The "Magic" String
Hoover, Todd F.
Science and Children, v48 n2 p32-35 Oct 2010
The "Magic" String is a discrepant event that includes a canister with what appears to be the end of two strings protruding from opposite sides of it. Due to the way the strings are attached inside the canister, it appears as if the strings can magically switch the way they are connected. When one string end is pulled, the observer's expectation is challenged when an opposite end they do not expect is the one that moves. This article describes how the author uses the "Magic" String to teach students about differentiating the science process skills of observing and making inferences. (Contains 5 figures.)
