Although the precise definition is some. Therefore, we’ve shown that corn syrup and honey have a higher viscosity (or are more viscous) than water and cooking oil. 14 ChemMatters, DECEMBER 2004 Non-Newtonian fluids and viscosity. In our experiment, the marbles took longer to sink when dropped into the jars filled with corn syrup and honey than they did when dropped into the jars filled with water and cooking oil. The more viscous (or thick) a liquid is, the longer it will take for an object to move through the liquid.
Viscosity can also be thought of as a measure of how “thick” a liquid is. Liquids that have a HIGH viscosity flow slowly (ie. water, rubbing alcohol, and vegetable oil). Liquids that have a LOW viscosity flow quickly (ie. Viscosity depends on the size and shape of the particles that make the liquid, as well as the attraction between the particles. Viscosity is a liquid’s resistance to flowing. The question answered in this experiment is: how does the consistency of a liquid impact how long it will take for a marble to sink in a jar of that liquid? A unique property of liquids is something called viscosity. Watch the Viscosity of Liquids Science Experiment Step by Step Instructions How Does the Science Experiment Work? Define viscosity as a liquids resistance. Lesson Objectives SWBAT (Students Will Be Able To): 3rd-8th. Viscosity of Liquids Science Experiment Video tutorial variables that might affect their viscosity. It also contains ideas on how you can expand on the experiment. This structure, depending on the thickness of the. The more viscous (or thick) a liquid is, the. Some bacterial cells release a viscous substance that accumulates around the cell and coats the cell wall. Was your hypothesis correct? Do you know why some marbles sink to the bottom of the jar quickly and some marbles sink to the bottle of the jar slowly?įind out the answer in the how does this experiment work section below. Viscosity can also be thought of as a measure of how thick a liquid is. You’ll notice right away that the marble behaves differently in each jar. Drop one marble at a time and observe what happens to the marble when it enters the liquid. Step 2 – Carefully drop one marble into each jar.
