Nature + Numbers = 1
Fascinating Book
It would be easy to see Lifetime: the amazing numbers in animals lives by Lola M. Schafer as another science/nature/animal
book.
But it’s even better to
think of it as a science/math book that uses facts about particular
characteristics (behaviours or features) of animals and how many times
something will occur for that animal within an average lifespan.
Here are a few of my favourites:
*Mountain caribou will grow a
new set of antlers 10 times over the course of its life.
*A male seahorse will be
responsible for producing 1,000 baby seahorses over its lifetime.
*And, over the lifetime of a
giant swallowtail butterfly, it will sip the nectar of about 900 flowers.
Each animal is featured on a
2-page spread that also shows the 10 sets of antlers, 1,000 baby seahorses and
900 flowers. (I didn't count these last
ones and I'm OK with trusting the illustrator on these points.)
The mathematical aspect of
the book is marked in a few ways. The
book starts with the number one. “In one
lifetime this spider will spin 1 papery egg sac.” It moves onto the 10 sets of antlers grown by
caribou. Next, we learn that alpacas
grow 10 different fleeces over their lifetimes.
And, on it goes with each animal featured with a progressively larger
number of occurrences, characteristics or behaviours over its lifetime.
Background information about
each animal and the basic equation the author used to work out her statistics
is provided here. This is where I
learned that mountain caribou travel as far south as Washington,
Idaho and Montana
from British Columbia, Canada. I did not know that, and thought they stuck
to northern latitudes. Also, on average,
a caribou lives 8 to 12 years and is 2 years old when it grows its first set of
antlers. Thus, 12 years for lifespan – 2
years for maturity = 10 years for antler production. 10 years for antler shedding x 1 set per year
= 10 sets altogether.
The statistics for the
seahorse are more involved but tell you that over the average lifespan of a
seahorse in the wild, 1 ½ years, they birth a lot of babies every few months to
average the 1,000 baby seahorses mentioned above.
The author includes an easy
to understand explanation of what an average is and how she came up with her
numbers for each animal.
The author’s fascination
with numbers is apparent and applying them to the lives of the animals she
wanted to learn more about is explained well. She takes us through the thrill
of discovering that an American lobster will sheds its exoskeleton on average
80 times with most of this shedding occurring in the first year of its life. She presents a couple of ‘word problems’ for
kids to work through themselves to figure out how many times an armadillo will
roll into a ball and how many scorplings will a Florida bark scorpion produce over
their lifespan.
A terrific book with lots of
interesting facts gathered and presented in a cross-disciplinary way that will
work in elementary classrooms.
