Science Buddies is a website, [2] recommended by educational organizations such as the ALA [3] and the SciLinks program of the National Science Teachers Association (NSTA). [4] All resources and tools on the Science Buddies website are available free to students and teachers. Science Buddies uses an underwriting model of sponsorship (similar to ...
[4] [5] An emerging branch of Citizen Science are Community Mapping projects that utilize smartphone and tablet technology. For example, TurtleSAT [6] is a community mapping project that is mapping freshwater turtle deaths throughout Australia. This list of citizen science projects involves projects that engage all age groups.
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 strong interaction, or strong nuclear force, is the most complicated interaction, mainly because of the way it varies with distance. The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 10 −15 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm. At ...
The above experiments search for a fifth force that is, like gravity, independent of the composition of an object, so all objects experience the force in proportion to their masses. Forces that depend on the composition of an object can be very sensitively tested by torsion balance experiments of a type invented by Loránd Eötvös.
Forces of flight on a powered aircraft in unaccelerated level flight. Understanding the motion of air around an object (often called a flow field) enables the calculation of forces and moments acting on the object. In many aerodynamics problems, the forces of interest are the fundamental forces of flight: lift, drag, thrust, and weight. Of ...
In the first fourteen SSEP flight opportunities, 86,800 students in grades 5 through 16 (senior undergraduate in the U.S. higher education system) participated in experiment design and proposal writing. Of 18,759 proposals received, a total of 240 experiments were selected for flight, with one from each community participating in each flight ...
[4] [5] In 1947, Arthur Roderick Collar defined aeroelasticity as "the study of the mutual interaction that takes place within the triangle of the inertial, elastic, and aerodynamic forces acting on structural members exposed to an airstream, and the influence of this study on design". [6]
