pressure & temperature

Pressure & temperature How pressure changes with temperature can be monitored using sensors. A graph of pressure against temperature can be plotted as it happens. After the experiment, the scale of the axis can...

osmosis

A pressure sensor can be used to monitor the progress of osmosis. In this experiment a dialysis bag containing sucrose solution is placed in a beaker of water. Over a period of time, water...

a data logger is a scientist’s camera

data loggers – the scientist’s camera! There is a rich world of data waiting to be collected. Take an accelerometer with you on a theme park roller coaster or if that’s too sad, take...

pressure & temperature

The pressure in a sealed container changes with temperature. These changes can be monitored using sensors attached to the computer. A graph of pressure against temperature can be plotted as the changes occur. After...

monitor breathing

Is your breathing steady while you sit restfully? How does it change when you talk? How does it change when you exercise? How quickly do you recover after exercise? To find out you can...

plant transpiration using a pressure sensor

Transpiration and a pressure sensor A sensitive barometric pressure sensor can be used to demonstrate transpiration. The picture here shows a low pressure sensor (as it was called) with a tube sealed onto the...

pressure sensor

A surprisingly useful sensor which is usually on the expensive side. They come in various ranges and while no single range handles all uses you can settle on a mid course. Some measure air...
