Information regarding our schedule:
There is NO class next Friday, October 22nd; it is a holiday at TPU. The next scheduled class is on TUESDAY, October 26th （金曜日の授業）. HOWEVER, I must teach at Toyama Tandai on that day. So, our 3rd class will be face-to-face on October 29th. There will be a make-up class at the end of the semester. There is no problem about this.
Session 1: Look at the picture on p. 109. You can watch the video here:
The part where she licks the frog from about 2:20, so I suggest you watch from the beginning until this point. After this, most of the video is about insects. How does she test whether the frog has toxins? She says one word; what is it?
