pH and Macroinvertebrate Populations - Do Changes in the pH Level Effect an Aquatic Ecosystem?

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...

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...

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...

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

The fourth activity in a series of five has classes participate in a jigsaw to learn about global impacts of climate change and then share their new information with a home group. Groups then research impacts of climate change (droughts,...

Every species in the world has some type of relationship with another species, whether it be positive, negative, or neutral for each party. Mr. Andersen defines each type of relationship and provides clear examples under each category....

Why do most populations remain stable over time? Usually it is a result of either environmental resistance or carrying capacity. Examine some of the factors that help stabilize animal populations, and explore some of the changes that...

Students research abiotic and biotic factors concerning the concept of an ecosystem. Record and analyze data collected. Write a lab report in proper and scientific format with thinking and analytical skills. Work as a cooperative team.

A video about the impact of climate change on butterfly populations and a PowerPoint about butterfly and bird adaptations warm science learners up for the activity to follow. Using a variety of tools that reprsent unique styles of bird...

Pair earth scientists up to use an amazing online arctic portal mapping tool and Google Earth to analyze permafrost changes. They compare changes to data on atmospheric concentrations of methane to see if there is a correlation. Then...
