Students explore how GPS works, the mathematics behind the technology, and how GPS is used. They find positions in one and two dimensions, and participate in a WebQuest that explores how math is used to find a location on Earth using GPS.

Students examine the possibilities of communication with other living organisms within our solar system through research and hands on activities, as well as observing and analyzing teacher demonstrations.

Learners record data, make observations, and share in experimentation and discussion of numerical experiments.

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.

Young scholars build a model of their school playground. They view models from the classroom (such as a globe, doll house, or cars). Students share observations about the models. They use a paper mat to represent the playground and use...

Learners use standard rulers to measure the length of common classroom items - such as pencils, books, desk tops - in inches and centimeters, and measure weight in pounds. They also answer math questions, such as "How long is the front...

Eleventh graders practice the Quadrat Survey Technique to analyze the biodiversity of a local plant community. They compare its biodiversity with the documented changes in biodiversity of the tallgrass prairie over time.

Middle schoolers chart temperatures in Egypt on spreadsheet to determine how weather conditions affect lifestyles.

Students use yearly averages over a five-year period to understand weather trends for a specific area.

Third graders create a model of the solar system. In this solar system lesson, 3rd graders create a scale model of the solar system. Working in pairs students solve mathematical problems to correctly measure the distance each planet is...

Students construct a simple spectroscope. They observe the emission spectrum produce by a source of light.

Students are told that an air tank contains a fixed volume of air under pressure. As air is used, the pressure decreases at a rate that depends on the depth. Students discuss how SCUBA divers calculate the amount of time they can spend...
