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
There is a plausible explanation for how carbon dioxide molecules could interact with water molecules thereby forming a solution where the carbon dioxide is the solute and water is the solvent (as it usually is). The weak inter-molecular attractive forces rely on the polarity of the water molecule and the high density of electrons at either end of the
When a bottle or can of carbonated beverage is opened the carbon dioxide is allowed gas to come out of solution. This is because there is a pressure differential between the carbon dioxide in the liquid and carbon dioxide in the air. The pressure in the liquid is higher than the pressure in the air so the carbon dioxide moves
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
I spent a month on a boat in the Arctic as part of the 28 member Science Team that lived and worked alongside the 53 member Crew of the Canadian Coast Guard Ship Louis S. St. Laurent, a 392 foot icebreaker out of St. John's, Newfoundland
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
