The emperor penguin actually holds the world's record for the deepest dive by a non-flying bird. The data table (below, left) lists the penguin's record. It also shows the maximum diving depths of other animals. First, calculate to convert the diving records from feet into meters (Hint: 1 foot = 0.305 meters). Be sure to round up to the nearest whole number. Then, use your calculated metric measurements to complete the bar graph (below, right). DIRECTIONS: Study the chart and graph to answer the questions below. Use complete sentences. 1. According to according to prep. 1.
