Abstract

Algae are a diverse group of organisms that influence biogeochemical cycles, feed millions of people, and inspire myriad entrepreneurial ventures. In the classroom, algae are truly an incredible teaching tool that open inroads towards learning in diverse inter-related topics central to any biology curriculum. We have developed a laboratory investigation intended for high school and introductory undergraduate education using consumer water bottles, basic equipment and relatively affordable supplies. In this lab, students integrate various biological concepts and applications through inquiry-based, student-driven research. Teams will apply the basics of photosynthesis and the interplay between two fundamental metabolic modes: cellular respiration and photosynthesis. A number of independent variables such as salinity, nutrients, light, and species are alterable for a myriad of multivariate experimental designs. Students partaking in this lab will gain experience in basic microbiology and plant science skills such as sterile technique, cell counting, and pigment extraction.
