Science Bug is a site for elementary science learners. It is designed to get kids (and especially girls and minority students) excited about science. Beyond this goal the site also provides elementary students with an understanding of scientists and the work they do.
The site contains several science investigations supported by video clips, assessment, and recording sheets. Investigations are aligned to National Science Standards.
Applications for Science Teachers: Another user-friendly resource for teachers of elementary science. The investigations are balanced between life, physical, and Earth science.
