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 for photosynthesis and cellular respiration.

Featured Equipment

Wireless Oxygen Gas Sensor

The Wireless Oxygen Gas Sensor measures gaseous O₂ concentration as well as humidity and air temperature for a range of biology, environmental science, and physiology activities.

Wireless CO₂ Sensor

Wireless CO₂ Sensor

The Wireless CO₂ Sensor measures carbon dioxide gas levels and wirelessly streams data to your computers, tablets, and smartphones.

Temperature Sensor

Wireless Temperature Sensor

The Wireless Temperature Sensor is a general-purpose sensor found in many science labs. With a rugged, waterproof design, and long-lasting battery, students can spend more time collecting data and less time dealing with equipment.


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

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
