Viscosity Races
By: Zain M. Siddqui
Aim & hypothesis
Aim: To test the rate at which different fluids flow
Hypothesis: The water will be the fastet and Mayonnaise will be the slowest
Materials Needed:
· Stop Watch
· A Tape Measure
· A ramp a table and two tote trays (secured with masking tape).
· 30 seconds of each different liquid to test (water, oil, tomato sauce, yogurt mayonnaise )
· Small containers
· Recording tables/sheets
A plastic drop cloth to catch the mess
· Calculators
Method:
1. Measure out 30mls of each liquid
2. Set your set your stop watch on zero
3. Tip one limit at a time from the top of the ramp. Remember to communicate with your group to ensure the time starts as you tip the liquid
4. Let the liquid flow for the time you have decided and measured the distance travelled
5. Record your result in the table
6. Repeat for step type of liquid, recording your result as you go
7. Clean your ramp for the next test
8. Tip one liquid down the ramp and time how long it takes to reach the bottom
9. Record your result in the table
10. Repeat for each type of liquid, recording your result as you go
11. Record each groups result as they become available
12. Using the calculator determine the mean distance and spread each liquid
