Alex's Science Project - Experiment II



Song:  Rolling in the Deep

Rendition:  The Piano Guys




Alex's second experiment dealt with the strength
 of the total Adhesive Molecular Attraction of differing materials...to that of water.
I taught him that it depends on the configuration of the material...which in this case...
the results are produced through capillarization.

I had also taught him that it was a product of Adsorption rather than Absorption.


Alex tried different materials singly...
in differing configurations...


and in various combinations.



His objectives for this experiment were to grade individual materials
as to their ability to attract water...and the ease at which they released it...
to list each with the pros and cons...
to try to combine various materials to get the most strengths from each...
and to properly configure them...as well as shape them, to achieve the desired effect.

Alex tested the ability of the material to attract water by observing the rate 
at which water was extracted from a capillary.

Alex then tested the materials for its saturation point...
and the rate of clearance through the release of the water...
as again tested through water extraction from a capillary.

His experiment proved to be a success.

We were able to determine the best combination of materials...
and the best configuration to allow constant extraction...
only because of the materials used, and the configuration of the final product...
allowed constant drainage of the extraction point, which kept it below its saturation point.

I told Alex that in order to engineer this product...
the point was to get the materials with the highest total adhesive molecular attraction...
and the most surface area...and to decrease the total adhesive molecular attraction...
 and the surface area, in succession...
and to take out surface tension from the equation by not allowing the water
to gather into a drop...which could greatly slow...or even stop, the process.

Again, although, both, the concept, and the final product, are very simple...
I cannot show it as of yet.

Alex will be entering a competition with it.


The third experiment will prove to be the most daunting.

The forces we will be dealing with are so small...
and the engineering of the apparatus needing to be so finely tuned...
that it will prove to be a lengthly process.

We are only using the most basic of materials to build it.

Even should Alex not be able to construct it...
he can show how the concept is theoretically sound...
and how it could be constructed using different materials
(carbon fibers and magnetic levitation).

Neither Alex, nor I, have very good fine motor control...
nor have we a lot of patience...
and this next phase shall demand a lot of both.




Fall is still affecting the neighborhood trees.

It is so nice this time of year.









Alex enjoys just walking through the neighborhood.

The air is a very nice temperature...
although today was a little warm for me (75 degrees).
However, the nights dip into the 30s...so it is nice.

Next week, we shall have highs in the 50s and lows in the 20s.

That is more like it  :)
