In this activity, students will use a simulator of an orbiting X-ray observatory to observe a supernova remnant, the expanding gas from an exploded star. They will take X-ray spectral data, analyze them, and answer questions based on that data. This... (View More)

This is a hands-on lab activity about the composition of salt. Learners will explain the general relationship between an element's Periodic Table Group Number and its tendency to gain or lose electron(s), and explain the difference between molecular... (View More)

These two hands-on labs are about the role of temperature and salinity in governing the density of seawater, a major factor controlling the ocean's vertical movements and layered circulation. In the first activity students work in groups to... (View More)

This is a lesson about the science supporting the design and operation of an ion propulsion engine. Learners will study the concepts of formation and discharge of charged particles, attractive and repulsive forces between charged particles, and the... (View More)

Learners will explore the molecular geometry and mechanics of ice. They will create a model of H2O, investigate its molecular structure and its consistent shape. Faraday's experiment is used as background. Activities include small group miming,... (View More)

This is a lesson about ice worlds in the outer planetary regions and the role they play in understanding the Solar System. Learners will role-play stories connecting science-related literature to ice worlds, view and interpret space-based images of... (View More)

This is a lesson about the field of astrobiology, the study of life in the universe, and ice as a preservative for evidence of life. Learners will consider the relationship between ice and life as they investigate the conditions required for life to... (View More)

This is a lesson where learners are introduced to chemical change and the conservation of matter during different types of chemical changes. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes,... (View More)
