After analyzing the data, students make the
claim that traffic noises cause sparrows to sing
at a higher pitch. They back this claim with
evidence demonstrating that sparrows in areas
with more traffic noise sing at a higher pitch
than sparrows in areas with less traffic noise.
Research shows that singing at a higher pitch
leads to lower birth rates in sparrows. Students
then take this information to their community
to make the case that traffic noise is an
important problem to tackle. Students learn
complex communication and social skills
