Teach both photosynthesis and cellular respiration simultaneously in a single lab — with algae beads! The Photosynthesis and Cellular Respiration Kit for General Biology is a fun, easy-to-use, and more reliable alternative to the leaf disk and microrespirometer labs. The simple algae bead system in this kit is a great tool for students to learn experimental design and can help you dispel the common student misconception that plants only do photosynthesis.

Features and Benefits

The Photosynthesis and Cellular Respiration Kit for General Biology was designed with Next Generation Science Standards* (NGSS) experts and teachers to help you meet the NGSS requirements for general biology. Students will engage in 3-dimensional learning as they explore both energy processes.

  • Lessons and content designed for the NGSS
  • All the consumables and reagents for 3 classes of 8 student workstations (24 total workstations)
  • Reusable algae beads for multiple class periods
  • Instructor’s Manual with lesson plans, graphical preparation instructions, and thorough troubleshooting information

This kit contains curriculum and sufficient materials for 3 classes of 8 student work stations (24 total workstations)

  • Day 1: Observing a hands-on phenomenon — to spark curiosity and to ask questions
  • Day 2: Planning an experiment with algae beads — to lead students through asking scientific questions and designing experiments
  • Days 3–4: Collecting data and constructing scientific explanations — to involve students in authentic scientific inquiry
  • Day 4: Answering post lab questions — to apply gained knowledge in new scenarios

How it Works

The algae beads (microalgae immobilized in alginate) included in this kit are easy to handle and can be used for multiple experiments. The algae beads are incubated in a CO2 indicator solution that is sensitive to changes in pH caused by gaseous CO2 dissolving in water to form carbonic acid according to this equilibrium:

CO2 + H2O ⇔ H2CO3 ⇔ HCO3 + H+

The experimental setup of the Photosynthesis and Cellular Respiration Kit allows students to track photosynthesis by CO2 consumption and cellular respiration by CO2 production.
