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
By rolling a die, students will simulate a molecule of carbon’s movement with in the carbon cycle. This is a fun, active way to introduce students to the carbon cycle and/or to review the cycle and identify carbon sinks and sources.
Students experience the carbon cycle as CO2 molecules or as stored carbon and travel the path of
Students will explain, both orally and in writing, a diagram used to illustrate a food web.
Objectives
Students will learn how language is used to communicate and is required to impart knowledge and sustain a healthy, traditional community in a modern world.
Students will learn strategies for communicating complex ideas to an audience.
Students discover how different organisms that live in the Arctic depend on each other and what might happen to the food web if one or more organisms disappears from it. Students will build an arctic food web.
Objectives
Students will learn that organisms are part of a global food web and linked to each other and their
As part of a migratory bird study conducted with my bilingual second graders in Washington, DC, the students in my elementary science class spent four weeks getting to know all about birds! We initially focused on birds that migrate from our Mid-Atlantic forests to the tropical forests of Central America (an area where many of them are from)
This lesson came out of a desire to connect the plankton research that I did during the 0902 Healy cruise with my young "researchers" back in Washington, DC. I wanted them to understand that plankton not only feed the Arctic but that much of the world relies on these little critters that come to life for us when we look
This lesson answers the question: How does ice floating on the ocean act as it melts?
Objective
* Students will learn about temperature, salinity and their effect on density.
* Students will learn that ocean currents are caused by differences in densities as a result of temperature and salinity. These differences allow ocean currents to circulate water
