Scientists are studying the effect of climate change on vegetation in the Alaskan tundra. In this activity, students will analyze data collected from control plots and plots with Open Top Chambers (OTC's) over them. An open-top chamber is like a tiny greenhouse that increases the temperature in a vegetation plot an average of 2-3 degrees, simulating the effects of
After spending 5 weeks in the Arctic learning about tundra vegetation and phenology, Alejandra Martinez wanted to have her students observe the growth of plants in their school. In this lesson, students will grow plants in multiple locations and track their growth to compare their phenology.
Objectives
Students will learn what phenology is and make observations about plant growth
In this investigation, students will measure production of CO2 from surface water and consider the role of surface waters in the global carbon cycle and climate change. They will gather data on using Vernier CO2 sensors. This lesson presents a wonderful opportunity for student-designed experiments.
This is a good lesson to get students thinking about the complexity of the systems involved in providing our society with energy, the consequences of energy use and efficiency. Students are encouraged to explore the data sets on their own, ask their own questions about energy use and present their findings to each other.
Students will explore the concept of albedo and how it relates to melting ice and climate change. This is a hands-on activity where students measure the reflectivity of various surfaces as a model for how light interacts with different parts of the Earth’s surface. This is adapted from lessons created by Jamie Esler and SERC earthlabs.
Learning about feedback mechanisms is an important part of understanding how climate change will play out in the near and long term. Students are also exposed to the idea that scientists create simple models of complex climate systems and that feedback mechanisms play a crucial role in climate modeling.
