Salmonella poisoning impacts over 200,000 people in the United States each year. Scholars learn about the growth of these bacteria using multiple approaches. Then they apply the same growth calculations to endangered species and think...

Life has its ups and downs ... especially if you're an animal! Biology scholars engage in a population study through an inquiry-based lesson. Pupils work together to explore the factors that affect deer populations, then examine the...

Students define the following terms: predation, competition, carrying capacity and population. They can explain the patterns of growth and the limitations of growth. Students explain the difference between density-dependent and...

As the reality of population decline across many species becomes real, pupils learn about the variables related to changes in populations. They complete a simulation of population changes and graph the results, then discuss limiting...

Learners 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...

Collaborators sort a set of cards into biotic and abiotic categories. Then, as a class, they discuss their work and relate each of the abiotic components to climate change. Finally, they form a web of components by connecting those that...

New roads, new businesses, new developments, new mass transit systems. All growth has both positive and negative effects on communities. Government classes investigate the principles of Maryland's 1997 Smart Growth program and...

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...

Have you always wanted to take your science class on an amazing field trip they will never forget? Now you can! Observe the wildlife in an African savanna through trail cameras with a five-part data analysis activity. Learners analyze...

Students explore the biotic and abiotic factors that affect plant reproduction and the potential consequences of human activities on plant populations. The effects of urbanization are discussed as an influence in the consequences.

What are the factors that influence voting patterns? How do these factors influence government funding? Is participation the squeaky wheel gets the grease? Class members interpret graphs and analyze trends to determine what...

Tenth graders are introduced to the process of succession and gain awareness of the changing nature of ecosystems. They demonstrate a comprehension of the dynamic nature of ecosystems, including the relationship between ecological...

Approximately 50 percent of people in the world who are chronically hungry work in agriculture. While it seems counter-intuitive, the farther you live from a farm, the more food options are available. Scholars explore concepts related to...

Students investigate the growth of yeast in a sugar solution. They verify the pressure of carbon dioxide using bromothymol blue. Students are asked to describe the difference between the contents of the test tubes used and to explain...

Students are introduced to the concept and components of a habitat. They discuss the key components of a habitat and describe how certain factors can cause disturbances in a habitat and change its population. Activities are leveled...

Students are able to describe the reproductive cycle of the gopher frog. They are able to describe the impacts of habitat loss and degradtion on gopher frog populations. Students are explained that many factors limit the survival of...

Learners are introduced to the concept and components of a habitat. They discuss the key components of a habitat and describe how certain factors can cause disturbances in a habitat and change its population. Activities are leveled for...

Young scholars utilize an interactive map to explore the 1858 Senate campaign in Illinois. They examine how factors such as population, transportation, and party strongholds can affect campaign strategies. Students write an essay...

Sixth graders study the important habitats, flora, fauna, and physical factors of coastal habitats. They compare the aquatic habitats to terrestrial habitats by researching and completing tables with the information.

Students hike a local mountain and examine its life zones. They measure various components at each zone and collect leaf litter at the sites. At the mountain top, students make descriptive observations and complete a handout about the...
