Teacher Reflections
After our visit to Professor Ratilal’s lab, we took the train back to school. We decided to listen to people in the train, and noticed that the noise level was similar to that of our school. That was when students came up with the idea to observe a few minutes of silence, sparingly, during each class period. Some students describe this silent time as scary because they are not used to it. Many students have stopped popping their chewing gum, some are not chewing it any longer, and we no longer have problems with cell phones. I have not heard a game boy played in class for a long time . . . . This project motivated students, especially the young women, who did not see connections between math and health science careers. It also opened eyes and ears to noise pollution.

Student Reflections
Women in Science Careers involved research, presentations, and a visit to Northeastern University. The Professor was a female and so were her assistants. The laboratory deals with acoustics technology related to medicine and warfare. Professor Ratilal discussed the importance of waves, and showed how to calculate them. She also showed how seals use sound waves to travel. She demonstrated that a wave records popping gum, clapping hands, etc. Through measurements done in the laboratory, we realized that noise pollution, like loud music, echoes and vibrates. Other individuals or organisms can pick them up. They also may disturb the ecosystem. . . . Since our visit, students have come to respect people’s space and to learn about other uses of sound waves.
