is it that hamsters exercise at the same time every day, even
when living in round-the-clock darkness? That's one of the questions
the Center for Biological
Timing helps budding young scientists answer with its online
science experiment web site, which outlines a variety of science-related
activities both for middle schoolers and the kindergarten-through-fourth-grade
set. Researchers at the center, supported by the National Science
Foundation and directed by Vice President for Research and Public
Service Gene D. Block, investigate various "biological clocks"
and their effects.
