Experiment Library
Perform the following experiments and more with the Wireless CO₂ Sensor.
Visit PASCO's Experiment Library to view more activities.
Photosynthesis and Cell Respiration in a Terrarium
In this lab, students will use an oxygen sensor, carbon dioxide sensor, and a temperature sensor to monitor a closed system (terrarium). After conducting their first study, students will be tasked with designing additional investigations...
Photosynthesis
Guide students to measure the change in carbon dioxide (in a closed system) with a carbon dioxide sensor to facilitate an understanding of the relationship between carbon dioxide, respiration, and photosynthesis in plants.
Blockly Extension: Photosynthesis and Carbon Dioxide Emissions
Students use a carbon dioxide sensor and Blockly code to estimate how many actively photosynthesizing spinach leaves it would take to offset the excess carbon dioxide they add to the air from everyday activities.
Cellular Respiration
Students use a carbon dioxide gas sensor to investigate the rate of cellular respiration of germinating seeds.
Decomposition
In this lab, students will investigate the rate of decomposition in different soil and substrate samples.
Respiration of Germinating Seeds
In this lab, students will monitor the respiration rate of germinating seeds in different conditions. Then, they'll analyze their data as it pertains to cellular activity and discuss optimal germination conditions for various...
