Do Dams Affect the Paddlefish Population?

How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases and...

Here is a lesson that includes many great ideas for investigating and discovering how our communities have physically changed over the years, and how land use changes over time may affect a community's water supply. The lesson's...

Find your niche in the science classroom. Learners study the role of niche populations within an ecosystem and consider the impact of the loss of these organisms. Their investigation includes vultures, honey bees, and mosquitoes.

How many of us can say they've seen a Pacific walrus? Not many and one of the reasons is the impact of climate change on their aquatic environment. Children get to think about the food web of the Bering Sea by creating an actual web with...

To begin the learning about dams, learners read (or are read to, depending on the age group) a passage about how dams work. Next, they work in groups to use the materials provided to build a small scale working dam. After the experience,...

Students explore biodiversity and populations using Alaska's wildlife as their focus. In this environmental statistics instructional activity, students examine the concept of exponential growth in a population and calculate the change in...

How diverse is the world we live in compared to the way things used to be? Young biologists explore diverse organisms and relate the structure of each organism to its ability to survive in our current environmental conditions....

A worksheet showing both historic and current ranges of mountain lion populations is given to emerging ecologists. They examine human population data as well and try to determine if there is any correlation. Critical-thinking questions...

Math and M&Ms® go great together when introducing a modeling activity. Allow your learners to simulate population growth and decay of fish in a pond and share their reasoning for the change in fish. With such an impact we have on our...

Elementary ecologists pretend to be migratory hummingbirds. They fly between wintering and nesting grounds, trying to reach a habitat haven. In a musical-chair fashion, some birds will miss out, and are removed from the game. To further...
