Greetings from a PIE Scientist
Have you or your
students ever found
yourselves asking
questions about the
seasons. Why do we
experience different
seasons? What causes
the weather to change
so drastically
throughout the year?
Does everyone around
the world experience
the same type of
seasons at the same
time?

find some answers to
these questions. They
participated in the
P.I.E Seasons activity,
which gives students
the opportunity to
discover the reason for
seasonal change.

Science Puzzle
Q: What is the difference between mass and weight?
A: Mass is an accounting of all the atoms in an object and how large
they are and is measured in grams. Weight is how much gravitation
force is exerted between two objects (the earth and your body) and is
measured in pounds of force. A person who is more massive, will
weigh more then a smaller person on the same scale. But when they
travel into outer space, the gravitational pull between the person and
the earth is less, so they will weigh less then they originally did.
However, they will still have the same body mass.

Literature
Literature is another tool for science instruction. Using exciting or
interesting science literature can entice also challenged readers.
Here are some recommended books that address 6 th grade
indicators.
Nibbling on Einstein's Brain by Diane Swanson. There is a lot of
faulty science research. It's difficult for the public to discern what
science is good and what is misleading. This book takes a fun and
informative look at the scientific facts that constantly bombard us.
The Road to There: Mapmakers and Their Stories by Val Ross.
Ross presents a look at several mapmakers and the way that their
work reflected not only physical boundaries, but also important
aspects of their lives and the times in which they lived.
Looking For Life in the Universe: The Search for Extraterrestrial
Intelligence by Ellen B. Jackson. Jackson describes how scientists
use 21st century technology to investigate whether life exists on
other planets.
The New Way Things Work by David Macaulay. Grouping
machines together by the principles that govern their actions rather
than by their uses, Macaulay helps us understand in a heavily visual
way what gadgets such as a toilet, a carburetor, and a fire
extinguisher have in common.
