Time for another Saturday class at CU Boulder taught by the BOLD center engineering women for the Girl Scouts. Today Grace and Hannah did the Home scientist badge while Bethany did the Special agent badge. The CU students have come a long way with the GS program. They used to be disorganized, but now they start on time, have stations that the girls rotate through and in a short time you have done all of the requirements for the badge.
Grace and Hannah were in different groups so I was going back and forth as they went through the stations.
Hannah started with the dancing raisins experiment.
They were investigating the properties of CO2 and density, but really they were watching the raisins go up and down. Grace was making a rocket to study propulsion by alka seltzer.
They went outside to test their rockets and Grace’s shot up a bit, most of the other rockets tipped over, we think the fault was caps that weren’t on tight enough.
There were five stations in all, emulsions, suspensions, static electricity, CO2 and density and propulsion.
Bethany spent her time reading a book while waiting on us. After the girls made it through all five stations it was time to clean up, get the badges and thank our hosts.
Once Bethany’s group got started the girls and I left and went to the Pearl street mall.
It was lightly snowing as we wandered in and out of stores up the street. We went into two bookstores, a toy store, the chocolate factory, art stores and had fun playing on the rocks. What kind of play area do you put on the mall?
Rocks of course, just what every Colorado kids wants to play on. We got back just in time to pick up Bethany. She had been working on: fingerprints, learning about eyewitness testimony, practicing chromatography, learning about body language and writing a scene for a forensic science drama. It sounded like a fun class, but it was for cadets and I’m sure Bethany had fun without her sisters hanging around.
It continued to snow as we drove home, the very tops of the foothills had some snow sticking to them, but everywhere else it just melted. Tomorrow is supposed to be in the 50′s and sunny, quite a change from the last few days, but a hint of Winter was nice to see.
