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...

Learners explore a perspective application of the TI-73. In this middle school mathematics lesson, students view the front, back, right, and left views of a city to determine the height of each building in a city plan.

Learners use interactive geometry exploration software (GES) to create a two-point perspective drawing. They explore basic geometry concepts in and geometric transformations of the model of a rectangular prism viewed from different...

Students formulate a definition of tessellations by comparing and contrasting different patterns and shapes of real objects. They discuss the relatioship between shapes and patterns as well as their function in the real world. Students...

Students are introduced to the concept of aerial perspective and scale. Students will use satellite technology to view their neighborhoods and sketch the area surrounding their schools. They will take part in a neighborhood walk to view...

Students map and describe small area of the schoolyard and discuss habitats.

Upper elementary and middle schoolers explore the properties of various polygons. They use video, resource links, and engage in hands-on activities in order to construct geometric nets. This fine plan should lead to increased...

Students examine hurricanes. In this web-based meteorology lesson, students study the relationship between ocean temperature and hurricane intensity. They differentiate between intensity and frequency of hurricanes.

Students explore and analyze atmospheric conditions for a high mountain retreat. They examine the relationship between altitude, atmospheric pressure, temperature and humidity at a particular location. In addition, they write reports...

Students use data collected by an astronomer to determine the relationship between the time it takes the planet to orbit the sun and the average radius of the planet's orbit around the sun. Students use trial and error to find the...

Young scholars recognize the correlation between the trash they dispose of around their school and the environmental hazards that face wildlife, specifically the Laysan albatross. They determine three ways that they can help the...

Students watch video segments on shapes and patterns. They create their own pattern within shapes.

A collection of interactive visualizations that were produced through analysis of economic, political, and market research data. Topics are diverse, e.g., military spending and trade, immigration, consumer spending, crime, unemployment,...

This section explores how to design and conduct surveys that accurately reflect the perspectives of a larger group of people by identifying unbiased sample groups and by writing unbiased questions.
