A Little Devil In Need of Help
Math modeling to help endangered species? Scholars first investigate linear and exponential equations and graphs that model fictitious animal populations. They consider how key features of the graphs relate to the situation. As a final...
Curated OER
Population Patterns
Students study patterns of population growth in an ecosystem and why populations must remain in balance. They interpret basic population graphs and suggest scenarios about different population growth patterns in an ecosystem.

Exponential Functions -- M&M Activity
Students receive cups and M & M candies. They perform an experiment to compare the graph of theoretical and experimental exponential growth. Students spill a pair of candies onto the table. They add candies for each "M" they see....
Curated OER
Exploring Quadratic Equations
By stretching and translating the parabola given and determining the effects on the equation, students explore finding the vertex and zeros of a parabola and relate them to the equation. Students also view the intercept form to determine...

Modeling Population Growth
Students create linear, exponential, and quadratic models of U.S. population data to determine which function best represents U.S. population growth. They predict future populations based on each model.
Curated OER
World Population Study
Students explore an exponential relationship and how it relates to human population growth and the current global population crisis. They graph both exponential and linear information.
Population Connection
The Peopling of Our Planet
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...
Curated OER
Population Biology - Biology Teaching Thesis
Students explore the effects of different density-dependent and density-independent factors on population growth. They explore how the interactions of organisms can affect population growth. Students explore the pattern of population...
Curated OER
Bacteria and Illness
Students research information on bacterium and their relationship to food borne diseases. In this science lesson plan, students complete internet research to construct and analyze the growth cure of common bacterium and food-borne...

The Good, The Bad, The Ugly
Sixth graders examine the causes of the stock market crash of 1929. For this integrated math/history unit on the stock market, 6th graders study, research, and read stocks, visit a local bank, and create a PowerPoint to show the...
