Students create a set of flash cards to assist them in learning the structure of the Earth, including the Earth's crust, inner core, outer core, and mantle. The resource includes a template with cut away diagrams of the Earth's interior. It is part... (View More) of the teacher's guide accompanying the video, NASA SCI Files: The Case of the Shaky Quake. Lesson objectives supported by the video, additional resources, teaching tips and an answer sheet are included in the teacher's guide. (View Less)

This classroom demonstration employs a jar, milk and a flashlight as a model system to demonstrate that light maintains its direction of motion until it interacts with an object or substance, and how atmospheric aerosols scatter light. The resource... (View More) is part of the teacher's guide accompanying the video, NASA Why Files: The Case of the Mysterious Red Light.

This story can be used to teach that results must be checked against known facts to see if they're reasonable. It is designed as a follow up to "The Fall of the Ruler." This resource is from PUMAS - Practical Uses of Math and Science - a collection... (View More) of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications. (View Less)

This activity shows how an ordinary ruler can measure human reaction time (RT). Learners will convert a standard ruler into a time ruler (relating time and distance) and measure each others RT. They will also calculate means and variances and the RT... (View More) required to accomplish a specific task. Additional resources and an extension to this activity are available.

This article explores how statistics can be interpreted in different ways to yield different conclusions. It describes the outcome and discussion of two class activities. In the first, the results are interpreted to "show" that taking a group rather... (View More) than an individual perspective is ultimately beneficial to the individual. In the second, a variation is added "showing" that telling the truth is better that lying.

This example explains how contour mapping teaches both estimation and spatial visualization skills. To have experience visualizing 3-dimensional fields from a 2-dimensional map helps students throughout their mathematical career. This resource is...

Logarithms are very handy when dealing with numbers at different scales but they are also useful helping us average measurements of physical phenomena that have nonlinear behavior. In this example, students learn about cloud albedo and calculating... (View More) cloud optical depth.

Atmospheric scientists use computer models to forecast the position of a moving volcanic cloud, and remote sensing can identify its components, including gases and aerosols. This resource provides ideas for classroom investigation of these topics,... (View More) and directions for a demonstration of light scattering by aerosols. The lesson ideas are from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This example shows how Newton's laws of motion apply to aircraft carriers and introduces the lift equation: the amount of lift depends on the air density, the wind velocity, and the surface area of the wings. The problems stress the importance of... (View More) units of measure.

Students investigate whether global climate change will intensify the effects of hurricanes on coastal communities by determining the areas most vulnerable to hurricane surges by using topographic maps, a physical model, and a time series of... (View More) hurricane data. Students then take on the roles of homeowners in a community and explore whether their home's position with respect to the topography and coast is protected from storm surge and high tide. A coastline map and student activity sheets are included. The resource is supported by teacher background information, assessments, and a scoring rubric. This is a module in the lesson series, Potential Consequences and Climate Variability and Change. (View Less)
