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
This lesson incorporates techniques and experimental designs used by researchers during the Southern Ocean Diatoms PolarTREC expedition and during post-expedition laboratory analysis. This guided inquiry lesson provides students the opportunity to explore photosynthesis and primary productivity using techniques to measure chlorophyll levels.
Objectives
SWBAT:
1. Use models to predict chlorophyll levels in the global oceans
2. Identify
Soil decomposers, such as some bacteria and fungi, obtain energy needed for life from dead and decomposing plant and animal remains, known as soil organic matter. Soil organic matter is important to local ecosystems because it affects soil structure, regulates soil moisture and temperature, and provides energy and nutrients to soil organisms. It is also important globally, because
