biology Design an experiment

Design an experiment.
Don’t focus on the technical aspects of how to measure something. For example, say you are
interested in seeing how a molecule affects the brain, with the hypothesis that the molecule reduces
some activity in a region of the brain. In your experiment, you can simply say you introduce a 1x
amount of the molecule, a 2x amount, a 3x or 4x amount, etc…. and you then measure activity in
the brain using imaging equipment. You can also say your molecule has a tracer (like an isotope, e.g.)
so you can follow where it accumulates. Notice you do not have to specify the molecule, the tracer,
or the way you are measuring the effect. You can then give the results (e.g. there was no change in
the region of the brain, but the molecule also failed to accumulate in that region, so it was either not
transported or was metabolized/degraded).
Model systems are a good way to do research. Examples include using cells where you might follow
a response cells have to a new medication. Or using other organisms and non-human animals – for
example, genetic studies often use everything from bacteria and yeast, to worms, fish, mice, etc…
Because this is a thought experiment, and because ethics is less a consideration, these are options to
think about but aren’t things you need to include.
