Penny Spin
OUTCOME: Students are introduced to inertia while spinning a penny in a balloon.
STATE SCIENCE STANDARDS5.2P.1 Describe how friction, gravity, and magnetic forces affect objects on or near Earth.5.3S.1 Based on observations and science principles, identify questions that can be tested, design an
experiment or investigation, and identify appropriate tools. Collect and record multiple observations while conducting investigations or experiments to test a scientific question or hypothesis.
5.3S.2 Identify patterns in data that support a reasonable explanation for the results of an investigation or experiment and communicate findings using graphs, charts, maps, models, and oral and written reports.
5.3S.3 Explain the reasons why similar investigations may have different results.
POTENTIAL STUDENT PRECONCEPTIONS: An object keeps moving because something keeps pushing on the object. Centrifugal force is an outward-seeking force that we feel when we are in a car that turns quickly or a carnival ride that moves in circles.
SUPPLIES IN THE KIT: gem-tone balloonsSUPPLIES TO FIND: pennies
PROCEDURE OVERVIEW1. Demonstrate inertia and friction with a penny and a balloon.2. Read about motion.3. Challenge students to repeat the experiment with one change.
In this lesson, students learn that an object that is moving will keep moving unless it is forced to change speed or direction. The balloon exerts a centripetal force on the penny.
Friction between the penny, the balloon and the air in the balloon causes the penny to slow and stop moving.
This activity might be used to practice parts or all of the inquiry process.

TEACHER BACKGROUND
Inertia is a property of matter that causes an object to resist any change in direction or
speed. An object at rest remains at rest unless a force causes it to move. An object that is
moving keeps moving unless forced to change speed or direction.
A penny that is moving continues to move in a straight line unless acted upon by an
outside force. The balloon in this activity forces the penny to move in a circular path.
The balloon exerts a centripetal force on the penny. This term comes from the Latin
centripetus, which means "center seeking". Centripetal force causes an object to move in a
circular path.
There is a force described as "centrifugal" that in reality does not exist. If a person is
driving a car and suddenly turns right, he or she will feel thrown into the driver's side door
of the car. Actually, the driver's body has a tendency to move forward in a straight line and
the car prevents this from happening. The car exerts a centripetal force on the driver.
A family takes a ride at a carnival on the Ferris wheel. The Ferris wheel causes the members
of the family to move in a circular path. The
ride exerts a centripetal force on the family.
After the balloon in the experiment stops
being shaken, the penny will stop moving.
Friction between the balloon and the penny
and the energy needed to compress the air
in front of the penny as it moves causes the
penny to slow down and stop moving.

PROCEDURE IN DETAIL
1. Place a penny inside a balloon. Inflate the balloon and
twist the mouth to keep the air in the balloon. Show
students the penny and balloon set-up.
Hold the balloon and brainstorm why the penny doesn't
move. Explain to students that an object at rest stays
at rest unless forced to move. That's inertia. The penny
has not been forced to move. There's friction between
the penny and the balloon. Friction between the penny
and the balloon hinders the motion of the penny.
Option: On a lined sheet of paper have students record
their ideas for why the penny does not move. Have
them share with close-by peers and then the class.
Continue to use the paper to take notes and record
information about the activity.
Give each student a balloon and penny. Ask them to
insert the penny into the balloon, inflate it, twist the
neck, and shake the balloon.
A few students will find that the penny starts to spin
in the balloon. This encourages other students to shake
their balloon so that their penny starts to spin.
Ask students to stop shaking their balloons and hold
them still. They'll see that the penny continues to move
in the balloon.

INAsk students to explain why the penny continues to move.
(The penny has forward motion, and there is minimal friction
between the penny and the balloon, so little energy is needed
to compress air in front of the penny as it moves.)
Ask students to deflate their balloons and set them aside.
Explain to students that there is a second part to inertia.
An object that is moving continues to move unless acted on by a force. Friction eventually
causes the penny to slow and stop.
2. Read about motion (SEd 3)
or ( SEs 03).
Option: Listen to the text
( AU 03).
Option: Students answer short essay questions on their own paper or
a student worksheet ( SW 03/101).
3. Challenge students to change the experiment to see if it makes a difference in how long
the penny spins.
Does the penny spin longer if the
balloon is shaken or rotated to get
the penny started? What if the
balloon is inflated with different
amounts of air? What if it is held
on the sides or held by the top and
bottom of the balloon?

Time how long a penny spins using the classroom clock or a stopwatch. Change how much air is in the balloon, how it is shaken, or how long it is shaken, and see if the penny spins for more or less time.
Two videos of the activity have been saved to the teacher disk, the activity ( VI 03/101) and the activity close-up ( VI 03/102).
Option: Use this activity to practice writing up the Form part of an inquiry work sample. Students write what they know about inquiry, what they want to know, and what they expect to happen. Inquiry worksheets (CC INQUIRY 1-6) and a projection master (CC INQUIRY 7-8) guide students as they record the activity. These resources are used repeatedly throughout the program. Assess student work using inquiry scoring guides.
BE SAFE: Excuse any students from the activity if they have a latex allergy. Avoid this
activity if the allergy is acute and will put the student at risk.
BE SAFE: Caution students that the balloon may pop. If a balloon pops, the student must
bring you all the pieces and retrieve the penny to receive a new balloon.

Center of Gravity
OUTCOME: Students learn about center of gravity while balancing their bodies, their pencils, and cards with paper clips.
STATE SCIENCE STANDARD5.2P.1 Describe how friction, gravity, and magnetic forces affect objects on or near Earth.
POTENTIAL STUDENT PRECONCEPTION: It's possible to balance an egg on its end only on the equinox.
SUPPLIES TO FIND: For each student–index card with paperclipsPREPARE: Attach paperclips to a card for each student. Locate and prepare the image tiles according to directions included in the materials kit.
PROCEDURE OVERVIEW1. Show images of balanced objects. Brainstorm what the images have in common and what conditions result in a balanced object. Students try to balance on one foot and then try to touch the floor. 2. Explain center of gravity. Students balance a pencil and an index card.3. Students balance a card on a pencil using paperclips. 4. Read about center of gravity.
Gravity is a force that pulls objects together. An object has point at which all mass is evenly distributed and it is balanced.
If an object is centered over this point, it is stable. If an object is not centered over the balance point, it is not stable.

TEACHER BACKGROUND
Gravity is a force that pulls things together. We notice the Earth's gravity because the Earth
is so massive. If the material in an egg is balanced over a point, the center of gravity, the egg
will balance on end, no matter what day of the year. It's easier to balance the egg if the end has
bumps like the ones shown in the center image and enlarged 30x in the image at right.
Inertia is a property of matter that causes it to resist any change in motion in either
direction or speed. An object in motion continues to move or an object at rest remains at
rest unless forced to change speed or direction. An object's inertia is determined by its mass,
the amount of material in the object. The more mass an object has, the more inertia it has. An
object at rest with very little mass, like a ping pong ball, is easy to move. An object at rest with
more mass, like a bowling ball, requires more force to move.
LIFT YOUR FOOT
In this activity, you must move into the wall to balance
on the left foot. The wall prevents you from moving, and
so you cannot lift your foot for more than a second or
two before putting it back on the floor. Gravity pulls
you toward the floor. If the material in your body is not
balanced over your feet, you will fall.

ON
4CENTER OF GRAVITY
TOUCH THE FLOOR
In this activity, you will find that you cannot touch the
floor easily. You must move back into the wall to stay
balanced over your feet. When the wall prevents this
motion, you move past your balance point. If you move
too far, you will fall to the floor.
BALANCE A CARD
In this activity, you will see that the card balances on
a pencil if there is the same amount of material in each
direction from the balance point over the pencil. If the card
tips, that's the side that's has more mass than the other
side. Slide the card so that the side that's tipping off the
pencil is moved toward the pencil.
BALANCE THE CARD WITH PAPER CLIPS
When you balance a card, you will see that the card balances if
the mass of the card is centered over the balance point. In this
example, the balance point is the centered over the eraser.
BALANCE A HAMMER
A capable student will find that the head of a hammer
has a great deal of mass. To balance the hammer, the
student's fingertip must be next to the head of the
hammer to balance the head with the small amount of
mass in the handle.

conditions required for an object to be balanced.
Challenge students to balance against
a wall. Take students into a hallway with
space on the wall for each student. Tell
them: Turn and place your left ankle
against the wall. Place your left hip
against the wall. Place your left shoulder
against the wall while you tuck your left
hand behind your body.
After students have done this, suggest they lift the right foot off the floor for a few
seconds. Remind them it is important to be safe. Falling to the floor is not an option.
Ask students why it isn't possible to lift the right foot. Explain that to lift the right foot, a
person's center of gravity must shift over the left foot, and the person's body would have to
move into the wall. Since the wall is solid, this is impossible.

safely for several seconds. Suggestions might
include: move the left foot out slightly from the
wall; hold onto something like a door knob or
molding on the wall to help support the body;
have a second person hold the person in place.
Challenge students to lean forward and
touch the floor. Tell them: "Stand with your
back to the wall. The backs of both feet
should touch the wall. Bend over carefully
from the waist and touch the floor."
Some students may slide down vertically,
bending their knees to touch the floor by
their feet. Ask the class to touch the floor
while keeping their legs straight.
Ask students how the experiment could
be changed so that it is possible to touch
the floor. If a person holds onto a doorknob,
it's possible to bend over far without falling.
However, it's usually not possible to go all the
way down to the floor this way.

2. Explain that objects have a balance point. It can be called the
center of gravity or center of mass. This is the point in the object
where all mass, or material, in the object is evenly distributed around
the point. Gravity pulls the object toward the Earth. If all the mass is
evenly distributed around the point, the object balances.
Revisit the images ( PM 04/101-103 or PR 04/101). Have students identify the center
of gravity (center of mass) on the objects (child, top, rock) shown in the images.
Ask a student to balance a pencil horizontally on the end of an index finger. Students will
see that the balance point is not in the middle of
the pencil. The balance point shifts slightly toward
the eraser because of the extra mass in the metal
ferrule and eraser.
Option: Balance other readily available objects, including an eraser, ruler, crayons, etc.
Show students how to balance a card on the eraser of a
pencil. Place a card on the eraser end of a pencil so that
there's an equal amount of card on all sides of the balance
point in the center of the pencil.
Explain to students that the card has a balance point like their bodies. If there is the same
amount of material on all sides of the balance point, the card will balance on the pencil.

TEACHER BACKGROUND
Inertia is taken from Latin and means "lazy". If an object is at rest, it will stay at rest. If an
object is moving, it will continue to move. Only if a force acts upon an object will it change its
speed or its direction.
In this experiment, gravity pulls the penny toward the Earth as the loop pushes up on the
penny. Unless a force is applied, the penny will stay at rest.
If you push the loop from the
outside edge, you compress the
loop and this pushes the penny
into the air.
The loop resists movement (has
inertia), so it changes shape
before it moves off the jar.
If you catch the loop on the inside edge,
you pull the loop out from between the
penny and the jar, and the penny falls
straight down. The loop moves out of
the way of the penny.
The penny’s inertia causes it to resist
movement. Gravity pulls it down. With
nothing between it and the jar, the
penny falls into the jar!

PROCEDURE IN DETAIL
PREPARE: Cut a file folder into strips that are 1" x 11". Bring the ends together and tape
them to create a loop for each team. Make a few extra loops in case one is damaged.
1. Set up the activity. Ask each student to fold a sheet of lined paper in
half vertically once and horizontally to form four rectangles. Explain that
they will be attempting an activity, and each variation they attempt will
be described with words or drawings in a rectangle. After the attempt,
they are to write a sentence explaining the results of the attempt.
Demonstrate how to set up the activity:
Place a loop on the mouth of a jar.
Place a penny on the loop directly above the mouth of the jar.
Challenge teams of students to get the penny into the jar. They cannot touch the penny.
Many will ask for clarification. Explain that the rules are simple: get the penny in the jar and
do not touch the penny.
Caution children about flying
pennies. Remind them to keep their
focus on the experiment.
Hand out a loop, a penny, and a jar
