Osmosis, Schmosmosis

Little House in the Big Woods 001

Chapter 5

*****

 

I was geared up for a Science experiment to show osmosis.

The word and  definition were vaguely familiar from
my High School Biology class.
I didn’t always pay attention in class, did you?
Good thing my Dad doesn’t read my blog all the time,
because he was my high school Biology teacher.

Remember how I didn’t pay attention to his gold panning lessons?
I must have not been listening too well in Biology, either.

 

We refreshed our minds about osmosis.

That’s alotta’ big words in Dictionary.com’s explanation.

We liked this definition from ASK better.

We cut the potato in half,
sliced off the round ends,
then scooped out the inside.

Good thing I’ve owned a melon baller for about two decades.
It finally earned its keep.

Each potato slice was set in a bowl,
water was added to about 1/2 inch depth,
and the hollows were filled with colored water.

We added 1/2 teaspoon of sugar to one hollow,
and labeled it because I knew I would forget.

Then I labeled the stuff so my family wouldn’t forget.

If you read the corn cob blog,
we have trouble with projects around here.

Since I don’t want to give them impression that things are always perfect around here,
you needed to see the mess that sat here for a few hours.

There ya’ go.

That’s what it looked like the next day.

 

“Trees use a method called osmosis to force water upwards. Osmosis works because there is a difference between the sap, or juice, inside the root and the water in the ground outside. Sap contains large amounts of sugary substances. Ground water contains only tiny amounts of dissolved nutrients.  Sap is more concentrated than ground water.  Osmosis forces water from the soil through minute holes in the root skin to inside the root. p. 37-38 The Prairie Primer

 

 

Here’s another osmosis potato experiment
from someone who probably listened better in Biology class.

 

I was just feeling good that we started and finished a project.
I think some Science stuff musta’ osmosised into our brains,
doncha’ think?
