Measuring the Absorbance of Chlorophyll Solutions at Different Concentrations
In this lesson, students will extract chlorophyll from spinach leaves and make different concentrations following the dilution method. Students will learn to compare the absorbance values obtained at various wavelengths using a spectrophotometer. They will understand that absorbance of a substance is directly proportional to its concentration in a solution. The goal of the lesson is to include investigating the linearity of the relationship and gaining insights into how changes in chlorophyll concentration affect absorbance.

The lesson is adapted from resources created by the Green Drone AZ Project. This is module 1 of 4 featuring focused activities to address real-world environmental challenges within Arizona communities
A lesson to teach students how to collect, organize, interpret data, make inferences, raise awareness, and suggest possible solutions on the water quality of the waterbodies in the state of Arizona.
In this lesson series, students engage with the process of photosynthesis through making observations and processing data through the collection and measurement of gases. Students will integrate data
