This short video (~2 minutes) explains how a raindrop falls through the atmosphere and why a more accurate look at raindrops can improve estimates of global precipitation. This information is important to scientists working on the Global... (View More)

This collection of activities is based on a weekly series of space science mathematics problems distributed during the 2012-2013 school year. They were intended for students looking for additional challenges in the math and physical science... (View More)

In this activity, participants learn about the hydrosphere by making observations and taking measurements. They will go outside and use scientific equipment to investigate temperature, pH and transparency of a body of water. They will use this... (View More)

This is a demonstration about the density of the planets. Learners will compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods. They will then dunk the "planets" in water to highlight the fact... (View More)

This is a lesson about crystal growth. Leaners will grow a sugar crystal and learn how this relates to growing protein crystals in space. The lack of gravity allows scientists on the space station to grow big, almost perfect crystals, which are used... (View More)

In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

In this textbook chapter, students review concepts of matter and energy as a precursor to understand how carbon dioxide traps heat in the atmosphere. This is the second chapter in the unit, Climate Change, which addresses the question of how human... (View More)

Students will learn about black holes through reading a NASA press release and viewing a NASA eClips video segment. Then students will use tables and mathematical expressions to compare black hole sizes and temperatures. Common Core State Standards... (View More)

In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star, as they learned in the "Elements and You" activity. They are introduced to the life cycle of a star and to... (View More)

In this lesson, students explore a discrepant event when they design an experiment to measure the rate that ice melts when in pure water versus salt water. It is designed to help students realize that a carefully-designed experiment may yield... (View More)
