Using the Internet to get data
No matter what you pick up as your science fair project there is likely to be mountains of data on the topic online. So when you sit down to get what data you can use from the internet you need to be careful about where you get that data from.
A number of sites can provide incorrect data that may cause your project more harm than good. So stick to sites that have a good reputation of giving honest and correct information. Some of these sites include Discovery, National Geographic, Popular Science, and Popular Mechanics. All of these sites have reputed writers providing correct and substantiated information on the website.
The websites like Wikipedia or Cheat Sheets need to be checked before the data on them can be used. This is because anybody can write and edit this site. This leave so much more room for incorrect information to creep in. So watch out what data you use from them and try to have it collaborated from a more reliable source if you must use their data.
The internet is the gateway to the highway of information. However like all highways you need to get on the right one to take you to your destination. So pick the information from online sources with care when you sit down to work on your science fair project.
