Dancing David said:It does not take an advanced degree.
It takes methods and protocol, which is what you mainly discussed.
That is the beauty of the scientific method, it is available to all,
ANYONE should be able to conduct the test , it does not require any advanced knowledge, just appropriate procedure.
On the general experts are only needed if the precision one wants is very high or if the subject of the study itself is not measurable by simple devices anybody can use.
The desired precision in this case depends upon JREF and Dalton. Dalton claimed that when ice without rock is melted, the remaining block has more than 80% of former mass. As JREF certainly would be satisfied with 60% as well and assuming an intial weight of the cube of 100 g, the precision should be +-20 g with a result of 80g+.
This precision is reachable by anybody with a freezer, a hammer, 10 thin glasses and a standard electrical kitchen balance, as these devices have a precision of +-5g or better.
Procedure:
Fill each glass with 100 g of water and let it freeze.
After freezing brake glass away with hammer(ice is far more stable than thin glass).
Use 6 glasses for training, so that no ice is broken away, use balance to check for.
Take a room without windows, choose two spots for the devices, which are identical except for exact position(e.g. on same table) and measure temperature at both spots, which should not differ.
Prepare device with rock and test device, which is identical, except for rock and put them there.
Out of the 4 remaining ice cubes take the 2 which differ least in mass and choose one randomly for the device with rock.
Wait till you cannot see any ice in the test device, then weigh the ice from the rock device.
If more than 65 g test made, between 55-65g redo test with higher precision(maybe an "expert" is needed), beneath 55 g, bad luck for Dalton.
This is a scientific test, though it has a lousy precision, none higher is needed, as the difference between 80 g of ice and 0 g of ice is fairly big or as someone put it, either it does melt or it does not.
And as we can see anybody could perform it, if he had Daltons device, even Dalton could and should do so.
Now do not complain that this precision is inadequate for something that might be so important, let me tell you something:
In real science it is not unusual that, that first measurements in a new field are succesful, if the difference between theory and experiment is less than a factor of 10.
Then of course work begins and precision has to get better, but a rough measurement at first to test something is very scientific, as it saves a lot of work.
And nobody would keep Dalton from getting real scientists after he passed JREF challenge.
