Ferromagnetism can be used to separate iron, cobalt, and nickel from a mixture. Eddie/Foucault currents can be used to attract non-ferromagnetic metals.
Density Separation

In this video, you will see 3 separation techniques that separate heterogeneous mixtures based on differences in density. In decanting- the liquid supernatant is poured leaving the denser solid behind. You can also use a pipet to suck off the top layer. If you are dealing heterogeneous mixture of liquids, you can use a separatory funnel to drain the denser liquid.

This video explores 4 polarity lab stations that demonstrate the relative strength of the three main intermolecular forces (dispersion forces, dipole-dipole forces, and hydrogen bonds). This video goes along with this lab packet: docs.google.com/document/d/1GMf_dNN96cqsxJ8IZFhe2OgMCwacz0ad59eykx3D1YY/copy

This video shows how a Vernier SpectroVis works on the inside.
Interesting. A very good demonstration.
nice, thx for the upload! Could i use a similar process to separate sand from the flecks of metal in it (out of the local creek?)
