What middle school students doesn't like talking about emitting odors? :) The boys thought this video was 'cool' and girls thought it was 'gross', but they all remembered about pheromones the next day!
This documentary on the weird underground mating habits of the leopard slug is narrated by David Attenborough and sponsored by MMD (www.moneymakerdiscussion.com/forum/regi­ster.php?referrerid=80778), who made such profound and groundbreaking scientific research possible in the first place.

 
When my class was studying conditioning I used this video. We first talked about what pigeon's behaviors are when raised in the wild. We had a class discussion about pigeons and boxes. Do pigeons instinctively know what a 'box' could do for them? We watched the video a few times and then talked about what conditioning really means.
Real laboratory footage showing a pigeon solving Wolfgang Kohler's famous box-and-banana problem, which he studied with chimpanzees in the early 1900s. Dr. Robert Epstein and his colleagues used operant conditioning techniques to get pigeons to solve this problem "spontaneously" in the 1980s. A report of their research was published in the prestigious British journal Nature in 1984 ("Insight" in the pigeon, Nature, 1984, v. 308, pp. 61-62). Depending on their previous experience, pigeons could solve this problem in a human-like fashion in as little as a minute. This pigeon has learned to push boxes and to climb, and it has been rewarded with grain for pecking at a small toy banana. In this situation, the banana is out of reach and the box is not beneath it. At first the pigeon looks confused, then it begins pushing the box - sighting the toy banana as it pushes - and then stops pushing when the box is beneath the banana, then climbs and pecks. This and related studies were summarized in Dr. Epstein's 1996 book, Cognition, Creativity, & Behavior.

Students love to watch animals interacting with their environment! This is a great video with narration to explain why and how octopus have camouflage.
