This contains all the parts needed to achieve a stethograph and a potometer.  The stethograph is described in the resources of the Pressure (Difference 1 KPa) sensor page.  The potometer is achieved with a simple tube system which bathes the end of a large leaf in water and measures the fall in pressure of an air pocket adjacent to this water. Also included in the accessory pack for the 1KPa Sensor is a Spirometer attachment.
