How does temperature affect rubber band elasticity?
Procedure Plan – Scientific Method Based Projects
Problem Statement:
How does temperature affect rubber band elasticity?
Hypothesis
If the rubber band is heated then it will stretch more.
Independent Variable: The temperatures.
Dependent Variable: How far the rubber band stretches.
Control variables: Initial rubber band elasticity, wind fluency, time in temperature, how
fast it gets stretched, rubber band type.
Location:
My house.
Materials:
 Rubber bands
 Ruler
 Different temperature areas
 Timer


Safety goggles
Gloves
Safety Precautions:
Safety goggles.
Detailed procedures:
1. I have to stretch the rubber bands (slowly) to make sure they all stretch the same.
2. Then put the rubber bands in the different temperatures and start the timer.
3. When the timer beeps take it out.
4. Then stretch them as slow as you did at the beginning.
5. Record your data.

The rubber bands are combined with acetic and formic acid rubber sheets. The
sheets are then squeezed between rollers to take out the extra water and stretches it 2 or 3
square feet. The rubber is then brought to a rubber factory, where the sheets are cut into
small pieces and mixed in a mixer with other chemicals, sulfur to vulcanize it, pigments
to color it, and other chemicals. After being milled, the heated rubber strips are fed into
an extruding machine that forces the rubber out in long, hollow tubes. After they’re
extruded, the rubber tubes are put over aluminum poles called mandrels. Finally, the
tubes are removed from the mandrels and fed into a cutting machine that slices them into
finished rubber bands.
This article helped me understand that making rubber bands must take a long time
but they’re very useful. It also thought me that rubber bands are not made of silicon. This
article helped me with my project so that when I put them in different temperatures I
know if they would melt or not.

Pik India (June 2, 2009) Rubber band.
http://www.pikindia.com
No matter what type of rubber band, thick or thin, they all should resist
temperature, ultra violate rays, chemicals and oils. Still they have their jobs. Thick
rubber bands are usually used for electrical and, conduction uses. Other are made so they
resist extreme weather and direct sunlight for outdoor uses. Rubber bands are also places
that we might not think they are like shower caps, and goggles.
This article helped me understand that rubber bands are different and are used for
special uses. This article helped me so I would know what type of rubber band I should
use for my project.

Rubber bands are made in a lot of different ways: with silicon, fluorinated
acrylic nitrite, chloroprene, and ethylene propylene diene. Silicon rubber bands are
usually for medical usages like bands for braces. They are resistant to big
temperature change, but they can’t stand steam. Ethylene propylene diene rubber

bands are for chemical usage. They resist chemicals and heat. Fluorinated rubber
bands resist oil, grease and most solvents. Chloroprene rubber bands are different.
They are for outdoor usage, like water proof sealing, machine parts and bridge
bearings.
This article helped me with my project by helping me see which rubber band
would be the best for my science fair project.

Rubber (latex), a type of sap, is found in tropical places like Brazil, Malaysia,
Indonesia, Thailand, China and some parts of India. It originated in Brazil. It is
found in a tree called Hevea Brasiliensis. The Hevea Brasiliensis tree provides
ninety nine percent of the world’s rubber supply. To get the rubber from the tree,
you have to shave a slanted stripe of the bark off the tree about 4 inches deep. Then
the rubber, as a liquid, runs down the cut and at the spout (the end of the cut) then
drains out. To use the same tree, you can do the same thing but on the other side of
the tree. Each draining provides about a teacup of latex.
This will help with my project by telling me if rubber came from a warm or
cold place.

You pour the latex into the tanks and add the same amount of water. They
put the latex and water mixture through sieves to remove dirt, bark, and twigs. Then
formic acids are added to the latex and water mixtures to (coagulate) make it form
solid particles. You then put the crude rubber through rollers to squeeze out the
water and form it into a sheet. Crumb rubber is produced by machines that chop’s or
shred’s the sheets into wet crumbs. The crumb rubber is dried in hot air tunnels and
then compressed into bales for shipment to market.
This article helped me with my project telling me if latex was made in hot or cold
temperatures.

The weather can change a lot within a very short time. Like it may rain for an
hour and then become sunny and clear. Weather includes daily changes in
precipitation, barometric pressure, temperature, and wind conditions in a given
location. Climate describes the total of all weather occurring over a period of years
in a given place. This includes average weather conditions, regular weather
sequences (like winter, spring, summer, and fall), and special weather events (like
tornadoes and floods).
This article helped me by telling me if weather could stay constant.
Hazard chemicals, activities, and devices:
a. Describe risk assessment process and results. The rubber band might pop on
me.
b. Describe safety precautions and procedures to minimize risk. I can wear
goggles to protect my eyes and gloves to protect my hands from the heat or
cold of the rubber band.
