Our Christian homeschooling support group is doing a science fair and both kids are doing projects.
Dd chose to do a project to see if Oreo brand cookies are really the best creme-filled cookie. She got 9 people to volunteer to taste 6 different cookies (Oreo, Oreo sugar-free, Murray sugar-free, Back to Nature, Health Valley, and Newman-O's). The volunteers were not allowed to look at the cookies because most of them had their names on them. They were told to rate each cookie on a scale of 1-10 with 10 being the best. I will post the results after the science fair so as not to give anything away.
Ds originally was going to do an experiment to try to determine which metal rusts the most in water (aluminum, copper, zinc, steel, silver). He was going to use salt-water, distilled water, vinegar and juice. We bought the test tubes online to hold the wire, but then could not find any of the wire at Home Depot except the copper wire.
He is now working on building a trebuchet, which is very similar to a catapult. Ds and dad bought all the materials at Home Depot and spent the afternoon putting the frame together. They seem to have run into some problems, so I am not sure if they will actually be able to continue with this building plan. My view is that the whole process is a learning experience. It would be really cool, though, if they could get it working and be able to lob tennis balls across the yard. |
