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.
The journal assignment involves students in current science research. Through the teacher’s journals, they will learn about how the research teams work together, design their research, tools that are needed and how they live and work in an extreme environment.
Objective
Students will be able to:
1. Understand how scientific research is conducted in an extreme environment
Working in groups, students will use common materials to create layers of snow and ice representing thousands of years of stratification. Groups will exchange their ice layers and extract core samples to analyze them.
Objective
Notice the phenomenon of stratification.
Notice that layers can tell a story of change over time.
