Soap Bubbles and Qualative Observations ( Bonus: Inferences!)

Dear Kalpita,

You may remember how I was wondering about soap bubbles. Of course I was so wrapped up in hydrophylic and hydrophobic soap molecules/atoms/whatever , that I completely overlooked the obvious answer. Air gets trapped underwater. Air is lighter than water so the air bubble rises and gathers soap. The soap helps it stabilize and not pop the moment it comes out of the water. It breaks the waters surface and we have a bubble of air with a skin of water and soap.

Fun Fact: If you want to put anything in a bubble it must be wet.

I feel so idiotic now. Oh well. It is 11::32 and my mind is refreshed. I shall have to do a post about the difference between atoms and molecules. I KNOW the difference but not really.  My new lesson is in observations.

Everyone knows what an observation is. But there are two types of observations, or so i am informed. They are:

Quantitative: These are observations using charts, numbers and/or graphs
Example: A tree is 15 foot tall
The average amount of water drops that fit on a penny is 16

Qualitative: This is an observation using one or more of the 5 senses.
Example:  The leaves on a tree are turning brown
A fruit is turning rotten

If you want to go into some details to help you remember which is which, remember this
Quantitative is another form of the word Quantity which is an amount
Qualitative is another form of Quality  which means: a property or attribute

Since you can not study an observation without having an inference be just around the corner, I shall talk about inferences and get it over with.


Inferences- The process of drawing a conclusion, using logic and statistics.

So I shall make some inferences on the following subjects

1. 3/4 of the leaves on a tree are dry, brown and shriveled. 
My Inference: I infer that 3/4 of the tree is in a heavily shaded area. perhaps another tree is blocking out all possible sunlight on that side of the tree. This might explain the leaves being brown and shriveled. Another factor is,obviously, rain. The sentence says that the leaves are dry so the other tree probably blocks out a lot of the tree's valuable water sources. Or perhaps it is just a drought but this would not fully explain why only 3/4 of the tree's leaves are dead.

2. A cat played with a mouse for 15 minutes but didn't eat it.
My inference:  The cat is probably a housecat, otherwise it would take any meal it saw. The cat is probably well-fed anyway and was practicing hunting. or perhaps it was just bored and wanted to play. After the cat had batted the mouse around for 15 minutes the mouse was probably in pretty bad condition, making it look much less appealing to eat.
