Which types of mixtures can be separated by filtration?
Students attempt to separate mechanical mixtures, suspensions, and solutions using a variety of filters.
Students have some flexibility as to which mixtures they combine with which filters.
This lab uses Claim/Evidence/Reasoning to make conclusions.

What is the composition of a sand/salt mixture?
In this inquiry, students design a procedure to determine what % sand and % salt are in a mixture of the two.
This lab involves solubility, filtration, experimental design, measurement, and sources of error.
One thing I really like is that students are forced to consider weighing their empty glassware.
(This lab can also be used in the Numbers in Chemistry unit)

What is the melting point of Lauric Acid?
Students are given a clear procedure in this experiment, so that they will collect sufficient and relevant data.
Students work together to determine what their data means, and why the graph is not what they might predict.
