Other projects like AgeGuess [8] focus on the senior demographics and enable the elderly to upload photos of themselves so the public can guess different ages. Lists of citizen science projects may change. For example, the Old Weather project website indicates that as of January 10, 2015, 51% of the logs were completed. [9]
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. Science projects are done by students ...

Many chemical compounds have a unique numerical identifier assigned by the Chemical Abstracts Service (CAS): its CAS number. There is varying and sometimes inconsistent nomenclature differentiating substances, which include truly non-stoichiometric examples, from chemical compounds, which require the fixed ratios.
