Photosynthesis Unit-- Photosynthesis is concept few students being taught by traditional methods can understand or crasp let along appreciate it's vital role for almost all of life on Earth.
The goal of our unit on Photosynthesis is to have the students practice the nature of science through the process of developing a theory and model of how an alien species is obtaining its energy. Since the mechanism for the aliens is analogous to how plants obtain energy, the alien scenario is providing a hook, based on inquiry to further study the process of photosynthesis. The students will move from their alien scenarios to plants on earth and incorporate this “new” knowledge into the revision of their alien models. The major concepts are the conversion of energy, how photosynthesis occurs, and the importance of the products and waste products of photosynthesis for all life.
Students are directed to focus on the alien data concerning light, O2, and glucose as a possible input or output. Students investigate the data supporting or refuting these elements as possible sources of energy. The chart and their models should be worked on to completion.
This particular lesson has students explore what the bubbles being release from a samples of skin are. They do this by analyzing the gas using Vernier probes. This is activity 3 of Lesson 2.2 from our backbone
