at very various time points until the temperature has stabilized (higher
limit). Then place the MudWatt in an ice bath or refrigerator and do the
same thing until the temperature has stabilized again (lower limit).
• Be sure to compare your graphed results to known relationships of
microbial growth vs temperature that can be found on the web (also
copied below). It’s an interesting comparison! Based on your data, can
you determine if your electricity-generating bacteria are psychrophiles
(cold loving), mesophiles (warm loving), or thermophiles (hot loving)?
ExperimentD
Experimental Question: How can multiple MudWatts be congured to
increase the amount of Voltage or Current, or both, in order to power
different things? More broadly, how can the power being generated by the
MudWatts be manipulated to do useful things? (Note: the MudWatt Teacher
Pack is designed to facilitate this exploration)
Independent Variable: The method of connecting multiple MudWatts
together (in series vs parallel)
DependentVariable(s)/Measurables:Voltage, Current, Power
Experiment Notes:
• When hooking up MudWatts in series (i.e. The (+) end of one to the (-)
