position or angle sensor
This sensor allows superb and easy to do investigations into the swing of a pendulum leading on to studies of harmonic motion and damping. (See several examples nearby). It allows you to record the period of every swing of a pendulum, instead of timing ten and dividing by ten. This in turn strikes us as more convincing. There are ways to do this experiment which ensure that your graph axis are centre screen and also that sets of pendulum swings will all start at the same part of a swing. These are features to look for in the software. Other reported uses include recording the rise of bread dough or as a lever arm responding to movement. You can use it to measure plant growth over time, though it is worth exploring ways to set this up as a lot of plant growth is due to the slip of the thread holding the plant!
My rating was **** / ++
I’ve rated these sensors but your assessment will be different. I give * to **** for the sensor’s intrigue, interest, and learning potential. I give from + to ++++ for how often a science department might use it.
