Features 25 inquiry based labs covering the fundamental concepts of cell biology, ecology and physiology.

Aquatic Plant Photosynthesis

Lab Summary

Use a dissolved oxygen sensor to understand the amount of oxygen produced through photosynthesis in an aquatic plant in ambient light, bright
light and darkness.

Theory

Guide students to understand the amount of oxygen produced through photosynthesis in an aquatic plant exposed to ambient light, bright light, and darkness.

Method

Students gain experience conducting the following procedures using an aquatic plant in a closed system:

  • Collecting data in ambient light
  • Collecting data in bright light
  • Collecting data in darkness

Sensors / Equipment Used:

PASPORT Dissolved Oxygen Sensor

(PS-2108)

Provides real-time, aqueous oxygen concentration measurements. For use with PASPORT Interfaces.

PASPORT Fast Response Temperature Probe (3 pack)

(PS-2135)

Allows students to see changes in temperature they could never see before. For use with PASPORT and ScienceWorkshop Interfaces.

Photosynthesis Tank

(PS-2521B)

Designed to improve and give more flexibility to measuring dissolved oxygen during photosynthesis.

Magnetic Stirrer

(SE-7700)

A "must-have" piece of lab equipment when doing titration experiments.

Materials Used:

Rubber stopper, #3

Lamp, 100 W (or equivalent)

Cloth, heavy, about 50-cm by 50-cm

Elodea plant (several)

Water, 2 L

The Associated Bundle:

Biology Standard Sensor Bundle

(PS-2925A)

The Biology Standard Sensor Bundle includes a photosynthesis tank and the sensors required to perform 19 of the 24 Lab Activities in the Biology through Inquiry manual.

Interface Required

This experiment may require software and an interface for data collection.
