| This lab was adapted from an experiment developed by Peter Amati, a teacher who participated in the Teachers Experiencing Antarctica and the Arctic Program. You can check out his activity and many others at http://tea.rice.edu/tea_classroom materials.html | |
 |
 Students collected ice samples from three basic depths; the top, middle and bottom layers of the sea ice. |
 |
 |
| As part of their sea ice studies, the science classes prepare artificial ice cores to compare with real sea ice. Here, Dylon and Jesse take an 8 foot piece of pvc pipe out of the doubled insulated tube. The insulation was used to slow down the process of freezing so that the the core simulates the process of salt being precipitated out as the water freezes. | |
 |
 |
| Students removed the ice core using a broom handle on the opposite end. They cut the samples off in one foot lengths for future testing. | |
 Vernier computer software was used to determine salinity levels of sea water and sea ice. |
 Jesse and Thomas prepare 1: 4 dilutions of the salt water to use with the conductivity probe. |
 Rachel uses an old the old fashion titration method for determining salinity. |
 Mr. Irelan checks the results from the conductivity meter. |
 Katie uses an old the old fashion titration method for determining salinity. |
 Taylor and Shane prepare 1: 4 dilutions of the salt water to use with the conductivity probe. |
| Two systems of measurement were used to determine the salinity of the salt water collected at different depths (10, 20, 30, and 40 feet), the different sections of actual sea ice (top, middle, and bottom, using an ice auger), and of our artificial ice cores. Students used standard titration tests and a Vernier Conductivity probe and computer software. | |
