Graphs of Exponential Functions
What does an exponential pattern look like in real life? After viewing a video of the population growth of bacteria, learners use the real-life scenario to collect data and graph the result. Their conclusion should be a new type of graph...

Himalayan Herds: Fractional Exponential Growth
Students solve problems by identifying exponential growth and decay and differentiating between patterns, relation and functions. For this algebra lesson, students apply concepts of exponential growth to solve problems.

Exponential Decay
I just bought that car, how can its value decrease already? Individuals use the data of a depreciating car value to create an exponential decay model. They then compare exponential decay and growth equations.

In the Billions and Exponential Modeling
Modeling population growth gives learners an opportunity to experiment with real data. Comparing the growth rates in this real-life task strengthens learners' understanding that exponential functions change by equal factors over equal...
Curated OER
Equal Factors Over Equal Intervals
Exponential functions and their growth rates are explored concretely using tables in a collaborative task. Then the successive quotient is explored algebraically.

Some Similarities Between the Spread of an Infectious Disease and Population Growth
Students compare and contrast the spread of infectious diseases and population growth. In this biology instructional activity, students identify the exponential growth pattern of spreading diseases. They relate this to HIV infection and...

Food Safety Lab
Students use the scientific method to investigate the role of temperature in microbial growth. In this food preservation lesson plan, students set up an experiment with fruit in room temperature and in a refrigerator. They record the...
Curated OER
Carrying Capacity of Ecosystems
Students define population and carrying. In this algebra lesson, students explore exponential growth and decay based on animals and things that grow or decrease exponentially. They graph their findings and discuss their results as they...
