Straw Rockets
Science Standards: The way to change how something is moving is by
giving it a push or a pull. The size of the change is related to the strength,
or amount of force, of the push or pull.
To make your own straw rocket at home:
You will need:
• Drinking straw
• Pencil
• Scissors
• Tape
• Templates A and B on this page
Enjoy solving
this frog maze by
drawing a line
from the frog to
the flies it would
like to eat!
Template A (rocket body)
Do this:
1. Cut out Template A (rocket body), wrap it lengthwise
around a pencil and tape it so that it forms a tube.
2. While still on the pencil, create a nosecone by twisting and
then taping one end of the paper tube.
3. Cut out Template B (fins) and tape them to the lower part
of your rocket.
4. Next, carefully slide the rocket off of the pencil and onto a
straw.
5. Before you launch your rocket, make sure that no one is in
the pathway of your rocket.
6. Now blow through the straw to launch your rocket by using
a pushing force!

Great White Shark Migration: Scientists
tracked the movement of 30 Great White
sharks and noticed that most of these sharks
stayed near the coast of South Africa, but one
shark traveled almost 7,000 miles in 99 days!
Where did this shark travel to?
Tracking Turtles: Scientists were able to
track the movement of one hundred
Loggerhead Sea Turtles across the Pacific
Ocean. Did scientists find that they liked
to travel in warmer or colder waters over
time?
Ice and Snow: The amount of ice and
snow on Earth changes throughout a
year. Notice that the North Pole of the
Earth is mostly water and the South Pole
of the Earth is land. Which month have
scientists discovered has the most
amount of snow and ice in the Northern
Hemisphere?
When it is winter in the Northern Hemisphere, which season is it in the
Southern Hemisphere?
Making Ice Rinks: Touch the ice. Water freezes
at 32 degrees F. At which temperature do hockey
players like their ice to be?
Is that colder or warmer than the temperature at
which ice freezes?
You Be the Shooter: Notice when you use the
hockey stick that you are applying a pushing
force with the stick. The energy from your body
is given to the stick. Notice that the energy
from the stick is given to the puck which makes
the puck move. How many pucks were you able
to shoot?
Did you score a goal?
Sounds of the Game: Sit in the Sounds of
the Game exhibit to learn about the science
of sound. Sound travels in waves. Listen to
Ryan Getzlaf’s voice change when Wooly
Argyle, our sock puppet, plays a trick on
him. Did the pitch of Getzlaf’s voice change
higher or lower?
