Make sure to bring proper clothing (Pants, closed shoes, no contacts, etc.)
1 table = 1 (side of) paper!
Part II.

I - Title: Melting Temperature of a Solid

II - Purpose: To observe a change of state while identifying a pure unkownk solid while learning the proper use of:
Bunsen Burner
Ring Stand
Observe a change state, A physical change while carefully making Quantitative and Qualitative observations.
III Procedure:
Significant changes to manual
Come in, obtain a bunsen burner, A ring stand, wire gauze, Test tube containing a solid w/ a thermometer beaker, 2nd Thermometer, and a Flint
Flint is NOT a TOY it is a TOOL

Water Bath
Heat the Bath to 60 - 65 degrees Celsius
