This Week: Here's how it works. I will post a new
Brain Teaser for classes on Sunday evening of each week. These Brain Teasers will be available for the whole
week and are good for extra credit. All you have to do is read the Brain Teaser, fill in the appropriate response
section below, and submit your answer. All submissions go directly to my school e-mail. Be sure to include your name!
(I can't give credit to ghost writers.) If you include an e-mail address, I will respond to your submission. Have fun!
BRAIN TEASER:
Thanksgiving is a favorite holiday for many people! I'm sure you know that this holiday
is a time when we think about those things for which we are thankful. The Pilgrams started celebrating this holiday, according
to the English tradition, as a way to express thanks for a fruitful harvest. But do you know in which year they celebrated
the first American Thanksgiving, how many days they feasted, and with which Indian tribe they celebrated?
Your assignment for this Brain Teaser is to answer those three questions. Submit your
answer by 9:00 pm on
Sunday, November 27 for the extra credit.
HAPPY THANKSGIVING!!!

One metric ton of either feathers or bricks will have an identical mass of 1,000 kilograms (one metric
ton). However, a metric ton of feathers will occupy a volume of almost 400 million cm3 (about the size of four
tractor trailer trucks), while a metric ton of bricks will occupy only one-half million cm3 (about the size of
a large-screen TV). The bricks are denser than the feathers because their mass is packed into a smaller volume. This relationship
between the mass and volume of a substance is what defines the physical property of density:
Density = Mass/Volume
Your assignment for this week's Brain Teaser is to complete the data table to the left.
You may submit your answers the regular way--the submission form--or you can print out
a full-sized version of the table pictured above, fill it in, and turn it in during class. Either way, this Brain Teaser is
good for extra credit!
