viscosity races

investigate the flow of liquid


Aim: To test the rate at which different fluids flow.


my prdiction is this inverstigation will let me know viscosity of each liqud or thng we use

Materials needed

A stop watch

A tape measure

A ramp – a table and two trays (secured with masking tape).

30 mls of each different liquid to test (water, oil, sauce, honey, and mayonnaise)

Small Containers


Recording tables/sheets

A plastic drop cloth to catch mess



1. Measure out 30 mls of each liquid.

2. Set your stop watch to zero

3. Tip one liquid at a time from the top of the ramp. Remember to communicate with your group to ensure the timer starts as the liquid tips.

4. Let the liquid flow for the set time you have decided and measure the distance travelled.

5. Record your results in the table

6. Repeat for each type of liquid recording your results 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 get to the bottom.

9. Record your results in the table

10.Repeat for all types of liquids recording the results as you go

11. Record each groups results on your table once they are available

Using the calculator find the average for speed and distance
