Improve your understanding of our most basic building blocks:
molecules and atoms.
This site covers off the subjects of biology, molecular biology, physics/chemistry
and systems. It is designed to help students understand the interactions of
atoms and molecules.
You'll find information on a range of topics from atomic structure and
strong chemical bonds to "mutations: changing the genetic code." Each topic
includes an interactive activity to test your knowledge of the subject.
Activities must be downloaded and require certain software.
Activities are largely derived from the Concord Consortium, sponsored by
the National Science Foundation. http://www.molo.concord.org/
