We are 7th and 8th graders from the ESL Science class at Lincoln
Middle School in Passaic, New Jersey.
The purpose of our project was to find
the boiling point of water. At the beginning of the project, we formulated the
hypothesis "Many variables could have an effect on the boiling point of water,
these are room temperature, volume of water and elevation".
After we conducted the experiment, analyzed the data and graphed the results
from different schools around the world, we discovered that elevation was the
factor that have the most effect on the boiling point of water. Although we
found some inconsistencies when we were graghing the data, the trend of the
graph showed that the higher the elevation, the lower the boiling point of
water.
We had a lot of fun working on this project and we want to thank all the
participants in this project.

Final Report from Bethel Middle School 3rd Hour Class -
Shawnee, Oklahoma, USA
We asume the water is at room temperature. As heat is
added the water molecules will move faster as evidence from the process of water
bubbles. Water molecules will continue to move faster as the heat increases over
time this can be seen from the increase of water bubbles. According to the
thermometer the temperature is increasing and it will continue to increase
untill it reaches the boiling point of 100 degrees celcius. When it has reached
the boiling point the temperature will level out and the increasing temperature
will be used to turn the liquid into gas. It will reach the boiling point in
five to ten minutes.
No, our hypothesis was not completely correct. We predicted that the boiling
point would be 100 degrees celcius and our boiling point ended up being 95.875
degrees celcius. We also predicted the boiling point would be reached within 5
to 10 minutes but it took much longer. It ended up taking about 30 minutes. We
used 250 millilitters of water. We used hot plates to heat the water. If we did
the expirament again we would get new equipment. Our hot plates were old and
didn't heat very fast. Also, our thermometer was about 4 degrees off.We don't
feel that the room tempeture, which was 16.66666667 degrees celcius, changed the
boiling point only the time.
That is the final report from the Bethel Middle School
7th grade 3rd hour
Science class.
Final Report from Bethel Middle School 5th Hour Class-
Shawnee, Oklahoma, USA
Our hypothesis was that the boiling point would be
100 degrees. We assumed as heat is added water molecules will move faster as
evidence from the process of water bubbles. The water molecules will continue to
move faster as heat increases over time this can be seen from the increase of
water bubbles. We used 250 mL of water in a 4 degrees celsius off thermometer.
We also used a hot plate. Most of the recorded boiling points were between 90
degrees and 100 degrees. Most of the elevations were between 0 and 600 above sea
level.Our class did not prove our hypothesis. We found out that the average
boiling point was 95 degrees. One of the reasons our average boiling point was
below 100 degrees is because our elevation is below 100.
Final Report from Champaign Central High School -
Champaign, Illinois, USA
While doing our boiling point project for the GEMS
club, we found that Charles' and Boyle's Laws still hold true in these hectic
times. We hypothesized that elevation (231 m in our case) would be the greatest
factor in determining the boiling point of distilled water. Volume plays a role
in the time it takes for water to boil. Temperature is closely related to the
time it takes to reach boiling point.
When we looked at the project's data, we found that some points were no where
near the line of best fit. These were probably caused by undistilled water or
chemicals left in the beakers.
Group Data:
The strongest relationship existed between elevation and
boiling temperature, as shown by the high correlation coefficient. The
temperature of the water and the volume of the water used were not closely
related to the boiling temperature of the water (low correlation coefficients).
Final Report from Miami Springs Middle School -
Miami, Florida, USA
We did this project two times. The second time we did
this project we decided to do it with three types of water,
distilled,
spring, and tap, this is the one we wanted to post. Unfortunutely, we
did'nt get our data in on time. However we have decided to post part of our data
here so you can see it.With the first type of water, spring we got an average
boiling point of 87 degrees celsius of 4 different readings. Our second type of
water was tap, and we got a average boiling point of 92 degrees celsius of
another 4 readings. Finally our last type of water was distilled water, of 4
readings we got an average boiling point of 96 degrees celsius. In total we got
an
average of 91 degrees celsius. In conclusion we found out that diffrent
types of water will have diffrent boiling points.
Final Report from Hartland Middle School - Hartland,
Michigan, USA
Our class participated in the International Boiling Point
Project to find out if water boils at different temperatures and what would
cause the temperature to be different. Our science book tolds us that water
boils at 100 degrees Celsius. After completing the project and looking at the
data some schools got water to boil at different temperatures. Through analysis
of all the data it was concluded tha elevation had the greatest effect on the
temperature at which water boils. The reason why there were variations in the
data might have been from errors in the procedures followed by the students.
Maybe students didn't use distilled water, or they didn't calibrate their
thermometers before the investigation started. This project was fun and we
learned a lot about science investigation. We enjoyed discovering what factor
has the greatest effect on the temperature at which water boils, and we would
love to participate in another fun collaborative project in the future.
Final Report from E.G. Hewitt School - Ringwood, New
Jersey, USA
We learned many things doing this experiment. Our original
hypothesis was that elevation would affect boiling point. We thought water(H2O)
would take longer to boil in the mountains. We learned that water boils at a
lower temperature (91C) in the mountains and a higher temperature (100C) at sea
level.
We graphed Boiling Point vs. Elevation. It was "awesome" to see the graph.
"Sometimes you have to make a diagonal line in your mind when looking at the
graph." When we looked at the graph we "saw the connection in my mind". We were
surprised to see so many experiments were done at low elevations.
There were many different temperatures recorded at the same elevation. We
were wondering if this was due to different kinds of water, chemical
contamination, or, maybe the thermometers were not calibrated correctly. We were
excited to be sharing this experiment with students all over the world. Thanks
to everyone who joined us on this adventure.

Final Report from Hart High School - Hart, Texas,
USA
We had fun with this project! Interpreting the graphical data was not as
easy as some of us thought it would be. Our latitude and longitude
investigations were interesting. We would like to thank you for allowing us to
participate. Our determined controlling factor for the boiling point of water
turned out to be pressure; hence, elevation. If we could do this again, we would
use different heating devices and other materials. Some of us feel that these
things might have some influence on the boiling point.
