Week 2 (9-26-16) The Triangle Test

All right. Not gonna hide it.  Awesome day.

We started with the question, “How do we observe science?” Which is really like asking, “how do we observe anything?”

And when we figured out it was with our senses, hands shot up all over the place.

We look; we hear, we touch, we smell and we taste.

Then it was all about explaining the Triangle Test, which focuses on how keen our sense of smell is at discerning similar scents.

How the Triangle Test works is this: Our blindfolded friends (which is eventually everyone) get to smell two similar scents. For our first round here, the peel of a lemon and the peel of a lime were rubbed on separate coffee filters.

Clean, people. It smelled clean in here.

For ten minutes.

Then each blindfolded person was told which scent was being held below his nose.

20160926_084739

So whether it was lemon or lime Wyatt smelled first, doesn’t matter.

20160926_085109

But let’s say the first scent was lemon. The next coffee filter put below Wyatt’s nose is lime. And it’s not a secret.  I say, “Wyatt this is lime you’re smelling.”

20160926_084802

Then for Cody, like for Wyatt, we choose a mystery filter–either lemon or lime to wave under his nose.

20160926_084808

But we don’t tell Silas or Cody or Wyatt or anyone blindfolded what we’re holding under their nose on this third filter.

20160926_085224

Because it’s here on this third coffee filter that Benjamin has to decide correctly if he smells lemon or if he smells lime.  He was told on the first one, “this is lemon,” and on the second, “this is lime,” but on the third (which will be either lemon or lime), ain’t nobody sayin’ a thing.

20160926_085242

Here’s how we keep track. If the third-filter guess is correct, we’ve passed the Triangle test. First round, anyway.

Riley takes a big whiff.

20160926_085504

And Miss Lisa does.

20160926_085516

And Miss Mandy.

20160926_085635

And that closes up Round ONE.

Round TWO. Can we smell the difference between basil and oregano?

Here’s a sniff of oregano.

20160926_085855

Or maybe it’s basil.

20160926_085859

Definitely oregano.

20160926_085928

Wait. Basil.

20160926_090025

Well now. Trending is the blindfold look.

20160926_090334

And it catches on quickly.

20160926_090427

Very quickly.

20160926_090437

And like that, it’s Round THREE.

Wow. We’ve got a heckuva blindfold happening here.

20160926_090714

All right. This one was hard.

Two similar scents of cheap cologne (Tone and Sport). Sprayed heavily on coffee filters in the parking lot rather than condemning the classroom to a junior high locker room.

20160926_090905_001

Is it Tone?

20160926_091013

Or is it Sport?

20160926_091023

“Sport,” says Lisa. “Definitely Sport.”

20160926_091139

And the answer is…oh my…Tone!

20160926_091204

Today’s sniffers and Triangle Test peeps.

20160926_091348

The people who had the most fun. And their photobomb clientele.

20160926_091647

So then. What do you do with the extra lemons and limes?

Why see how fast you can strip the enamel off your teeth.

20160926_091922

And…you’d think it was a race.

20160926_092001

A little color coordinating going on.

20160926_092007

A little twinkle behind those eyes.

20160926_092015

And pain.

Definitely pain.

20160926_092025

Alrighty.

Here’s a final look at the board.

20160926_092058

Fun stuff.

See you all in a week!
