Section 1,

UCSC genome browser.
Problem: Some students changed the setting of the display control and was confused by the display.

Section 2,

Go through many questions.

Problem in math percentage calculation. 500ml 0.5%, how much do we need? I wrote on the board
500x0.5% = 2.5 which confused many students. They think I skipped some steps.  Another student
explained it as  0.5% = 0.5mL / 100mL = x / 500mL, and find out x. This made the students said that now they got it.
