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
When radioactive elements decay they emit high-speed particles. These can be detected by use of a cloud chamber. The cloud chamber was invented by Charles Thomson Rees Wilson in 1911. The chamber works by saturating the air inside with alcohol vapor. Cooling the chamber with dry ice supersaturates the air. The energetic particles produced by the radioactive decay ionize
This is a suite of labs created by Michigan State University and the Joint Institute for Nuclear Astrophysics (JINA). It provides a number of lessons and activities in nuclear physics. It can be used to demonstrate the types of reactions typical in cosmic ray interactions and the interactions that the CosRay neutron monitors depend on.
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
The Energetic Ray Global Observatory (ERGO) is a program that will provide students and teachers with a small detector that is capable of detecting the cosmic rays in a manner very similar to CosRAY and IceCube. The unit is small and will allow data to be exported automatically to Google Maps.
Plans for the Berkeley National Laboratory cosmic ray detector. This detector can be built by high school teachers and can be used to study cosmic rays in a method similar to the antarctic particle studies (CosRAY and IceCube).
Kevin Tavares and his fourth graders at Old Hammondtown School in Massachusetts built a website to share what they were learning with the rest of the world. Mr. Tavares installed a location tracking device on the page that assigns a red dot to the country of each visitor. The students wanted to get website hits from all seven continents so
Lake El'gygytgyn (67.5º N, 172º E) is one of the best preserved large asteroid impact craters on earth. In the winter of 2009, I joined an international science team and traveled to the frozen arctic lake to drill and extract lake sediments to study climate change as well as sample the rocks that were changed when the crater
The sediment in Lake El'gygytgyn, (pronounced EL-ge-GIT-gin) located in NE Siberia, holds one of the longest records of climate change anywhere in the continental Arctic. How does sediment (clay and mud) tell us something about past climate? Proxy data! By studying the microfossils of diatoms and pollen in the sediment, we can re-construct the lake environment millions of
