1. One member of the group should serve as the timer, another should operate the table, another should record the results, and the fourth member is responsible for placing the structures on the table. 2. Start the table at speed # 2 and continue for 20 seconds. Increase the speed to # 3 for 20 seconds and continue with 20 second periods at higher speeds until the house falls. 3. The recorder should write as many observations in the table as possible. 4. Record the total number of seconds at the time the house falls or is broken. See the data table on the next pages. 5. For each house plot the time for destruction on the horizontal axis and speed on the vertical axis. Use a different symbol for each plot. Collect data from the entire class and plot on the graph. Safety TOUCHING THE MOTOR OR MODULATOR WITH WET HANDS. Time Type of House Speed or Damage Description (sec.) Sand?
