Title: Analyze the Data
Description: In this lesson, one of a multi-part unit from Illuminations, students use rational functions to investigate the feeding behavior of Northwestern Crows. Biologists have observed that northwestern crows consistently drop a type of mollusk called a whelk from a mean height of about 5 meters. By analyzing a data set, students investigate and create a model for the relationship between the height of the drop and the number of drops.

Title: Work to a Conclusion
Description: In this lesson, one of a multi-part unit from Illuminations, students use rational functions to investigate the feeding behavior of Northwestern Crows. Biologists have observed that northwestern crows consistently drop a type of mollusk called a whelk from a mean height of about 5 meters. Students develop a model for finding out between what heights the amount of work is the smallest. Students then use an interactive applet (or their own graphing calculator) to explore the rational functions related to this investigation and to find the height corresponding to the minimum work.

Title: Light It Up! Activity Sheet
Description: This reproducible activity sheet, from an Illuminations lesson, describes the game '' Light It Up,'' the object of which is to slide a laser pointer so that when the beam is reflected off a mirror, it hits a target that is 1 m off the ground. This activity sheet provides background information about the game along with activities that enhance understanding of rational functions, which is needed in order to correctly position the laser pointer.

Title: Whelk-Come to Mathematics
Description: In this four-lesson unit, from Illuminations, students make a conjecture, conduct an experiment, analyze data and work to a conclusion using rational functions to investigate the behavior of Northwestern Crows. 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. Students investigate the relationship between the height of the drop and the number of drops.

Title: Northwestern Crows
Description: In this lesson, one of a multi-part unit from Illuminations, students use rational functions to investigate the feeding behavior of Northwestern Crows. Biologists have observed that northwestern crows consistently drop a type of mollusk called a whelk from a mean height of about 5 meters. Students investigate the relationship between the height of the drop and the number of drops by viewing a video clip; then, they plan a classroom experiment to model the dropping of whelks in order to collect and analyze data.
