A laboratory experiment has been devised to train new graduate trainees in the safe and controlled handling of air-sensitive organometallic reagents using Schlenk lines, high vacuum pumps, liquid nitrogen traps, and cannula transfers. The reaction involves the formation of air-, moisture-, and thermally sensitive 2-pyridyllithium, generated in…

From the streets of clouds to the submarine sand ripples or the striations on the coats of some animals, nature offers many examples of spontaneous patterned structures originating from various instabilities. These patterns can in turn destabilize and show a rich, complex dynamics and possibly end up in disordered behaviours. For over 20 years,…

Although all students need more and better science classes to face the next century's challenges, students gifted in science also need access to dedicated teachers willing to assist their learning progress and encourage their production of original research projects. Integrating the science curriculum would also benefit gifted and other students.…

Students use their preschool experiences to form personal theories about the world and rarely correct misconceptions even when new information is presented. This article describes an elementary science teacher's efforts to help fifth and sixth graders revise personal electricity theories, based on experimentation. There is no simple way to…

This study examined prospective elementary teachers' learning about scientific inquiry in the context of an innovative life science course. Research questions included: (1) What do prospective elementary teachers learn about scientific inquiry within the context of the course? and (2) In what ways do their experiences engaging in science…
