How+Does+Temperature+Affect+The+Ability+Of+Silly+Putty+To+Stretch

Sarah G  Cary Academy  ** ABSTRACT ** The purpose of this experiment was to find out if the temperature of the Silly Putty affects the Silly Putty’s stretch ability. The method for this experiment was put the yellow, pink, or glow in the dark Silly Putty in the microwave, refrigerator, or freezer for 20, 25, or 30 seconds. The Silly Putty was stretched and the pull was estimated on the spring scale force. The hypothesis for this experiment was that when the Silly Putty was put into the freezer it would be harder to stretch, and when the Silly Putty was put into the microwave it would be easier to stretch. The results of this experiment was that when the Silly Putty became looser and easier to stretch than its normal state. When Silly Putty was put into the freezer the Silly Putty became stiffer and harder to stretch. An example was, when the glow in the dark Silly Putty was put into the microwave for 20 seconds, the spring scale force was 10 Newtons. When the glow in the dark Silly Putty was put into the microwave for 25 seconds, the spring scale force was 8 Newtons. The spring scale force decreases when the Silly Putty was put into the microwave for a longer amount of time.
