Today's lab was about studying the process of active transport, and how it actually works across the skin, in frogs.

I have had a really hard time getting this lab up and running here, in part due to instrumentation issues, in part due to unknown tissue physiology factors. For the very first time, this year, it actually worked. There were a couple troubleshooting moments, but it was such a RELIEF to have it work this time around, so that I could focus on ensuring that my students were actually learning and thinking about how active transport works across membranes, rather than just having them all slumping over in defeat and frustrated because they're just number-crunching some mysterious numbers that some other person collected once upon a time. Yes, they still had to do some number-crunching, but for them it's so much more powerful when it's THEIR numbers that they observed and collected themselves.

I was even able to get a short video recording of the setup in action:


There were even a couple of moments of, "Why did this happen after we carried out this manipulation?" where I was able to get them to look back over the provided information and put the puzzle pieces together.

What a relief.

Now I really need to get up and go home for the night.
