Im looking for Science Fair ideas, and I heard that you can find the date of when a painting is created to know if its fraud or not.

You could use carbon dating, a method of dating objects which measures carbon generated from once living matter taking in carbon dioxide from the air, but that would be too complicated for a science fair.
Over time, the paints used have changed. You could do chemical analysis of the paint --> http://www.cyberlipid.org/perox/oxid0011.htm
You can use x-rays to see below the paint. http://www.mystudios.com/artists-mind/volume-04-2002.html. Maybe a Dr. or Dentist could help?
You can use microscopic analysis to see things about the materials used... --> http://www.computer.org/portal/site/cise/menuitem.519414668cc18778161489108bcd45f3/index.jsp?&pName=cise_level1&path=cise/freebies&file=news.xml&xsl=article.xsl&

The easiest way is using spectral analysis on the pain itself. Paint has changed dramatically and things like titanium white dates paintings. also you can see if there is a painting underneath which adds to its authenticity

An easy way is to use ultraviolet light. For example titanium white will fluoresce under UV light and it was developed much later than earlier white pigments.
Here are some articles about it:

Carbon dating is the easiest way of course since all things have some amount of carbon in them
