The Heart Stopper Data Table

Student Worksheet

Directions:

  1. Pump the bottle as many times as your heart beats in one minute in the inactive mode. Note any difficulty the pumper might have had.
  2. Collect the water in the beakers and measure it. Record the measurement.
  3. Insert the smallest (2mm) screw in the end of the short tube and secure it with a clothespin.
  4. Repeat steps one and two.
  5. Replace the screw, increase the size of the screw used, pump, measure the water output, and record the data until you have data for each sized screw.

Plot the amount of fluid (representing blood) that passes from your pump (representing the heart) through the tubing (representing the artery). Predict what will happen if an artery to the hear is slightly blocked while the artery to the rest of the body is not. _________________________________________________________________________
