viscosity races

Aim to test the rate at whitch different fluids flow.

materials needed

A stop watch



A Materials needed



tape measure



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



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



Small containers



Pencils



Recording table/sheets



A plastic drop cloth of catch the mess



Calculations

method

1 meausure out 30mls 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 you tip the liquid.


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 next test.


8 tip one liquid down the ramp and time how long it takes to reach the botte.


9 record your resalts in the table.


10 repeat for each type of liquid, recording your resalts as you go.


11 record each group resalts as they become avalible.


12 using the calcution, determine the mean distance and speed for each liquid.
