This article describes an approach designed to decrease math anxiety and teach students about the use of mathematical symbols simplifying radicals. A deck of cards is used in a demonstration, and a problem set using real life examples to master the... (View More)

In this activity, students learn about the changing configuration of the continents over geological time resulting from plate tectonics. Using a map pair, students measure the difference in distance between continents 94 million years ago and today,... (View More)

This is an activity about comparing images of the Sun in different wavelengths of light. Learners will examine solar images taken by the SOHO spacecraft to look for differences in the features that are visible in the various wavelengths of light.... (View More)

Audience: Informal education

Students explore how mathematical descriptions of the physical environment can be fine-tuned through testing using data. In this activity, student teams obtain satellite data measuring the Earth's albedo, and then input this data into a... (View More)

In this learning activity, students will construct a soda-bottle thermometer, which is similar to the thermometer used by GLOBE schools. Both are based on the principle that most substances expand and contract as their temperature changes. This... (View More)

In this activity, students produce a land cover map of a 15 km x 15 km GLOBE study site from hard copies of Landsat satellite images. Students place clear transparencies over the Landsat TM images and use markers to outline and classify areas of... (View More)

In this activity, students quantitatively evaluate the accuracy of a classification and understand a simple difference/error matrix. Students sort birds into three possible classes based on each bird’s beak: carnivores (meat eaters), herbivores... (View More)

This is a lesson about the distance to Saturn. Learners will use simple props to create a playground model for size and distance for the Sun, Earth, and Saturn — then walk on their scale model to Saturn. Writing activities engage students in... (View More)
