Rico Period 3 ES 9th Graders

This video clip depicts a student group who had stated a very nice claim and had provided evidence and reasoning.  Their Floating Bubble experiment involved comparing bubbles over dry ice to bubbles over regular ice.  The main student in the clip, "Andrew," leads the group, but then leads them off into the wrong reasoning! 
Teacher Claim:  Students can be misled by a student they perceive as "smart."
Evidence:  At the beginning of the clip, "Tara" (off-camera) says, "Anyway... what are we writing?...so the bubbles are not (inaudible-"hovering?") on regular ice because the dry ice is giving off a certain gas...?"   "Andrew" responds:  "It's cold...cold air is heavier than regular air...so when bubbles are like that (gestures into the tank)..."  "Tara" then responds, "Okay, shush...you like to say too much words."  "Kurt" then asks (almost inaudibly), about what to write for reasoning, and seems to be questioning the reasoning.  "Andrew" again mentions coldness as the reason for the bubbles floating.  This is despite their results, that indicated that regular ice would not float bubbles! 
Reasoning:  "Andrew" is a clearly intelligent natural leader who took over the leadership role quickly in this group despite there being two other intellectually strong students.  "Tara" puts forth the idea that the floating of the bubbles has to do with a gas being given off, but gives in quickly to "Andrew," as does "Kurt."  What their papers say (the Claim/Evidence/Reasoning worksheet) will be discussed in my second entry.
