PSIP:The New Hampshire and Massachusetts TeamsPresentation slides by Maggie

Before we began our experiments at Tufts University, Po (a graduate student) explained what we were going to do.

From left to right: Mike, Terence, Maggie, Ngawang, Tim, and Ben trying to complete the calculations before conducting the initial experiment. We also worked

with the Massachusetts Team with Sam Kounaves and Dr. Suzanne Young.

We had to the make various molar solutions. Here one of us is using a scale that measures to 10-4 grams.

After the calculations were completed and the solutions were made, the experiments could begin! (left to right:teTerrence, Dr. Young, Ben , Maggie, Ngawang, and Tim)

Po helped to explain the Nernst equation before we left to work it out on our own.

Once the correct amount of salt was added to the flask, “Nano Pure” water was added.

Another part of the experiment was going on at the same time. This is the Antarctica Project which involved crushing up regolith and pouring it into tubes

to be labeled.

This is the finished result.

On our second Tufts visit, we discussed our previous results and then began to make standard molar solutions again and do calibrations test. Each sodium

sensor was calibrated to a particular molar concentration of NaN03.

Testing the electrolytes in a solution.

Scratching the Electrolytes

Dr. Suzanne Young scratched some of the electrodes after the experiment to test the effect that the abrasion would have on the

voltage readings taken in various solutions.

This is the final result.

Patience was a big part of the experiments.
