GLUEP BALL EXPERIMENT Darina Vrublevskaya Observations TRIAL ONE TRIAL TWO BALL REST Does not maintain its shape Maintains its shape BALL BOUNCE Does not bounce and sticks onto the desk Does bounce, about 15 cm up THIN STRIP The strip pulls off and falls The strip holds together PULL ENDS SLOWLY Falls apart Gluep stretches far PULL ENDS QUICKLY Falls apart Snaps into two Questions In glue t he tangled molecules make glue thick and viscous rather than thin and runny. When glue is exposed to air, the water evaporates, leaving the tangled polymer molecules. The tangled molecules stick to the surfaces on which they dried, and hold the surfaces together. Borax has ions can form links between the long, thin polymer molecules in the glue which makes Gluep more like a solid than the plain liquid glue. It allows holding its shape for a short time, and as long as it is not strained. When Gluep rests, the flexible network gradually relaxes, and the Gluep flattens. When Gluep is stretched quickly, the links between molecules break, and the Gluep snaps apart into pieces. Gluep contains a lot of water that contributes to the liquid-like properties to Gluep . If the Gluep is left exposed to open air, the water will evaporate, and the Gluep will gradually stiffen. Altering the materials affected the consistency of the Gluep ball because each substance that was added into the mixture had different types of ions which made the texture different, and the Gluep ball act differently too. This is all linked to stoichiometry because it is the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers . In this experiment, we compared substances and have observed different types of reactions to them. Works Cited FLINN Scientific Canada. (2013). Glue Slime.
