Here are some websites that have information on science fairs, which might
give you good general science project information:
http://www.ipl.org/youth/projectguide/
http://www.exploratorium.edu/ls/pathfinders/scifairs/index.html
http://school.discovery.com/sciencefaircentral/
http://www.scifair.org/
There are others in this vein as well if you want to do your own search.
Specific information about the doorbell can be found at
http://www.howstuffworks.com/doorbell3.htm
http://www.exploratorium.edu/snacks/magnetic_suction.html
and others. You can always also check with your local librarian who
should be able to help you find further resources.
