Viscosity Race: Liquid Flow Experiment

This document provides the procedure and questions for an experiment to determine the viscosity of different liquids. Students will time how long it takes for water, cooking oil, syrup, and honey to travel down an inclined plane. They will then analyze the results to identify the most and least viscous liquids based on which traveled the fastest or slowest. Additional questions explore defining viscosity and comparing liquid flow to lava flow.

Activity 4. Viscosity race
Objectives: determine the viscosity of some liquids; and
describe the flow of gas in different liquids
Materials:
 four pieces of cone  drinking straw  syrup
out of a cardboard  tray  honey
 clear drinking glass  timer  cooking oil
 beaker  water

Procedure:
1. Before doing the activity, predict which liquid (water, syrup, honey, and cooking oil) takes the least
amount of time to reach the tray. Which liquid will take the most amount of time?________________
2. Place the cone marked A, B, C, and D on the tray.
3. Pour water on the top of cone A. Record the time it takes for the water to reach the tray.
4. Do it three times for each material.
NOTE: Use the same amount of material each time.

Q1. Is your prediction correct? ________________________________________________________________
Q2. Which liquid is the most viscous? How do you know? __________________________________________
__________________________________________________________________________________________
Q3. Which liquid is the least viscous? __________________________________________________________
Q4. Explain viscosity in your own words. ________________________________________________________
__________________________________________________________________________________________
Q5. Compare how these liquids flow with how you think lava flows. Why do some types of lava travel faster
than others? _______________________________________________________________________________

6. Put 100 mL syrup in a clear glass.
7. Using a drinking straw, blow some air from the bottom of the liquid. Observe.
8. Repeat procedure 7 by blowing harder on the liquid. Observe.
Q6. Compare the movement of the liquid as the bubbles move on the surface. _________________________
