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
Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
Overview
A focus of the PolarTREC Southern Ocean Diatoms expedition was to collect water samples and physical profile data using oceanographic technology. Oceanographers rely on the real-time data transferred from the water column to the ship-based computers using a CTD sensor. The CTD measures conductivity (salinity), temperature and depth
Students will learn the basics of calorimetry, energetics and respiration as they pertain to their own bodies and to those of other species, including arctic animals.
Objective
Students will learn about respiration, calorimetry and the energetic needs of various species including their own. Students will compare food intake to daily energy consumption and consider the consequences of
Students will conduct quantitative and qualitative observations on living organisms. By recording careful measurements, making and testing various hypotheses, on super mealworms, students will gain some understanding of how wildlife researchers conduct their studies.
Objective
Students learn to take measurements on living organisms and use those measurements to consider the health of the organisms.
Dividing the class into Little auks and predators, students complete survival game for several seasons. After tallying up total volume of food collected, survival rates of the chicks can be graphed and analyzed.
Objective
Students will be able to experience the hazards that Little auks must avoid in order to survive. Students will understand the value of
