Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

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.

Students solve problems by identifying exponential growth and decay and differentiating between patterns, relation and functions. In this algebra lesson, students apply concepts of exponential growth to solve problems.

How can you model exponential decay? Explore different situations involving exponential decay functions and decreasing linear functions by performing activities with MandM candy, popcorn kernels, and number cubes.

Young scholars investigate oral hygiene.  For this personal health lesson, students discover the parts of a tooth and how to best protect them from disease.  Young scholars examine the effects of acids on tooth enamel and calcium.

Students investigate the different hormone contaminants in the water supply. In this math lesson, students analyze data tables and graphs. They demonstrate exponential growth and decay using frog populations.

Your algebra learners write linear, exponential, and quadratic equations containing the same two graph points in this collaborative task.

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...

Students use the scientific method to investigate the role of temperature in microbial growth. In this food preservation instructional activity, students set up an experiment with fruit in room temperature and in a refrigerator. They...

Pupils visit a local park to test the quality of the aquatic environments. They search for sources of pollution and examples of pollution control. Based on their obeservations and experiments, they rate their local environment.

In this task, students are shown a table of U.S. population data between 1790 and 1860 and are asked to explore whether exponential functions would be appropriate to model relationships within the data. The purpose of the task is to help...
