Streamlined objects and organisms, like airfoils, streamliners, cars and dolphins are often aesthetically pleasing to the eye. The Streamline Moderne style, a 1930s and 1940s offshoot of Art Deco, brought flowing lines to architecture and design of the era. The canonical example of a streamlined shape is a chicken egg with the blunt end facing ...
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.
Although a common classroom experiment is often explained this way, [438] Bernoulli's principle only applies within a flow field, and the air above and below the paper is in different flow fields. [439] The paper rises because the air follows the curve of the paper and a curved streamline will develop pressure differences perpendicular to the ...
The best part of the science fair, Recio said, is testing out experiments. Third grade student William Kim admires a winning science fair project on ants at Miller High School on Friday, Jan. 19 ...
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.
Genomic analysis of streamlined organisms have shown that low GC content, low percentage of non-coding DNA, and a low fraction of genes encoding for cytoplasmic membrane proteins, periplasmic proteins, transcriptionally related proteins, and signal transduction pathways are all characteristic of free-living streamlined prokaryotic organisms.
Flow visualization is the art of making flow patterns visible. Most fluids (air, water, etc.) are transparent, thus their flow patterns are invisible to the naked eye without methods to make them this visible.
Experiments might be categorized according to a number of dimensions, depending upon professional norms and standards in different fields of study. In some disciplines (e.g., psychology or political science), a 'true experiment' is a method of social research in which there are two kinds of variables.
