Learning about waves can have its ups and downs, but a demo-packed tool kit has the class "standing" for more! Learners gain experience with several different wave types, organizing observations and data, and wave...

Dive into the mystery of sound waves!  Scholars brainstorm questions about how sound travels and why different items make different sounds. They then conduct experiments to answer their questions.

Students are introduced to the topic of electromagnetic induction. In groups, they describe ways in which the magnetic flux can change and discuss emf and current. They use different scientists laws and apply it to various scenerios in a...

Attracted class members to an activity-packed journey through the science behind the invisible forces at work all around us. From jump rope generators to junkyard wars, there's never a dull moment when eighth grade physics scholars...

This page and the three pages which follow discuss how X-ray technology can be used to produce an image of the human body. Discussion is understandable and highly intriguing. Several interactive animations allow the visitor to explore...

Students are presented with a challenge question concerning color blindness and asked to use engineering principles to design devices to help people who are color blind. Using the legacy cycle as a model, this unit is comprised of five...
