Whelk-come to Mathematics: Conduct an Experiment

Description:

Sea gulls and crows feed on various types of mollusks by lifting them into the air and dropping them onto a rock to break open their shells. Biologists have observed that northwestern crows consistently drop a type of mollusk called a whelk from a mean height of about 5 meters. In this lesson, students use rational functions to investigate the behavior of Northwestern Crows.

Minor Correlation

Common Core State Standards for Mathematics (2010)

High School — Statistics and Probability^★

Interpreting Categorical and Quantitative Data

Summarize, represent, and interpret data on a single count or measurement variable

Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers).

Broad Correlation

High School — Statistics and Probability^★

Making Inferences and Justifying Conclusions

Make inferences and justify conclusions from sample surveys, experiments, and observational studies

Use data from a sample survey to estimate a population mean or proportion; develop a margin of error through the use of simulation models for random sampling.

Statistics and Probability

Investigate patterns of association in bivariate data.

Use the equation of a linear model to solve problems in the context of bivariate measurement data, interpreting the slope and intercept.
