In this activity, student teams create a knowledge map of the essential characteristics or factors of a planet with a habitable climate, identifying range of inputs, outputs and variables of a planetary environmental system. Identified... (View More)

Students will time the flow of water through soils with different properties and measure the amount of water held in these soils. They will also experiment with the filtering ability of soils by testing the pH of the water before and after it passes... (View More)

This learning activity engages students in measurement of pH in water and soil samples, plants and other natural materials. By mixing different substances, they observe how pH changes, and become familiar with the pH of common household products.... (View More)

In this introductory classroom activity, students exercise their scientific skills of observation and deduction as they use their senses and simple laboratory assays, such as pH indicator paper, to identify mystery pollutants in water samples.... (View More)

In this lab-based activity, students learn how to use scientific instruments used to take hydrological data. Students will rotate among measurement stations for each of the hydrology protocols that will be done by the class. They will practice using... (View More)

In this hands-on experiment, students will investigate the basic principle of photosynthesis and learn how light intensity diminishes as a function of distance from the light source. Questions help learners connect these two ideas to determine if... (View More)

The activities in this investigation train students to differentiate between physical (natural) and human-made features. Using both space shuttle photographs and satellite images, students will identify some of Earth's prominent natural and... (View More)

This investigation teaches that physical and human features are used to characterize places on Earth. Since types of both features are visible from space, students will use NASA images to complete several activities: matching images to geographic... (View More)

Nighttime light patterns on Earth have been recorded using NASA satellites. In this investigation, students will correlate those patterns of lights with the distribution of human populations, and then determine if related statements included in the... (View More)
