One activity was injecting DNA- dyed pink- into little divots of a tray. This tray is then placed in water with an electromagnetic(?) pulse for some 30 minutes, which will move the DNA samples at different intervals to see dominant and recessive alleles. You can see this more clearly under a florescent light.
My favorite activity was slicing mouse brains. I wrote about this a few weeks ago. (See that post HERE). It was fun to finally be able to do this in person. To do this, the machine must be at -13 degrees celsius so the brain is firm enough to cut, but not frozen. Then you crank a wheel and it cuts a piece off. To collect this sample, you take a slide and slightly tap it on the slice to pick it up. The brain will melt onto the slide because the room temperature is higher than -13 degrees celsius. You can even see some of the structures by holding up the slide to the light.
Another activity was viewing brain cells under microscopes to see the Kisspeptin that was being released. The room we viewed these cells in had boxes and boxes of slides- each box containing 100 slides. I also learned that each slide has 4 slices of brain, and a mouse’s can use up to 25 slides.
I loved this trip because it was very hands on, and not every high school student can say they visited a research lab for a field trip.
