I like to show this 2:35 minute film found on the internet during my lessons on Characteristics of Living Things. On the short worksheet students are asked to check off which characteristics of life they observe. The creator of the Beach walkers is highly entertaining himself.
After the video I ask students to support a claim about whether or not the Beach walkers are living using evidence collected from the video itself.
In December of 2014 these creations were on display in Miami. I've added the 2:54 video link produced by the New York Times as an extension opportunity.
