The diary of a globetrotting gnome investigating the variances in gravity around the world. Find out about my experiment and see my results at The Gnome Experiment Follow me or talk to me on Twitter @kerngnome

Interesting experiment to explore the insulating properties of different materials. 

Very interesting.  BTW: Mazur also noted in our conversation that his years of experience on the Physics AP design committee made him less than enthusiastic about AP's. He has data showing that student who got 5s on the Physics AP do worse than other Harvard Physics students who did not take the AP's - a sobering thought.

great multimedia experiment on Joulies coffee warmers. 

cool list of posts detailing experiments in the harvard forest. 

cool site run by two grad students with lots of lab ideas. 

nice description of Millikan's experiment, plus photo of apparatus, and links to original paper. 

Excellent post about science finding its mistakes, using neutrino experiment as an example, and drawing links to climate debate

Interesting experiment using force probe and motion sensor to characterize the energy loss of a rubber band

Fascinating story about experiment that shows tradeoff b/t independent exploration and direct instruction

Many science educators advocate conceptual or qualitative physics, the notion that physics is best taught not by mathematical formulae, but rather through experiments, labs, demonstrations, and visualizations which help students understand physical phenomena conceptually. Consistent with the Physics First curricular movement, this perspective maintains that a deep, fundamental understanding of physics provides a solid basis for future science learning.

post contains very interesting video simulation showing electrons in a semiconductor responding to the applied voltage. 

a great article on with implications for how to better teach the scientific method
