BUILD YOUR OWN COMET
http://www.noao.edu/education/igcomet/igcomet.html
This report describes how to build a model of the outer 300 km (180 miles) of the Earth that can be used to develop a better understanding of the principal features of plate tectonics.

Students will use a CO2 Gas Sensor to measure the amount of CO2 in a classroom. Measurements will be taken during a class period and students will observe the changing CO2 levels.

Students will use a Sound Level Sensor to measure the intensity of various sound sources. Measurements will be taken during different times of the day and at different locations and students will observe the changing levels.

Students will use a pair of Temperature Sensors to investigate convection currents in a water tank.

Students will measure the conductivity of water samples, both before and after being mixed with soil samples, to determine if water "runoff" from soil is more or less likely to conduct electricity

In this experiment, we will use the Humidity/Temp/Dew Point Sensor to measure air temperature, dew point and relative humidity in a plant terrarium.

Students will measure the turbidity (cloudiness) of water samples from locations near their campus.

In this experiment, we will use the Barometer Sensor to measure atmospheric pressure over a 24-hour period. Students can then hypothesize reasons for any changes that occur.
