Basic Idea:

• Calculate the pressure some depth below the water surface.
  
• Use Archimedes' principle to calculate buoyant force.

	Short metal rod (40 cm long)	1	non-Majors storeroom, shelf A3
New Stuff:
	Small plastic container	2	non-Majors storeroom, shelf HH3
	Plastic jars, large and small diameter	1 each	non-Majors storeroom, shelf HH2
	Vernier calipers	1	non-Majors storeroom, shelf BB3
	Aluminum block with string	1	non-Majors storeroom, shelf HH3
	Force gauge	1	non-Majors storeroom, shelf F2
	Pendulum clamp	1	non-Majors storeroom, shelf C3
	Roll of masking tape	1	In the lab
Place the following items on the sink (shared):
	100 ml beaker	2 or 3	non-Majors storeroom, shelf HH3
	Sand	Two small plastic containers	non-Majors storeroom, shelf HH3
	Cardboard box lid (from paper box)	1	non-Majors storeroom, shelf HH3
	Electronic Balance	1 or 2	Jeff will get this
The following items are for the pre-lab demo:
	Small plastic container	1	non-Majors storeroom, shelf HH3
	Aluminum block with string	1	non-Majors storeroom, shelf HH3
	Large force gauge	1	Lecture-demo room (Jeff will get this)

Notes:

• Lab Setup (photo details):
  • Hang force gauge from outermost connector on pendulum clamp
  • Place containers with sand and 100 ml beakers on the sink. Put sand containers into cardboard box lid to minimize spills
