How Many Penguins Does It Take? Studying Carrying Capacity and Limiting Factors
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...

Population Dynamics
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...

Graphing Iron Data
Learners apply a data set to create a graph show how iron ore impacts an ecosystem. They explain how the iron effects the distribution and abundance of phytoplankton in coastal ecosystems using spreadsheet software.

Carrying Capacity of Ecosystems
Students define population and carrying. In 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 they...

Marine & Aquatic Habitats Activities - Marine Ecology
Students enact the life cycle of a sessile animal and quantify the possibility of survival under the conditions given. They then present to the class a new adaptation which will increase the animals chance of survival.
