In this engineering science fair project, students will determine the most effective method for quickly raising the temperature of a liquid in a tank. The Science Buddies project ideas are set up consistently beginning with an abstract,...

This activity will show students how objects change size when heated and cooled. Students will observe a metal tube have expansion and contraction.

Over more than a century, the global average temperature warmed 1.5F (0.8C). Learn the science of why this has happened, and what the future holds.
