Astronomical Clocks:
tell the location of celestial bodies and gong once/hr.
There is no 'time' on the dial
& the clock moves using weights.
This clock, mounted in Prague's Old Town square,
has parts dating from 1410AD.

Group #2: What is a derived unit? Provide several examples. Explain how these are different than the fundamental units.
Groups #3-9:

1) determine what your unit can be used to measure
2) what is its symbol
3) how is this unit is defined- might involve a *tiny* bit of history
4) find an everyday thing- how much of this unit?
(for example... a very much not SI, non-metric example... a student at Cleveland is 5.5 feet tall... Do NOT use metric prefixes before your unit... as in the height of Cleveland high school is 10decafeet tall...).
