## Power to the Variable

CertifiedStudents will model the data with both a linear function and an exponential function and use it to predict the CO2 concentration in the year 2050 and also when the CO2 concentration will be above 500 parts per million. Students will discuss and document which model makes a better prediction and...

## Printing Yearbooks

CertifiedStudents will choose the best option for a yearbook under the given conditions. They will analyze pricing from different yearbook companies and narrow their choices to three. They will create models and use these to solve the task algebraically and graphically. They will create a presentation...

## Modeling Periodic Functions

CertifiedIn this task, students will investigate a periodic phenomenon in the world and propose a mathematical model that demonstrates the phenomenon. Upon completion of the project, students will submit a poster or a written report demonstrating the periodic phenomenon investigated. A 5-6 minute...

## Cooling Project

CertifiedThis task uses a new product, Joulies, which claims to help keep hot drinks hot longer. Students will study the change in temperature of an object as it cools and model its temperature as a function of time and use their knowledge of Algebra 2 in order to build a mathematical model of a cooling...

## Honey Bee Colony Analysis

CertifiedIn this task, the students mathematically model changes in the bee colony numbers from the United States and from two individual states, California and South Dakota.

Students then use their constructed mathematical models to describe factors affecting the bee colony populations. The...

## Sleep Deprived

CertifiedThis task is an opportunity for students to apply their statistical reasoning to a relevant social and health issue: the importance of sleep. This task focuses on the use of the normal distribution as a mathematical model and on formulating a question, gathering data, and answering a key...

In this task, students will be asked to write an article about how the cost of education has increased over time.

Students will be required to create scatterplots and graphs that demonstrate their knowledge of linear equations to use in their article. They will also be turning in their...
