The "Bottled Bacteria" activity instructions are a bit unclear, but the remaining activities investigating limiting factors in ecosystems are well-written. Learners model the exosystem of a bear and a herd of deer. They set up a...

How does a population's habitat determine the size of that population? Teach learners about carrying capacity and limiting factors with an engaging roleplay activity. Class members pose as a colony of penguins who must gather food amidst...

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 watch a video on population dynamics. They conduct an experiment where they fill up a designated space with students. They recreate multiplying rabbits using beans.

Young scholars use scientific methods to investigate the effects of overpopulation of seed plants on growth in a limited living space. Students relate seed plant population findings to that of other organisms.

Students compare and contrast the spread of infectious diseases and population growth. In this biology lesson, students identify the exponential growth pattern of spreading diseases. They relate this to HIV infection and AIDS.

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.

The way you use statistics can tell different stories about the same set of data. Here, learners use sets of data to determine which person sends the most text messages. They use random sampling to collect their data and calculate a...

Students study and analyze data collected on the relationship between the snowshoe hare and lynx in Canada over a 28 year period and create a graph. Students also write a response to a proposal to reduce the lynx population.

Young scholars are introduced to the seed cycle and draw the specific steps. In groups, they identify the human barriers to the spreading of weeds. After calculating the rate of spreading of the Yellowstar Thistle, they create graphs to...

Students research information on bacterium and their relationship to food borne diseases. For this science lesson plan, students complete internet research to construct and analyze the growth cure of common bacterium...

Seventh graders create a model of an ecosystem and label it to show structure and function. They research the food web of an aquatic animal and also trace energy flow from the primary producer up the food chain.

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...

Middle schoolers examine the role of large families in some animal populations. They work together to complete an activity related to food supply. They discover the relationship between preys and predators.

Young scholars define population and carrying. For 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...

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...

Students discover how environmental factors impact the survival of a population. In this landscape design lesson, students create a new animal and discuss the relationship between the animal and its environment before creating a habitat...

Students watch video clips of ecosystems and answer questions relating to them.

Learners investigate Canadian people by researching the geography of the country.  For this world geography lesson, students identify locations within Canada with large populations based on their access to waterways.  Learners...

Students compare and contrast abiotic and biotic factors. They discuss how these factors effect ecosystems. They answer questions to complete the lesson.

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...

Fourth graders compare and contrast the businesses in Fort Griffin with those in their own community. Using the internet, they discover the factors that have influenced the development of businesses in a town. They also create a map of...

Students explore the basics of ecology through numerous hands-on and relevant activities. They participate in an online food chain demonstration, which explores food web dynamics. They dissect owl pellets, examine the prey's bones, and...

Students play a game in physical education class to examine how a deer survives. Using nature as a guide, they discover how it is constantly changing due to weather, food, water, pollution and predators. They discuss the characteristics...
