Purring Crickets: The Evolution Of A New Song

(1 review)


Students will analyze data to determine if silent, “purring” male crickets are preferred over loud, “singing”, male crickets.

Each Data Nugget comes with three student versions, based on the type of graphing skills required. Type A activities provide the graph for the students (allowing a focus on graph interpretation, making claims based on evidence, and explaining reasoning), Type B activities provide axis labels but requires students to graph the data, and Type C provides an unlabeled grid on which to draw a graph.

This DataNugget is a follow up to two earlier research projects/Data Nuggets, which could be used together to show the progression of the research questions.

    Data Nuggets are free classroom activities co-designed by scientists and teachers that bring contemporary research and authentic data into the classroom. Each activity gives students practice working with “messy data” and interpreting quantitative information. Students are guided through the entire process of science, including identifying hypotheses and predictions, visualizing and interpreting data, making evidence based claims, and asking their own questions for future research.
    These three Nuggets show the progression of a research question over several years, as well as demonstrate observable natural selection. Together they will challenge students to figure out what is changing, and what effect is has on the survival and reproduction of these Hawaiian crickets.
