We’ve been having fun putting the new Wireless Dynamics Sensor System through its paces. This new sensor system, which includes a three-axis accelerometer, dual-range force sensor, and altimeter, is perfect for exploring physics topics both in and out of the classroom. Here are just a handful of things we have tried.
This paper introduces the use of a gaseous CO2 sensor and data logging equipment, for a variety of purposes in the school laboratory, including measurements of respiratory and photosynthetic rates of animals, plants and microbes.
Using the average current, the students determine the number of electrons liberated during the reaction. Knowing the mass of copper lost by the anode and the number of electrons liberated, the students are able to determine the number of copper atoms removed from the anode, which they use to determine the mass of a single copper atom.
