In this activity, students learn about hierarchical classification systems and create their own classification system for leaves they collect in the field. They learn about the key characteristics for classification systems and see that there are... (View More)

In this laboratory activity, students analyze soil samples from their homes to identify soil properties and learn about soil classification. Soils sampled by students from different environments are compared, and students ask questions about the... (View More)

In this hands-on activity, students create a model soil profile in a two-liter beverage bottle, time the movement of water through different soils and observe the amount of water held in these soils. They observe the filtering ability of soils by... (View More)

In this hands-on activity, students conduct bottle experiments to learn about the conditions that best facilitate the decomposition of organic material in soil. In the lab, they observe changes in the decomposition of vegetable scraps by varying the... (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)

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)

This is a lesson about Saturn. Learners will reflect on what they have learned by drawing everything they picture when they hear the words Saturn and Cassini, and add labels and captions to their drawing. Students look back at their first exercise... (View More)

In this concluding activity, learners will use notes from an earlier lesson to write a nonfiction piece about Saturn or Cassini. These final projects provide a way for children with varying learning styles to consolidate and share their learning.... (View More)

This is a lesson about Saturn's largest moon, Titan. Learners will examine and sort through images of Saturn's varied moons to see characteristics they share and those which set them apart. Students will write a paragraph about Saturn’s moons and... (View More)

This activity provides tips and ideas for helping children do science with a digital camera–and have fun while doing so. For example, cameras can preserve the presence of transient events like clouds, contrails, rain, snow, air pollution and... (View More)
