Students will understand how the increasing levels of carbon-dioxide in oceans affect shelled marine animals. They will carry out a student-developed investigation on how increasing ocean acidification affects these animals.
Objectives
The objective of this lesson is for students to assess how increasing levels of atmospheric CO2 affect marine organisms. In addition, they will devise an experiment to test
Technology geared to the instruction and learning of science concepts, skills, and processes is instrumental to a deeper understanding of science phenomena and content.
Overview
This lesson is intended to introduce students to the concept of scientific exploration and investigation. Students will model the technology used in the Jellyfish in the Bering Sea expedition by using underwater cameras and tow
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 conduct a demonstration that will help them gain a better understanding of the water cycle and runoff in a watershed. They will be able to replicate arctic and non-arctic watersheds by varying the size of the watershed. They will be able to visualize the difference in runoff by creating hydrographs of these different locations.
Students will investigate the breadth and depth of science taking place in the Polar Regions by reading and learning about one PolarTREC expedition and sharing it with the class.
Objectives
* To expose students to the wide variety of science happening in the Polar Regions
* To help students understand the process of science by examining one
