The "Forty Electronic Challenges" is a "discovery learning" and socio-constructivist science activity that has become rather popular in Canada. The article recalls its emergence and development. It discusses its theoretical underpinnings and how it fits into the existing literature. It then gives educators all the guidelines…

Below the surface of the ocean, currents, eddies, and other physical processes redistribute energy and biologically important elements. Measuring this transport can be challenging, and scientists must address a wide spectrum of oceanographic and engineering concepts when designing instruments to observe these processes. In this activity,…

Students have several misconceptions about thermodynamics. However, an understanding of basic concepts in this branch of physics remains fundamental to explain thermal phenomena. The purpose of this activity was to extend students' conceptual understanding of heat, temperature, energy, and thermal insulators and conductors. Two groups of students…
