Yesterday, her instructor asked the following question:
"I have in my hand a Douglass Fir tree seed that masses 1 gram [I'm making
this number up, it's not important]. I plant it in my yard, water it
regularly, and wait for 20 years.
At the end of that time, I have a 50 foot tree that masses 1,000 kilograms
[again, I'm making this exact number up, it's not important].
My question is: Where did the 999,999 grams of mass come from?"
I'm going to put the answer out to the group. Where DID the 999,999
grams of mass come from in the tree.
The answer surprises a lot of people. And it brings to question how
much we actually know about science.
I'm going to change my comment moderation policy for this one. I'm NOT
going to approve people whose comments have the right answer, until I post my
follow-up post tomorrow, because once the right answer's been given, it's pretty
clear. But I'll be interested in knowing the percentage of comments that
have the right answer vs. the wrong answer.
