Weather in a Terrarium

Lab Summary

Use a weather sensor and light sensor in a terrarium to conduct and design an investigation of weather, using this closed system to help identify independent variables, dependent variables, and controlled variables.

Theory

Students demonstrate that a terrarium, a closed system, is an excellent tool for conducting environmental studies such as weather investigations. As part of this process, students:

  • Learn to use this closed system to change one variable at a time, control other variables, and monitor multiple variables.
  • Design additional investigations of weather using the terrarium.

Method

Students gain experience conducting the following procedures:

  • Designing controlled investigations.
  • Determining the effect of a plant on the weather inside a terrarium.
  • Using sensor technology to monitor independent and dependent experimental variables.

Sensors / Equipment Used:

PASPORT Light Sensor

(PS-2106A)

Features a wide measurable range by offering three light ranges accommodating various different measurement situations. For use with PASPORT Interfaces.

PASPORT 6-in-1 Weather Sensor

(PS-2154A)

Measures barometric pressure, relative altitude, absolute and relative humidity, dew point, and temperature. For use with PASPORT Interfaces.

PASPORT Sensor Extension Cable

(PS-2500)

Allows an additional two meter length extension on all PASPORT sensors.

EcoChamber

(ME-6667)

A single acrylic chamber designed to integrate sensors for controlled-environment experiments such as fermentation and plant or cricket respiration.

Materials Used:

Fast-growing, small, potted plant 
Strong incandescent or full spectrum fluorescent light source
