Transcript of SCIENCE EXPERIMENT Polishing Pennies!bloximages.chicago2.vip.townnews.com/stlamerican...many jobs...
Background Information: Have you noticed that
pennies quickly lose
their shine? Pennies
are made of copper.
When copper mixes with
oxygen, it creates a
coating called oxide.
Materials Needed: • Lemon juice
• Old, Dull Pennies
• Paper Cups
• Paper Towels
Process:
q Place the penny in a paper cup.
w Cover the penny with lemon juice. Leave the
penny in the juice for 5-10 minutes.
e Wipe the penny with the paper towel.
r Why do you think lemon juice is an
effective cleaner?
Answer: Lemon juice is very acidic.The acid
chemically removes the oxide from the penny. Think of other
ways that lemon juice could be effective.
Learning Standards: I can follow sequential directions
to complete a task. I can make predictions and draw
conclusions.

DID YOU KNOW?
Enjoy these activities
that help you get to
know your St. Louis
American
newspaper.
Activity One —
Diversity in
Science: When you
think of scientists, do
you think of men and women? Do you
picture people of various races? New
technology advances have been made
by a diverse group of people. Use the newspaper
to evaluate how an informative news article is
written. Next, write an article about a scientist
you have studied who has made contributions
with his or her scientific discoveries.
Activity Two — Job Hunt: Use the
classified section to view the job listings. How
many jobs require a high school diploma, an
associate’s degree, a bachelor’s degree, or a
master’s degree? Create a graph to display your
answers. Why are education and job training important?
Learning Standards: I can locate information in
a newspaper. I can write for a specific purpose and
audience. I can display information and draw conclusions.
I can make text to self and text to world connections.
The St. Louis American’s award winning NIE program provides
newspapers and resources to more than 7,000 teachers and
students each week throughout the school year, at no charge.
African -American Chemist and Educator Samuel Massie, Jr.
Samuel Massie was born on July
3, 1919, in Little Rock to parents
Samuel Procter (a minister) and
Earlee Massie (a teacher). Both of
his parents encouraged his love
of education. When he was only
13, he graduated from Dunbar
High School, with the second
highest grades in his class. Massie
then worked at a grocery store
for a year after graduation to
save money for tuition to attend
Dunbar Jr. College. In 1934, he
hoped to transfer to the University of Arkansas, but his
application was rejected because of his race. Instead, he
attended the Arkansas AM&N College and earned a bachelor’s
degree in chemistry with a minor in mathematics. Massie
wanted to study chemistry because he hoped to find a
cure for his father’s asthma. With the help of a scholarship
he earned, Massie was able to afford a master’s degree in
chemistry from Fisk University in Nashville, Tennessee. He
taught there a year before going to Iowa State University to
earn a doctorate degree in organic chemistry.
In 1943, Massie’s father died. When Massie returned to Iowa,
he was assigned to the Manhattan Project, the program that
created the first atomic bomb. Massie and his mentor, Dr.
Gilman, published several research papers in The Journal
of the American Chemical Society. Massie took a teaching
position at Fisk University in Nashville, Tennessee, where
he met his wife. He taught at Langston University, Howard
University, and the National Science Foundation. In 1963,
Massie was named president of the University of North
Carolina Central. He served as the first African-American
professor at the U.S. Naval Academy. While there, he
established the employment opportunity committee and
helped establish a black studies program. He retired in 1993,
and two years later, his portrait was hung in the National
Academy of Sciences Gallery.
In 1994, the U.S. Department of Energy created the Dr.
Samuel P. Massie Chair of Excellence, a $14.7 million grant
to nine historically black colleges and one for Hispanic
students to further environmental research. Massie was
awarded with an NAACP Freedom Fund Award, the White
House Initiative Lifetime Achievement Award, and was
named one of the seventy-five outstanding scientists in
the country by Chemical and Engineering News m agazine.
Massie passed away in 2005.
Learning Standards: I can read a biography about a
person who has made a contribution in the fields
of science, technology, engineering, or math.

What is Chemistry?
There's an atomic bomb museum in New Mexico,
where the first atomic bomb was detonated. The
museum is only open 12 hours per year.
10% of U.S.
electricity is
made from
dismantled
atomic bombs.

Measurements! Scientists often need to use measurements. Answer the
following questions about measurement.
z Put these units in order starting with the
smallest: meter, kilometer, millimeter, and
centimeter. ______
x What are the abbreviations for all metric
distance units in question 1? ______
c How many millimeters are in one centimeter? ______
v How many centimeters in one meter? ______
b How many millimeters in one meter? ______
Learning Standards: I can identify units of
measurement.
What is chemistry? Chemistry is
a branch of science that studies
the properties of matter and how
matter interacts with energy.
Everything you can touch, taste,
or smell is a chemical. Some
popular chemistry topics are
atoms, molecules, and electrons.
If you’ve ever studied water as a liquid, gas, and solid—
you’ve studied chemistry! Did you know when
you cook, a chemical reaction takes place?
When products like medicine, cleaning supplies,
and cosmetics are created, chemistry is used.
Those beautiful fireworks on the 4th of July?
Chemistry was used in their creation. Chemistry
is all around.
Chemists, physicists, biologists, and engineers study
chemistry. Other careers that take chemistry courses
include doctors, nurses, dentists, pharmacists, physical
therapists, science teachers and veterinarians. Fire fighters
study chemistry so that they can learn about the chemical
reactions of products used to fight fires. If you’ve been to
a salon, you’ve seen chemistry in action as the customers
get their hair curled, straightened, and colored. Chemistry
includes math, logic, and critical thinking.

Learning Standards: I can read nonfiction text for
main idea and supporting details.

The first bomb dropped
on Hiroshima was
made from uranium.
The bomb dropped
on Nagasaki
was made from
plutonium,
which was even
more powerful
than uranium.
