A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
In science and research, an attribute is a quality of an object (person, thing, etc.). [1] Attributes are closely related to variables. A variable is a logical set of attributes. [1] Variables can "vary" – for example, be high or low. [1]
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
The Expo featured interactive hands-on science activities presented by over 550 U.S. science and engineering organizations. [1] 125 universities/research institutes, 125 professional science societies, 50 government agencies, 30 high tech and life science companies and 150 informal science outreach organizations participated in the festival.
The fair is fed by 28 regional science fairs, each of which is allocated a number of projects based on prior history of producing winning entries. The allocation in 2009 was 908 projects, an average of 24.7 projects per million population. [1] Awards are given in several categories at both junior (grades 6–8) and senior (grades 8–12) levels.
