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...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

Students examine the ways that populations become diverse and how mutation changes the diversity of a population.  In this exploratory instructional activity students study natural selection by completing a lab activity and discussing...

Bring together a study of two major scientific topics with a lesson on the relationship between pollution and evolution. With the help of a PowerPoint presentation, hands-on activity. and class demonstration young scientists learn how...

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...

Young ecologists explore the Aswan Dam in Egypt via the internet. Each collaborative group is assigned a specific article about the ecological impact of the dam. Then they prepare a presentation to share with the rest of the class. Some...

Students design an investigation using yeast. In this environmental engineering lesson, students design an investigation to determine how environmental factors affect the growth of yeast. They will collect quantitative data and discuss...

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...

Display a stunning drawing of the Gulf of Mexico's ecosystems. Learners examine the picture to determine what birds live there and what foods they rely on. Then show a poignant five-minute film that examines the impact of the 2010...

What makes a watershed? What are the natural and human features of a watershed? How do human features affect watersheds? Where can I find my local watershed? These questions are thoroughly explained in an informative watershed interactive.
