Electrofishing

 On the last week of school, Teresa Conrad brought her EskDale physics class to Great Basin National Park. They looked at differences in water quality and streamflow between a spring and a stream. Then the real fun began: electrofishing. First Mark and Jon got out the multimeter to explain how the electrofisher worked.

 Then it was time for the students to get in the stream and take their turn capturing fish that were stunned by the electrical shock.

They learned about proper net placement.

 They caught quite a few fish!

I don't think any of them guessed there were that many fish in a 50 m stretch of stream.

It was a perfect activity for the end of the school year, with great weather.
