Warm up 04-07-14 • Question: Name some topics for tomorrow’s test • Answer: • forces, gravity, friction, net force, newton’s laws, momentum • Goal: I will review for the test.
Element of the day • 87 – Francium – Fr • Francium is the least-stable naturally occurring element with a half-life of 22 minutes, and was the last element discovered in nature (in 1939 in…FRANCE!) • Francium should be the most reactive of the alkali metals, but it is so radioactive, that we’ve never put together a lump of it big enough to test.
Warm up • Soda bottle reminder • Review Lab 6C • Lab • Tonight’s HW • 2 liter bottle (THURSDAY!) • Ch 6 packet 1-43 • Test TOMORROW! Agenda / HW
