The Effect of Rubber Band Temperature on The Distance Traveled when Stretched

PROPOSAL
The Effect of Rubber Band Temperature on The Distance Traveled when Stretched

A. Introduction

RAJA SASTRA-In this research, we investigate the influence of temperature on the stretching capabilities of rubber bands and the distance they can travel when stretched. By comparing the distances they can travel when stretched, we aim to provide insights of which temperature of rubber bands can travel farther.

B. Background Data and Information Research

Based on previous research, it can be concluded that observing the effect of rubber band thickness on distance traveled is quite difficult. Some of the results do not support the hypothesis due to the thin and thick rubber band giving the equal result. In this follow up experiment, we are going to focus on another condition that can influence the distance traveled of rubber bands. The conditions that we choose are different temperatures of rubber bands, but with the same thickness and diameter.

Variations in temperature influence how far rubber bands can stretch primarily by affecting the molecular composition of the rubber. At lower temperatures, rubber bands tend to become less flexible and exhibit reduced elasticity because the cold temperature causes the rubber's polymer chains to contract and become more rigid. This restricts the rubber band's ability to stretch and return to its original shape, resulting in a shorter distance traveled when stretched. Conversely, at higher temperatures, rubber bands become more pliable and elastic. The increased heat encourages the polymer chains to loosen and expand, allowing the rubber band to stretch further and recover its original form more readily.

C. Research Question :

1. Is there a significant change in the stretching behavior and distance traveled when rubber bands are exposed to different temperatures?

2. Is there a difference in the distance traveled when rubber bands are stretched at higher temperatures compared to lower temperatures?

3. How do temperature fluctuations affect the stretching behavior and distance traveled by rubber bands, and can these effects be explained through a comprehensive model that considers thermal expansion and material properties?

D. Hypothesis

If the hotter rubber band is stretched, then it will go farther than the colder rubber band stretched at the same amount

E. Protocol

1. Materials and Equipment

Rubber bands

Ruler

Ice Water

Boiling water

Plastic container

2. Procedure

a. Making the different temperatures of rubber bands

● Prepare 5 rubber bands you want to cool. Ensure that the rubber band is at room

temperature or

around room temperature before starting the cooling process.

● Prepare a container large enough to accommodate the rubber band and enough cold

water to fully

submerge it.

● Fill the container with cold water from the tap and add ice cubes to make the water

very cold.

● Fully immerse the rubber band in the cold water.

● Let the rubber band soak in the cold water for 5 minutes.

● Repeat steps a to f but replace the cold water with boiling water

b. Stretching the rubber band

● Hold a ruler on its long edge, with the front end (0.0 mm) flush with the end of the launch surface.

● Place the cold rubber band so that one end of it just catches the end of the ruler.

● Pull the other end of the rubber band back one cm beyond its unstretched length and

hold it down

flat against the ruler with one finger.

● Release the rubber band and measure the distance that the rubber band travels, and

record it.

Measure to the point where the rubber band finally comes to rest, not where it first

touches - the

rubber band may bounce.

● Conduct nine more trials with that same band.

● Calculate the average distance from only five data which has the smallest differences

and record it

on the table.

● Repeat steps a to f but change the amount of stretch to 2 cm, 3 cm, and 4 cm.

● Swap your cold rubber band with the hot rubber band, measure, and record the details

in the table.

Carry out steps a to f with the new band.
