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...

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...

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...

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 define population and carrying. In this algebra lesson plan, 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...

Pupils use the internet to research the history of Fair Haven, Connecticut. In groups, they are introduced to the socio-economic developments and how the area has grown over time. They work together to create their own bridge design...

Eighth graders collect data from Bottle Biology compost columns and record using Excel spreadsheet.
