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

AM Quincy television interview with Quincy Access Television broadcast anchor Joe Catalano. This interview is a follow-up to the August 8th interview on the Currently in Quincy program. PolarTREC teacher Cara Pekarcik discusses her upcoming expedition and plans for community outreach.
In this lesson students research scientific field expeditions and learn what it is like working in the field. Students are able to ask questions of the research team as part of their project. Students then share what they have learned with their classmates.
Objective
1. Students understand what really goes on in the field during a scientific study.
2
An important science skill that needs to be developed is asking significant questions that advance knowledge. This activity helps students to understand the difference between significant and trivial questions.
Objective
Students should be able to distinguish between significant questions that advance knowledge and trivial questions.
Procedure
1. Have the students define significant question and trivial questions in a
In this activity, students diagram the hydrologic cycle. Most of the concepts will already be familiar to middle and high school students, but this activity is a good way to prepare for making the far more challenging carbon cycle and energy NON-cycle diagrams.
Objective
* Students understand that the total amount of water on Earth is constant
In this activity, students diagram the flow of energy through the Earth's ecosystems. A lot of the concepts presented here are necessary in order to fully understand the greenhouse effect and global warming. This lesson is presented as an activity to do before embarking on a study of the greenhouse effect and global warming. Unlike water or carbon
In this activity, students diagram the carbon cycle. A lot of the concepts presented here are necessary in order to fully understand the greenhouse effect and global warming. This lesson is presented as an activity to do before embarking on a study of the greenhouse effect and global warming.
