Computer that allows downloading (and uploading in some cases) of files by the use of file transfer protocol (FTP) over the internet. There are over a thousand FTP sites with hundreds of thousands of text, graphics, sound, and video files freely available to anyone. However, a FTP site is not a website because its data cannot be displayed like a webpage. See also anonymous FTP.
Scientific tools for making observations include a microscope, which is a tool used to see very small objects. In your science lab you use a compound microscope to see cells in 2-D, but a scientist can use a scanning electron microscope to view tiny objects in 3-D.
In order to do these investigations, scientists use several tools for experimentation. Basic research equipment includes tools that can be used for measuring lengths, mass, and volume. One of the most basic pieces of equipment used in the measuring of volume is the volumetric flask. Let's discuss the volumetric flask and its use in scientific experiments.
