This is the only icebreaker that I use with my high school science students! I've used it for over 5 years and it is always my favorite day of the year. This icebreaker activity allows you to 1) talk science on day one 2) randomly group students for your seating chart 3) spend time getting to know your students and 4) allowing them to get to know you!
So true... it's sad and I've definitely observed it. People aren't aware of their surroundings. People don't chat with fellow travelers in airports or restaurants. Yep it is sad. I have traveled a lot and that was a neat thing to meet folks along the way.
