Although the Drop Counter was developed to record drops during titration, attaching the Luer-lock stopcock to the outlet of a chromatography column adapts it for use as an inexpensive fraction collector for column chromatography.
Ron Bowerman knows how to motivate students—competition. In his physics class, students compete for a simulated high stakes contract with an airline. Physics and engineering skills are put to the test as students work in engineering teams that try to design the lightest and strongest wing spar for an airplane.
The FIRST LEGO® League Team from Reston, VA recently took part in the High Altitude LEGO Extravaganza (HALE) balloon launch. Their payload included a LEGO NXT Robotics System with a Vernier NXT Adapter and two Vernier sensors—a UVB Sensor and a Surface Temperature Sensor.
Have you ever wondered about how much outlier points influence the curve fits you do in software like Logger Pro? Or, how much you can rely on measures like the slope uncertainty or the correlation coefficient as a judge of how good a line fits your data?
Is the heat given off by 500 people enough to change the temperature inside a large auditorium? How does the temperature and salinity of a tide pool compare to that of the nearby ocean water? These were just two of the questions posed to about 250 students from 52 countries who gathered in Cape Town, South Africa, this summer for the GLOBE Learning Expedition (GLE). And of course, Vernier equipment was used to investigate the answers to those questions.
