In biology class, climate change is relevant because of its impact on biodiversity. While the subject of climate change should be taught in science classes, problems with teaching it involve preconceived ideas that can create barriers. Instruction is also hindered by a lack of materials that support direct observation by students in both rural and urban areas. An inquiry-based approach incorporating phenology offers a possible solution to the problem, giving students the ability to observe climate change firsthand. Phenology is the practice of observing flora or fauna over a time period within a geographic area and recording seasonal changes. The data can be uploaded into the National Phenology Network for study purposes. This website also provides materials, lesson plans, and instructions for observing seasonal changes and connecting them to climate change, which can then be correlated to impacts on biodiversity. The Department of Natural Resources National Wildlife Federation also has material that can help the instructional process. When students are involved in direct observational activities, climate change moves from an abstract concept to a concrete phenomenon. Their new knowledge can empower students to try and make a difference at a local level.
