The Chemistry Extension Lab Station includes four wireless sensors and additional lab components that complement the set of sensors and components found in the Chemistry Starter Lab Station (EC-6362). Together, the sensors from the Chemistry Starter and Extension Lab Stations comprise the sensors to perform many of the lab investigations inside PASCO’s Essential Chemistry Student Lab Manual and Advanced Chemistry Through Inquiry Teacher Guide. A storage slot for each sensor in the Chemistry Extension Lab Station is available in the Gratnells storage tray that comes with the Chemistry Starter Lab Station.
