What does it mean for something to grow exponentially, and how does that compare to linear growth? This activity tries to help learners gain an understanding of these concepts while modeling real-world problems. Linear and exponential...

Build up from the previous activity where your learners charted the population growth and decay of a fish pond with M&Ms®. Have them look at the data from that activity and create a Now-Next, or recursive equations, to predict the...

Did you know that birth and life rates vary across the world? The resource, the second in a six-part series, discusses just how demographics differ across countries and why it might be the case. Scholars complete worksheets, watch...

Did you know that the population is expected to grow to 11 billion by 2100? The resource serves final installment in a six-part series on the global population and its effects. Scholars interpret data from the United Nations about the...

Skeeters are used to model linear and exponential population growth in a wonderfully organized lesson plan including teachers' and students' notes, an assignment, graphs, tables, and equations. Filled with constant deep-reaching...

Your young microbiologists will interpret and solve exponential equations in this real-world context task set in a hospital research scenario. Learners think in terms of the functions as well as their rates of change. 

In this real-world problem about the rapid growth of rabbit populations, students must analyze two different scenarios and create mathematical models to represent them. They use their exponential models to answer questions about the...

Use this twelve-day lesson plan to teach about the causes and courses of WWI. Each day scholars attend lectures, complete creative activities, and hold round table discussions on what they've learned. Web links and resources are...

How many people live on the planet, anyway? The first resource in a six-part series covers the topic of the world population. Scholars work in groups to conduct research and make population posters after learning about the global...

Carbon is in the air; should we care? Teach the class why it is important to pay attention to carbon levels and how the world population and various countries across the globe affect the carbon levels in the atmosphere. High schoolers...

Get your class out in the environment for hands on math activities. In this wetlands lesson, learners transplant native plants, calculate how much soil is needed, and perform math activities based on this experience. They then make...

Primary source research, secondary source readings, and discussion provide the understanding necessary for students to create a colonial persona, and simulate a situation appropriate for this person, time, and place. While the activity...

Introduce your mini-marine biologists to using databases. Tables of how many Chilean Sea Bass were caught and number of hours spent fishing are examined. Using the data, individuals calculate the "Catch per Unit of Effort" for each year....

Second in a series of five lessons, this lesson encourages preteens to consider cities as urban ecosystems. First, they keep a food diary for a few days. They visit the Natrional Agricultural Statistics Service website for current data...

Music, writing, and activism all tell the story of history! The resource uses these elements and more in a presentation to discuss the Jazz Age and Harlem Renaissance. Your class views biographies, discusses important events, and...

Every time you purchase something from the store, it goes into a bag, but what happens to the bag? This lesson encourages your learners to think about what happens to those plastic and paper bags and their effect on the environment. Use...

While incomplete, this lesson could provide ideas for a lesson on the California gold rush. Learners look at a chart to analyze population growth in San Francisco after the discovery of gold, analyze political changes that occurred, and...

An excellent series of five lessons on China awaits you and your young geographers. In these lessons, learners engage in hands-on activities, watch streamed video, access websites, and complete activities in cooperative groups in order...

Exponential growth is modeled by learners as they analyze and interpret the data presented in this real-life scenario centered on the destructive invasion of the Giant African Land Snail. Learners get a touch of history and practice...

Your young fishermen learn about exponential function growth by interpreting the pieces of the given equation within the context of numbers of fish in a lake.

Through a fishing simulation, environmentalists discover consequences of over fishing. Afterward, they discuss how the activity relates to the impact of real-life commercial fishing. They also consider sustainability in the fishing...

Youngsters examine how people show respect and care for the land. Specifically, learners see how the Native Americans truly did care for and respect the land, and still do so to this day! They also explore how they themselves can care...

Does where we live influence how our bodies express genetic traits? Explore variation in human skin color with an activity that incorporate video and hands-on learning. Individuals model the relationship between phenotypes and genotypes,...
