In Genetics today, we conducted our Food Lion DNA Extraction Lab. Only one student group brought in a sample for extraction (chicken liver) the rest just relying on me (onions)... lack of intellectual curiosity ... a red flag! The lab is open ended and student driven ... most groups demonstrated some problem-solving promise. We will see as the year goes by ...
Students had to think through how to get to the DNA in the nucleus ... disperse the cell membrane (a lipid problem) by using soap ... then free the DNA from proteins (meat tenderizer) ... pH and cell wall problems ... we will announce the final winner tomorrow.
Selected Topics took their Astronomy test today ... physics continues tomorrow ... Catapult lab on Thursday and Friday.
Introduction to Computer programming finished their array problems today. I did a demonstration on using qBASIC medium resolution graphics and assigned the five problems we will do in the graphics and animation unit. We will check single dimension array programs tomorrow.
Softball conditioning after school ... throwing, frisbee football and some running. We had 20 players attending ... many others are playing volleyball, CC or basketball and will not be available until later.
Stayed afterwards to watch part of the middle school softball game.
Today, was dress like a teacher day leading up to Homecoming. Four chose to dress as the oldest teacher in the building ... though I am still protesting a teacher dress code by wearing khakis and a white shirt nearly every day ... you know how I feel about dress codes ... gosh, Steve Jobs should stop wearing those blue jeans, it is so unprofessional! KP has the lanyards look!
