# New Math Module: Could These Bones Be Amelia Earhart's?

One of the many math resources we provide is a growing collection of math modeling modules students and teachers can use in class. We have a fun one this month! Students will determine whether a set of bones found on Nikumaroro Island might be Amelia Earhart's.

**Format of the Module**

This module includes four activities that guide students in developing a model for predicting human stature from bone lengths by:

- Working with a model that predicts height from tibia length
- Making a scatterplot of height versus forearm length from the class data
- Leveraging data from the Forensic Anthropology Data Bank at the University of Tennessee on height and bone lengths
- Using the coefficient of determination, a measure of the strength of a linear relationship

Once the activities are complete, students use their models and data on the bone lengths found on Nikumaroro Island to determine whether the bones might be Amelia Earhart's.

**Materials Needed**

To complete this math module, the materials needed are:

- Meter sticks, rulers, or tape measures with option for measurements in centimeters (Activity 1)
- Graph paper (Activity 2)
- Graphing calculators or computer software such as Excel, Desmos, GeoGebra (Activities 3 and 4)

**What’s Included**

Along with the four guided activities, this math module includes:

- Preliminary reading
- Lesson notes
- Activity answers
