Day and Night Temperature Changes
A long 48-hour recording of temperature and light levels, with the
Labdisc located on the window shelf:
•
Sensors selected: Light, ambient temperature
•
Sampling rate: 1/min
•
Amount of samples: 1000
•
Experiment duration: 48 hours
•
Communication: Offline, data downloaded at recording’s end
•
Data Analysis: Use the Markers to show min/max. values
Walk in the Park
Micro climate activity. Comparing temperature and Relative humidity at
a city cross-road and park:
•
Sensors selected: External temperature, relative humidity, GPS
•
Sampling rate: 1/sec
•
Amount of samples: 1000
•
Experiment duration: 15 minutes
•
Communication: Offline, data downloaded at recording’s end
•
Data Analysis: Temp./humidity changes in GlobiLab map view
Free Fall
A classic activity for Newton’s 2nd Law. Measuring the free fall
acceleration of a ping pong ball bouncing on a wooden surface, with the
distance sensor located 1.5 m above it:
•
Sensors selected: Distance
•
Sampling rate: 25/sec
•
Amount of samples: 1000
•
Experiment duration: Seconds
•
Communication: Online, preferably via wireless Bluetooth
•
Data Analysis: Use Markers and Crop functions to focus on the
ball bounces. Then use quadric regression on a single bounce, to
get the bounce equation and extract the free fall acceleration.
