The Pouring Test – When you are finished dropping the marbles into the jars, try pouring the liquids one at a time into another jar.Tip: Timing the marble, works best when using liquids that have a high viscosity (ie. How long will it take? Expand on the experiment, by estimating how long it will take for the marble to sink to the bottom of the jar? Then set a timer and find out how close your estimate was.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. 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? 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. What do you notice as you pour the water into the glass? What about the corn syrup, the cooking oil and the honey? Did you notice anything different?ĭo you think the liquid will impact what happens when a marble is placed into each jar? What do you think will happen? Write down your hypothesis (prediction) and then continue the experiment to test it out and to find out if you were correct. Step 1 – Gather four clear glass jars and fill one with water, one with corn syrup, one with cooking oil (we used vegetable oil, but any cooking oil will work) and one with honey.Īs you are pouring the liquids, take a moment to make observations. Viscosity of Liquids Science Experiment Instructions Cooking Oil (enough to fill one jar) We used Vegetable Oil, but any Cooking Oil will work.4 clear glass jars of the same size (we used pint-sized mason jars).JUMP TO SECTION: Instructions | Video Tutorial | How it Works Supplies Needed We’ll help define viscosity in our easy to understand explanation of how it works below, but the goal of this experiment is to help kids ‘see’ viscosity in action.Ĭollect your materials, print out our detailed instructions, and watch our demonstration video to explore how the consistency of a liquid impacts objects. Viscosity? If you’ve never heard this word before you might think it’s a new brand of kitchen cleaner! But of course, if it’s not a kitchen cleaner, what in the world is it?
