The Middle School Science Extension Lab Station includes four wireless sensors that complement the set of sensors found in the Middle School Science Starter Lab Station (PS-3312). Together, the sensors from the Middle School Science Starter and Extension Lab Stations comprise the sensors to perform many of the lab investigations inside PASCO’s Essential Middle School Science Lab Manual. A storage slot for each sensor in the Middle School Science Extension Lab Station is available in the Gratnells storage tray that comes with the Middle School Science Starter Lab Station.
