Water, Corn syrup, cooking oil
Follow these steps to complete the model:
Build an inclined ramp. Use the cookie sheet as the ramp by placing one of its ends on top of the block or stack of books. Use the metric ruler to ensure that the height is 4 centimeters.
Use a stopwatch to measure the time it takes for each of the three liquids to travel down the inclined ramp in seconds. Use 5 mL (one teaspoon) per trial. Clean the surface with paper towels between trials. Complete three trials for each liquid and record your data in part A.
Part A
After completing three time trials for each liquid, enter the results in the table.

Calculate the average time separately for each liquid. To calculate average time, add the three times and divide by the number of trials.
Calculate the average flow rate for each liquid: distance traveled (cm) ÷ average time (sec). The distance traveled is approximately the length of your cookie sheet in centimeters. One inch is about the same as 2.5 centimeters.
Give each liquid a relative viscosity rating: low, medium, or high.
