This Bitter Be Good

Another great SciGirls meeting in the books!


This week, the girls tested the glucosinolate levels in various veggies (orange pepper, carrot, broccoli, and cauliflower), by using PTC (phenylthiocarbamide) paper, a blindfold, and a taste test.  The girls had very interesting results!

The challenge:  Determine whether tasting the bitter compound PTC influences which vegetables a person likes.  They brainstormed ideas, did their taste tests, and documented their results on a chart.









After the SciGirls challenge, they had lunch, and got to enjoy a brief "recess" outside.  We're finally getting some warm weather!  It's hard to stay cooped up inside.

For the second half of the day, we had a special guest from Mad Science MN!  She led the girls in a few cool chemistry experiments.  They had an explosive good time!

Next week the girls will tamper with robotics by building a robot arm that can actually lift things!  They'll finish up with a field trip to the Apple Store for a cool workshop.  We can't wait!
