Mathematical Modeling: Lesson 1
Will more deer result in more big game licenses? Scholars first research data on the number of deer and the number of big game licenses in Virginia between 1990 to 2009. They apply polynomial, exponential, and logarithmic regression to...
Radford University
Mathematical Modeling: Lessons 2-3
Not all functions are created equal. Pupils apply regression analysis using polynomial, exponential, and logarithmic functions to investigate the relationship between variables and to decide which function would be best to model the...

Body Measurement Activity
Don't keep the resource at an arm's length. A hands-on activity has scholars measure the heights, arm spans, hair lengths, and foot lengths of their classmates. They create scatter plots to determine if there is a correlation between...
Radford University
The Normal Distribution Activity
For whom does the bell fit? Pupils begin by working in groups gather data on three different variables. They then determine the mean and standard deviation of each data set and create bell curves. To finish, they answer guiding questions...
Radford University
Exploring Types of Variation Activity
Create a variable list of problems. Groups come up with four scenarios. Each situation represents different types of variation, direct, inverse, joint, and combined. Teams then generate questions about their contextual problems for...
Las Cumbres Observatory
Star In a Box
Stars may all look the same from down here, but their surfaces tell a different story. Using an animation, learners collect data about the temperature and luminosity of stars and compare them to their mass and radius. They then answer...

Titanium Dioxide Raspberry Solar Cell Data Sharing
Concerned about how well others did on the experiment? Scholars share results from the titanium dioxide raspberry solar cell test they performed in the previous lesson. After analyzing the data, they come up with a claim about the...

Nonlinear Modeling: Something Fishy
There are plenty of fish in the sea, but only a few good resources on regression. Young mathematicians first perform a linear regression analysis on provided weight and length data for fish. After determining that a linear model is not...
