Students describe the importance of structural features that increase surface area in a coral reef habitat.  In this investigative instructional activity students quantify the impact of modifications on surface area in model...

Students interpret and analyze data.  In this middle school mathematics lesson, students conduct an experiment in which they investigate which solar collector, black, white, or silver, absorbs the most heat.  Students examine...

Students explore mathematical concepts, problem solving, and the ability to program in LOGO to test ideas about speed, acceleration, gravity, and slope when dealing with downhill skiing.

No graphing calculator? No worries, there's an app for that! Young mathematicians use an app to graph functions. In addition, they can also plot data points.

Students explore slope.  In this middle school mathematics instructional activity, students analyze and interpret graphs as they investigate slope as a rate of change.  Students use a motion detector to collect data as they...

Second graders develop an awareness of the power of their minds to work with visual images. All the activities in this unit help strengthen visualization that is an important tool or process in Geometry.

Pupils explore scientific graphs and charts. They describe the origin of power curves and examine QC procedures. Students calculate critical-size errors that are medically important. They read OPSpecs charts. Pupils describe the...

Students explore the EasyData.  In this secondary mathematics instructional activity, students investigate the screens, menus, and  list of types of data collection available with the EasyData. 

Students estimate geographic position based on speed and air travel.  In GPS lesson students use GPS to estimate the set and drift of currents. 

Students investigate simple linear functions by trying to guess a function rule from inputs and outputs. They write the function rule in algebraic form.

Young scholars use data from the Rossi X-ray Tiiming Explorer (RXTE) satellite to analyze and graph.

Students identify effects of treatment weather on behavior of a wildland fire. They view simulation game that predicts effects of forest management on fire behavior.
