To take this experiment further, you may want to try microwaving the liquid for a short period of time to see if the marble drops through faster when the liquid is warmed. Calculate the average time. Friction between the molecules of a fluid resists fluid change and deformation.

To compare the relative viscosities of liquids, it is easy to use the calculated velocities. You can imagine this with hot glue or melted chocolate.

Warning is hereby given that not all Project Ideas are appropriate for all individuals or in all circumstances. Disclaimer and Safety Precautions Education.

Any other liquid you want to test! Filling the graduated cylinder up with the same amount of liquid each time is not necessarily essential to calculating the velocity properly, but it makes calculations easier if you use the same number for each distance value.

Record the name of the liquid you tested, the original height of the liquid, and how long it took for the marble to fall in seconds. If you want to calculate the actual viscosity of each of the liquids tested, weigh the marble in kilograms. Liquids in which the marble had the slowest velocity had the highest viscosity.

Related learning resources Science Project Face Recognition and Race This project explores if people more easily distinguish between faces of people of their own race or ethnicity compared to those of other races or ethnicities. Why is this important? Repeat the experiment 2 more times for each liquid so there is enough data to take an average.

Viscosity of liquids is often very temperature sensitive, with most liquids and gases becoming less viscous thinner as they heat up.

The distance is the height of the liquid, and the time will be the average time calculated in Step 6.

Procedure Fill the graduated cylinder with one of the sample liquids. High viscosity fluids like honey and glue resist the changes caused by these forces the best.

Reading and following the safety precautions of all materials used in a project is the sole responsibility of each individual. Some brands or types may be more or less viscous than others.

You can then calculate the viscosity by using the equation below: In addition, your access to Education. Implementation of any Science Project Idea should be undertaken only in appropriate settings and with appropriate parental or other supervision. How can you tell which liquids are thicker and which are thinner using the velocity?

Simultaneously drop the marble and start the stopwatch. Be sure to fill each the cylinder up to the same height each time.

Leave a couple of centimeters at the top so it does not overflow. Hold the marble at the opening of the graduated cylinder in one hand and the stop watch in the other hand. Liquid glue, honey, hand sanitizer, glycerin, syrup, cooking oil, water.

Use the web to find out! Stop the timer when the marble touches the bottom of the cylinder. Results Viscosity from greatest to least: The weight of the marble, which is the gravitational force, also causes stress on the liquid.Wet PVT Lab PETE Lab # 6 Determination of Viscosity for oil samples Learning Objectives Gain a basic knowledge of the techniques used to measure viscosity.

Viscosity Measurement Objectives for the student: is important to know the viscosity and how it varies with temperature in the design of lubrication systems, fluid transport, etc.
