Alright, looking at this passage down here about alzheimer's, let's go ahead and go down through the list and talk about how it relates to each part of the scientific method.
00:15
The observation here in this example is that the drug that was originally created to treat diabetes actually has a positive effect, i'm just going to say, positive effect on the central nervous system activities, even though it was not really effective against diabetes.
00:40
But that is the observation being made here.
00:43
The question, let's look at next, the question at hand is, could this drug be used to treat dementia? and if so, how is it going to affect the central nervous system? how does it affect the central nervous system? now looking at the hypothesis, the hypothesis is going to be something along the lines of this drug can be used to treat dementia, and it does this by blocking glutamate receptors, and this is to prevent overactivation, which in turn may prevent neurotoxicity within the central nervous system, ultimately reducing cell degeneration and death.
02:25
That's going to be the hypothesis here.
02:28
I left out a few of those words, let me just read that one more time.
02:31
The drug can be used to treat dementia by blocking glutamate receptors to prevent overactivation, which in turn may prevent neurotoxicity in the central nervous system, ultimately reducing cell degeneration and death.
02:44
That's going to be the hypothesis here.
02:47
Alright, next, the prediction.
02:54
So based on this hypothesis, a prediction could be if the drug is administered to individuals with dementia, it's given to people with dementia, it will slow down or improve their cognitive decline compared to a control group receiving a placebo...
