Insects threaten the food production industry, and aphids are one of the big players! Analyzing data of aphid populations gives insight into their behaviors. Learners model the population data of an uninhibited population with an...

Here learners get to flex some serious algebraic muscles through an investigation of logistic growth. The properties of the constant terms in the logistic growth formula are unraveled in a short but content-dense...

Learners explore data that be modeled by a logistic function. They have the opportunity to study real-life data and create a mathematical function to model the data and make a prediction.

Young scholars explore the various uses of the logistic function. Students use the internet to collect world population data and find a logistic model for their data and use their chosen model to predict future populations.

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...

In this population worksheet, students read word problems relating to population growth. They write the problem as a differential equation, create models and graphs of the solution. This three-page worksheet contains 10 multi-step...

The clear cartoon style slides in this presentation contain details that affect population growth. Natural disasters and other external factors are listed as density independent factors, and density dependent factors, such as competition...

Students view a documentary, read articles, discuss and write about Europe's struggle with strained U.S. relations, increased terrorist activity, a growing Muslim population and the logistics of uniting under the European Community.

Students use the data from USA TODAY Snapshot "World population milestones" to explore and explain the trends in the world population.

Students examine the significance and effects of outsourcing jobs to India and Malaysia. They conduct Internet research, create a map and a timeline, write an editorial of their view on the use of outsourcing, and participate in a class...

Students view a video on AIDS, HIV and the ways in which HIV is spread. They discuss ways to avoid contracting HIV and participate in a simulation that shows the growth of a communicable disease.

Twelfth graders solve problems using differential equations.  In this Calculus lesson, 12th graders analyze data regarding the spread of a flu virus.  Students use the symbolic capacity of the TI-89 to develop a model and...

Students investigate the real world applications of nutrition. They study the problem of starvation and how it affects different populations. Students work in small groups in order to devise and intervention plan. They also search out...

Students investigate wind and weather by creating a weathervane.  In this environment lesson, students identify the purpose of a weathervane and observe weathervanes in action on their campus.  Students create a weathervane and...

Middle schoolers identify long and short term goals. In this perseverance lesson, students discuss the difference between short term and long term goals. Middle schoolers categorize their personal goals as short or long term. Students...

For this task, students are presented with an equation for a logistic growth model and are asked to analyze it. They are then questioned about a graph showing bacterial population growth. Next, they must use information from earlier...

For this task, students are presented with a graph showing the growth of the U.S. population from 1790 to 1940 and are given the equation for a logistic function for it. They are asked to use the equation and the graph to find the...

In this task, students are shown a table of population data for the city of London and are asked to explore whether a linear, quadratic, or exponential function would be appropriate to model relationships within the data. They are next...

The proper inspection machining or refinishing of disc brake rotors ensures quality brake repairs with little to no opportunity for returns for customer complaints. This lesson will teach inspection, measuring and machining techniques...
