Lat night during my Science Methods (teaching) class, we were evaluating the lesson plans each of us were developing. One of the students is doing his on weights and measuremnts and stuff like that. he had expressed the desire to transfer to the students the importance of accurate measurements to include the conversions feom English to metric.
Naturally, the first thing that pops into my mind was the probe sent to Mars that was lost because different people working on the probe used different measurement systems, or something like that. Both he and the teacher thought that would be a great example, but none of us could remember the exact details nor even the name of the probe. I've tried to look fo it, but searching under "Mars + probe" is not narrowing it down enough.
Can anyone help me out here? Thanks!
