This resource is designed to enable presenters (scientists, engineers, etc.) to easily present to an elementary and/or middle school audience and feel confident that the information they are presenting is developmentally appropriate and supports the... (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)

This model demonstrates convection currents and uses water, food coloring, a cup of very hot water and a votive candle as heat sources. Movie clips of demonstration setup and convection in action are provided. This activity is supported by a... (View More)

This chapter provides a series of investigations, ranging from teacher-centered to open inquiry, that involve the formation of clouds in a model cyclone, and demonstrating how the availability of heat (indicated by temperature) affects formation and... (View More)

In this demonstration, sheet cakes are used to show how tectonic forces create convergent, divergent and transform plate boundaries. The resource is part of the teacher's guide accompanying the video, NASA SCI Files: The Case of the Shaky Quake.... (View More)

Wave movement is explored using a metal tray of prepared gelatin, dominoes, sugar cubes, plastic wrap and a rubber mallet, in a demonstration of physical principles supporting the study of earthquakes. The resource is part of the teacher's guide... (View More)

In this demonstration, students learn about the physical process of liquification and how it causes the ground to become unstable during an earthquake. Required materials include a plastic tub, sand, water, a brick and a rubber mallet. The resource... (View More)

Students become familiar with strike-slip faults, normal faults, reverse faults and visualize these geological structures using cardboard or a plank of wood, a stack of books, protractor, and a spring scale. The resource is part of the teacher's... (View More)

In this demonstration, liquids of different density are mixed to demonstrate how the layers of the Earth were formed as the denser materials sank to the inner portion of the Earth with the less dense materials, such as our crust, remaining on top. A... (View More)

This demonstration allows students to visualize how heat moves through convection - using water, food coloring, a small cup and a large jar - and prompts them to make a connection between the observed process and cloud formation. The resource is... (View More)
