Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...

Tasmanian devils are scavengers who eat dead animals including the bones and fur. A video begins with cancer in Tasmanian devils to demonstrate the importance of genetic variation. Then examples such as the black-footed ferret and AIDS...

In this algebraic functions activity, learners write a function to determine the relationship between people and barrels of oil used. They research the population of the 10 largest cities in their state and use this functional...

State the population of the state. Pupils research census data on the total population, the number of children their age, and the number of children of the same age and gender in their states. They write these numbers in standard,...

Nobody is too old to learn something new. Young statisticians analyze census data on the percentage of the population older than 65 years old in US counties. They fit a normal distribution to the data, determine the mean and standard...

America is a country on the move. Analyzing data from the Census Bureau, class members gauge the people moving in and out of their areas. An interactive web feature allows pupils to see who is moving out and moving in, while discussion...

Keep track of a state's population. After a brief discussion on how population data is used for funding, individuals look at population changes over time. Pupils find the population of two states using three different censuses. They then...

Working in groups, learners research four countries' populations over the past 30 years. Using the data collected, the teams find regression equations that best fit the data. Taking the regression equations, they then make predictions...

Using technology, pupils find an exponential function to model the population growth of the US. With more information, learners derive the population growth formula for the world. Ultimately, they determine the amount of protein needed...

How do populations grow and change? Scholars define demographics and identify trends in human population growth and learn how to make predictions about population size based on data analysis. Learners then explore the concepts of age...

Statistically speaking, the content covers several grades. Featuring all of the statistics typically covered in a college-level Statistics course, the expansive content spans from sixth grade on up to high school. Material comes from a...

Graph growth in the US. Given population and area data for the United States for a period of 200 years, class members create graphs to interpret the growth over time. Graphs include population, area, population density, and population...

How do populations interact with one another? Identify the different types of interactions and how population sizes fluctuate and affect one another using an interesting PowerPoint presentation. Learners explore real-world examples of...

So that is how they do it! Pupils and teachers see how College Board assesses topics using the free-response questions from Form B of the 2007 AP® Statistics test. The six questions are divided in two sections, the first five being more...

To know what is on the test would be great. The six free-response question from the second form of the 2008 AP® Statistics gives pupils an insight into the format and general content of the exam. Each question requires the test taker to...

One size fits all doesn't seem to be the right approach to endangered species. Using a four-part AP® assessment, learners respond to questions that address environmental concerns such as human population changes, invasive species...

There is a strong correlation between the carbon dioxide concentration in the air temperature. Scholars offer explanations for the correlation in one of four AP® free-response assessment questions. Their analyses in the other questions...

Salmonella poisoning impacts over 200,000 people in the United States each year. Scholars learn about the growth of these bacteria using multiple approaches. Then they apply the same growth calculations to endangered species and think...

How have urban planners tried to attract people to cities? What can be done about booming birth rates in some parts of the world? How does a country's political structure affect the well being of its people? Scholars investigate these...

What is the appropriate model? Sample problems show the extent of the Smarter Balanced assessments Claim 4, Modeling and Data Analysis. Items provide pupils the opportunity to use mathematical modeling to arrive at a reasonable answer....
