This lesson investigates the correlation between the rate of cellular respiration and metabolic rate of Weddell seal pups. Students will collect data of their personal oxygen consumption rate at rest and during exercise, and evaluate how collecting oxygen data can be used to calculate metabolic rate. Students will comprehend that heat is a product of the reaction of cellular
This lesson investigates the effects of different insulators (fur and blubber) on maintaining the body temperature of polar animals. Water balloons filled with warm water simulate the marine mammal. The blubber insulator will be simulated by covering the balloon in vegetable shortening. The fur insulator will be simulated by placing another balloon over the “marine mammal” and adding an
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 individually weigh a random sample of pennies. The data will be graphed to look for patterns, then explanations will be sought to explain these patterns. Some of the key ideas are using graphical representations of data to help identify patterns. This is a key concept in all sciences, including in the IceCube Neutrino Observatory - data
