamics
In physical science, mass is a measure of the number of atoms in an object combined with the density of those atoms. The mass of an object determines how that object responds to forces such as gravity and friction. The typical unit of measure for mass is kilograms.Full Answer >
Pure science is science that yields theories and predictions, as in natural sciences such as chemistry, biology, geology and physics, as well as in empirical sciences such as cognitive and certain behavioral sciences. Applied science is a field of science that uses existing knowledge to create practical applications, such as for technology or education.Full Answer >
Although curricula change from one institution to another, the most essential science courses in both high school and entry-level university study are typically biology, chemistry and physics. While biology is loosely described as the study of life, chemistry is the study of the interactions between different types of matter. Physics also concerns the study of matter, but focuses on the entire observable universe.Full Answer >
Basic chemistry, biology and physics terms, such as atom, molecule, mixture, cell and energy, are some common science vocabulary terms an elementary-aged child should know. Other concepts and terms to teach them are the meaning of a hypothesis, the meaning of data and how an experiment works.Full Answer >
