Intro/Hypothesis
Intro I did my project on bridge building to see
what two different types of bridges would hold
the most weight. Hypothesis My hypothesis is I
think the k style bridge will hold the most. I
came to this conclusion because I think the k
style bridge looks stronger. When I firs started
this project I just hoped I would get it done.
The summary of my project is I built to different
types of bridges and tested them to see witch one
would hold the most weight

Materials
The materials you will need for this project
is. 1. Wood Glue 2. Small weights 3. Popsicle
sticks That should be it.
5
Step by Step Procedure
1. Build the two different bridges of your
choice. 2. Put them across to tables and add
weight. 3. Record your data.

EXPERIMENT
I did my project 2 different types of bridges to
see witch type could hold the most weight. To do
this project you will need Popsicle sticks,
glue, and small weights. The two bridges I did
was a k style bridge and a v style bridge.
The first thing I did was built the two bridges.
The k style bridge was the first bridge I
tested. I put the bridge between two tables and
then I started adding weight. At about 5 1/2
pound it it started to break the center, but it
held out to 6 pounds tell the glue gave out and
it fell to the floor. Next was the v style
bridge I put it across the same 2 tables as the
other bridge. Then I started piling on the
weight. Once the weight got to 5 pounds I thought
it was going to break but it held out to 6 pounds
passing the k style bridge. And was the
toughest bridge of the day. This was a pretty fun
project and I would suggest it to other people
who like building things.

Background Info
People have been building bridges for thousands
of years. So the could get from one end to the
other. Back in the olden days the mainly made
bridges out of wood because stone was to
expensive. But in the early 1900s they started
building more stone bridges because they were
more reliable and they looked better then wooden
bridges.

Discussion Data Analysis
The v style bridge was better because it held
more weight based on my information.

Conclusion
After I did this experiment I found out that I
was wrong the v style bridge held more.

Acknowledgments
I would like to thank any one who helped me build
my bridges. And any one who helped me with the
writing and power point.

Most my information I got from what I already new
but the other stuff that I didnt know I got of
the internet.
