The following study shows the manner in which reduction in precipitation caused by climate change impacts plant biodiversity locally. The study also points to things that can be done to live in reciprocity and interdependence with the natural world ie: watering and using fertilizer:

- Teacher reviews study with students using Engaging with Reciprocity and Interdependence Study Summary ppt.
- After reviewing the study students engage in an experiment that mimics the techniques employed by Dr. Paul Grogan and Dr. Lonnie Aarssen to manipulate the amount of rainfall the plants receive. The point is to simulate the effects that a changing climate (droughts and floods), has on plants. See the Engaging with Reciprocity and Interdependence.pdf explaining this activity.
- Earlier in the Bundle in Learning Activity 9: Relational Gardening students were introduced to a three sisters garden and the plants within it. In this experiment, students will use beans. The bean plant is a member of the 3 Sisters Garden, that enriches the soil with nitrogen which benefits both the corn and squash. Please remember that students should treat the beans with love and care while they are engaging in this experiment focused on interdependence. Although students are depleting some plants of the things they need to live, this will help them determine what actions we need to take to help our plant relatives survive in drought-like conditions resulting from climate change. This activity should inspire students to take climate action, so that all plants can continue receiving everything they need to survive. Please encourage students to give thanks to the plants before, during, and after their investigation.
