I just got off the phone with my daughter. Her son had a last-minute crisis with a project due - you could see this coming - tomorrow!
Fortunately, it was a science research project, and I was able to clarify the terms that were causing confusion - habitat, community, niche, and population.
That's why I seldom assign projects. It seems to cause more work for the parents than for the kids. When I do hand out projects, I try to assign them so there are points where I check the progress, and can assist in re-directing effort in more productive channels. One of the few I think worthy are science fair projects. But, only if I have the kids bring in their work-in-progress to make sure they stay on task.
