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)

Learners will compare and contrast images of Earth and Mars and then experiment with lenses to understand more about the instruments used to make the pictures. This is activity 1 of 9 in Mars and Earth: Science Learning Activities for After School.

In this activity, students experiment to test the hypothesis that Mars was once hotter. The activity requires some advance preparation by the teacher: the day before the activity, need to place a plastic bottle filled with water in the freezer.... (View More)

This is a lesson about designing and building an effective sunshade for a model MESSENGER craft. Learners will build a model of MESSENGER. They will use a scientific approach to solve problems and work as a cooperative team. They will discover their... (View More)

This is a activity about applying the scientific method to a design challenge. Learners will design and build a platform that will be placed on a heat source. The platform is expected to serve as an insulator for a cube of gelatin. The goal is to... (View More)

This is a lesson about the Cassini mission to Saturn. Learners will create their Saturn Discovery Logs. They will use the Saturn Discovery Log to chronicle their journey of discovery about Saturn and Cassini through nonfiction writing. For their... (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 the Cassini Spacecraft. Learners will engage in basic problem-solving as they design and construct their own small model of a spacecraft. Through writing and illustration, students will document their work and will complete a... (View More)
