There is a lot of websites out there that will pay you in Bitcoin to complete simple tasks such as click on adverts or watch videos.
The one I recommend is btcclicks.com, this site pays you to view websites. The way this works is that website pay to have their website viewed for a certain amount of time, you then view it and get paid part of the fee.
