For this activity, the students are going to draw on their own knowledge and experience with weather to predict the current temperatures around the world and then compare their predictions with real-time weather data from selected locations around the world. The students will then be provided with several factors that affect both daily changes in temperature and climatological temperature
This is a radio interview with WESA (Pittsburgh Public Radio) on "The Confluence" with PolarTREC teacher Mike Penn and Kevin Gavin. Penn's interview starts at approximately 18:05.
In this 20 minute podcast interview, PolarTREC teacher Mike Penn sits down with Brian Crawford and discusses his upcoming trip to Antarctica. This interview took place on 9/23/18.
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
Podcast of the live TV interview with QATV journalist Joe Catalano. This interview is a follow-up to a previous discussion about the PolarTREC expedition.
Through activities, video observation, experimentation and the construction of a Remotely Operated Vehicle (ROV) students will learn about the chemical and physical properties of sea ice.
Objectives
Students will be able to answer main questions of where sea ice is, how it is formed, why the ice is important, how it is classified by indigenous people and scientists, how
Nature creates its own density column in marine systems, which is extremely important for the triggering of the spring bloom of phytoplankton. Phytoplankton are an important food source for all organisms- from microscopic zooplankton to large marine mammals such as walrus and whales. The different salinities (and therefore, different densities) of water help to stabilize the water column (by limiting
Students are asked to predict what will happen to styrofoam objects lowered down to the bottom of the Bering Sea. Students make the appropriate calculations related to the actual experiment which took place on Maggie Prevenas' PolarTREC expedition.
Objective
Students will make hypotheses and calculations regarding deep sea experiments that took place in the Bering Sea on
Students will sort organisms found in the Bering Sea into food chains and gain an awareness of the flow of energy and nutrients in the Bering Sea Ecosystem.
Objective
Students learn about the different organisms that live in Alaskan waters by playing the Fabulous Food Chain Game. In playing the game, they become aware of the flow of energy
