Heads and Tails: Investigating the Effects of Plant Extracts on Planaria Regeneration Cells, Regeneration and Model Organisms
Overview
This lesson is designed to introduce students to the concepts of stem cells and regeneration using planaria as a model organism. Students will learn how neuroscience research promotes health and leads to understanding and therapies. Additionally, students will discuss ways to do such research ethically. In the lab portion, students will explore how the plant extracts they made previously in the Infusions & Decoctions: Preparing Plant Extracts lesson affect planaria regeneration.
