I really enjoyed the We All Scream for Ice Cream webquest. It's so interesting to learn about the world around you and children will remember that project every time they eat ice cream. It teaches them patience, it connects them to their food processes, it teaches them math and science, and it's delicious. I remember making paper as a third grader with my teacher. We measured water and ripped up newspaper and made a pulp then we stuck it back together on cheesecloth and let it dry and it turned into paper. So cool!
I didn't really care for the Where is My Hero project. I feel like it could become to political for elementary students and also I think it runs the risk of children admiring people that are actually bad influences on them. Then it puts the teacher in a awkward spot on deciding what's appropriate. I also think the project feels more like writing a research paper which is not fun for an elementary school child.
