Curated OER
Most Troublesome Exotic Invasive Plant Species Web Quest
Students participate in a Web Quest activity in which they identify common exotic invasive plant species of the Southern Appalachian Region. After identifying the top 10 exotic invasive species, they choose one to research in depth.
Curated OER
Hopskotch Migration
Students understand the use of the wetlands by migrating birds and identify causes for disappearance of the wetlands.
Curated OER
Bioremediation
Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.
Curated OER
Lichens as Air Quality Indicators: A beginning lichen identification study (2003
Students use GPS and trees to explore lichens and air quality.
Curated OER
Hopscotch Migration
Pupils examine the use of wetlands by migrating birds. They discuss reasons for the disappearance of wetlands. They discover how humans have affected wetlands as well.

Journal of Statistics Education: A Sample / Population Size Activity
The author of the article admits having had a difficult time in the past when getting students to understand that samples need to contain a substantial portion of the population. Here, an activity is detailed to bring this important fact...

Serc: Reese's Pieces Activity: Sampling From a Population
Students use Reese's Pieces to investigate the proportion of orange candies present in a set of 25. After collecting data for the class, they use a web applet to collect more data for random samples. This is compared to the actual...

Texas Gateway: Generalizing About Populations From Random Samples
Given a population with known characteristics, students will be able to use a variety of methods to generate random samples of the same size in order to understand how a random sample is representative of a population.

Texas Gateway: A Single Population Mean Using the Normal Distribution
This lesson explains how to calculate and interpret the confidence interval for a population mean. It also looks at the effect on the confidence interval of changing the confidence level or sample size. It then explains how to find the...

Texas Instruments: Central Limit Theorem
This set contains questions regarding the Central Limit Theorem. The student sees that, as the size n increases, the shape of the sampling distribution gradually approaches a normal curve, and its population standard deviation decreases.
