If you want to, do this experiment again, a different way, using different liquids than you used before. How to test the viscosity of a liquid: 2:36ġ2.The Sci Guys: Science at home-SE2-EPZ: viscosity of liquids 5:54.Seesaw theses pages to your teacher from your Liquids booklet.ġ2.For more experiment variations, w atch these youtubes: Do your experiment, observation, recording & conclusionġ1. Be ready to watch for the order that the liquids finish!ġ0. Pour the same amount of each liquid at the top of the flat cookie sheet, leaving space between, so that the racing lanes are clear or use one cookie sheet for two liquidsĩ. Write the definitions for these vocabulary words in your booklet:Ī) Flow: the action of moving along in a steady streamī) Liquid: substance that takes the shape of a container and has a consistency like water or oilĨ. Answer th ese questions: tell an adult your answersī) Are some liquids faster and some liquids slower?Ĭ) Why do some liquids move faster or slower than others?Ĥ. Each liquid will need its own “racing lane” down the cookie sheet.Ħ. Label your cookie sheet at one end with the 5 liquid names you chose (ok it with your mom!). Get your Exploring Liquids booklet ready, a pencil and these materials: a cookie sheet, masking tape or paper & scotch tape, 5 liquids (some fast flowing & runny, some thick & slow flowing) such as: liquid dish soap, water, cooking oil, bubble bath, paint, toothpaste, honey, syrupĥ. To discuss cases in which the flow is not steady, an equation of motion for fluids is needed. However, the argument has so far been restricted to cases of steady flow. 3.Click on this TAB to see your worksheet from your Science Liquids booklet:Ĥ. fluid mechanics - fluid mechanics - Viscosity: As shown above, a number of phenomena of considerable physical interest can be discussed using little more than the law of conservation of energy, as expressed by Bernoulli’s law.
