This activity is about crater formation in the solar system. Through a simulation using mud and other materials, learners will observe crater formation and identify the distinctive features of impact sites. A diagram with crater features labeled is... (View More)

This is a lesson about the search for life on Mars. Learners will participate in three activities. In the first activity (Imaginary Martians) learners will compare a fictional organism with what they know about life on Mars today. In the second... (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)

Working in teams of two, learners will observe the characteristics of and classify crustal material samples. They will then infer causes for the characteristics of the different samples and the history of the "mystery" planet they originate from.... (View More)

Learners will use candy bars, straws and other materials to simulate the extraction of a Martian core sample and how to derive observations about the history and make-up of Mars. This is activity 3 of 25 from the collection, Mars Activities.... (View More)

This activity is about the use of remote sensing in planetary exploration. Learners will find out how human curiosity in planetary exploration results in science questions, engineering solutions, and teamwork. This activity demonstrates how... (View More)

Learners will use samples of crustal material to sort, classify, and make observations about an unknown planet. From their observations, students will interpret the geologic history of their mystery planet and make inferences about past life or the... (View More)

Learners will use balloons to construct a scale model of the Earth, Earth's Moon and Mars in relation to each other. They will use this model to predict distances and reflect on how scientists use models to construct explanations through the... (View More)

This is a lesson about observing and examining meteorites in a Meteorite Sample Disc. Learners will practice scientific techniques, develop skills in acquiring data through the senses, observe, examine, record, and sketch data, use magnifying... (View More)

This is a lesson about planet formation. Learners will observe and describe differentiated samples in the Meteorite Sample Disk (or photographs), conduct experiments to model the separation of light and heavy materials within a planetary body,... (View More)
