This lesson will provide students with an opportunity to design and carry out an experiment that mimics the conditions causing accelerated ice melt along the face of the Thwaites Glacier off the southwest coast of Antarctica. Created by Sarah Slack during her expedition to Thwaites aboard the icebreaker Nathaniel B. Palmer, this activity aligns with the Science and Engineering
Scientists are studying the effect of climate change on vegetation in the Alaskan tundra. In this activity, students will analyze data collected from control plots and plots with Open Top Chambers (OTC's) over them. An open-top chamber is like a tiny greenhouse that increases the temperature in a vegetation plot an average of 2-3 degrees, simulating the effects of
After spending 5 weeks in the Arctic learning about tundra vegetation and phenology, Alejandra Martinez wanted to have her students observe the growth of plants in their school. In this lesson, students will grow plants in multiple locations and track their growth to compare their phenology.
Objectives
Students will learn what phenology is and make observations about plant growth
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
Article from the Patriot Ledger (Quincy, MA) introducing the Southern Ocean Diatoms PolarTREC expedition. The article focuses on a presentation for North Quincy High School students by Dr. Bethany Jenkins. Jenkins, as well as graduates students from the University of Rhode Island spoke to students about diatoms, life on the R/V Nathaniel B. Palmer and specific tools and techniques related
