It's not exactly molecuar- or microbiology but in my daughters'
school I had good success with a simple gel-filtration.
Syringe column, Sephadex G-25, mix of hemoglobin (lyzed blood)
and cupper sulfate or tincture of iodine and chlorophyll
(spinach extract). Colors get mixed and then separated again
in front of kids' eyes.
Same thing goes for agarose electrophoresis. I ran
Promega's 6X loading dye (3 colors moving) plus (over)loaded DNA
ladder was stained with Crystal violet.
As others suggested purifying DNA from onions, maybe you'll have
time cutting with huge excess of EcoRI/BamHI. Cut vs non-cut on
a gel will be very visual.
