PH1LP Teaching Photosynthesis

The PH1LP Photosynthesis Teaching Package has been designed for teaching photosynthesis principles.   The package consists of a sealed leaf chamber with a diffusion based O2 sensor.  This set up allows measurements of accumulation of O2 at saturating levels of CO2 from a leaf placed in the chamber and illuminated with external LED light source. This package has been designed for teaching purposes only.  For research in plant photosynthesis try our Q-Box CO650 Plant CO2 Analysis Package.

The PH1LP Photosynthesis Teaching Package includes everything required to conduct numerous experimental investigations of photosynthetic physiology in a teaching laboratory including full experimental designs. Only the computer and the plant are required! The PH1LP package comes with two sets of manuals, one for the instructor and one for the student. These outline equipment specifications and number of experimental designs and protocols that have been tested by Qubit scientists. With PH1LP Photosynthesis Teaching Package instructors spend minimal time setting up experiments and these are easy to perform by the students.

Teaching principles of photosynthesis in both entry-level undergraduate courses and research-based upper level biology courses. The Instructor’s Manual provides step-by-step protocols for each experiment. It includes suggested variations to make experiments more or less challenging.

Dr. Steven Spilatro of Marietta College, Marietta, Ohio, has put together a great Photosynthesis Investigation Study Guide. It is definitely worth a look!

“We have used both the Photosynthesis and Nitrogenase assay systems and find them robust and easy to use. An excellent feature is that the students can assemble the unit, get it working and then handle the data. This is a great boom from a teaching point of view in that the students feel that they are in control and they learn the real pitfalls in setup and data handling. Qubit’s educational packages are hard to beat. As tools for teaching students the principles of photosynthesis and nitrogen fixation, they are great value!”Testimonial
