Therefore, we’ve shown that corn syrup and honey have a higher viscosity (or are more viscous) than water and cooking oil. 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. Adjust, as necessary, the temperature of the. water, rubbing alcohol, and vegetable oil). Select the viscosity cup which is sized appropriately for the liquid to be tested. 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? Viscosity of Liquids Science Experiment Video tutorial It also contains ideas on how you can expand on the experiment. 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. 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.
