Lesson Description
• Balloon Races
• Newtons First Law
• Newtons Third Law

5
Newtons First Law
• An object at rest will stay at ______
• An object in motion will stay in _______
• UNLESS a force acts upon that object
• Ex. Your sister will continue to sit on the sofa
unless you kick her. Then, she will get up and
beat the snot out of you.

6
Newtons Third Law
• Forces always act in equal and opposite _____.
• In pairs, come up with an example of this and be
ready to share it with the class.

7
Objectives
• The students will be able to
• Identify the conditions under which an object
will obey Newtons First Law.
• Describe forces as they apply to Newtons Third
Law.

8
JOBS
• Materials Person
• Recorder
• Timer
• Spokes Person

9
Materials Person
• Get the materials
• Put the materials away when done
• Help keep your area clean

10
Recorder
• Complete hand outs with data
• Use legible handwriting
• At the end, write data on board

11
Timer
• Tell your group when you press start
• Press stop when other group members say so
• Be accurate, two digits after the decimal point

12
Spokes Person
• Come to an agreement with your group before
speaking
• Speak clear and loud enough to be heard
• When speaking, respect others

13
Materials
• 3 balloons of different sizes and shapes
• 3 drinking straws
• String
• Tape
• Markers
• Stop Watch
• Calculator
• Meter Stick
• One Balloon Race Sheet per person in group

14
Step One
• Run a string across the classroom to make a race
track. Tape one end of the string securely to a
wall. Leave the other end loose.

15
Step Two
• Thread the string through one straw. Tape the
straw length wise to the middle of the zigzag
balloon with the open end pointing towards the
loose end of the string.

16
Step Three
• Blow up the balloon. Hold it closed.

17
Step Four
starting point for your races. This should be
directly above the nose of your balloon.

18
Step Five
• Have one person tightly hold the string level
horizontally. As the timer says GO and starts
the stopwatch, the person holding the balloon
closed lets go.

19
Step Six
• Stop the stopwatch when the balloon stops moving.
Record time to the nearest 100th of a second (two
places after the decimal point) in the
appropriate data table.

20
Step Seven
point for this run. This should be directly above
the nose of your balloon. Measure the distance
the balloon traveled in centimeters. Record the
measurement to the appropriate data table.

21
Step Eight
• Repeat steps 3 through 7 two more times with the
same balloon.

22
Step Nine
• Repeat steps 2 through 8 with the straight
balloon.

23
Step Ten
• Repeat steps 2 through 8 with the oval balloon
EXCEPT blow up balloon prior to taping it to the
straw.

24
Step Eleven
• Calculate the average speed for each trial and
then the overall average speed for each of the
three balloon racers.

25
Data Analysis
• Send the Recorder up to the white board to record
your groups data into the correct location.

26
Closure
• As a group, discuss the following questions and
have the Spokes Person ready to share your
• What aspects of these balloons made them travel
far and fast?
• How does the Balloon Race Experiment relate to
Newtons First and Third Law?

27
Objectives
• The students will be able to
• Identify the conditions under which an object
will obey Newtons First Law.
• Describe forces as they apply to Newtons Third
Law.
