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)

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)

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)

Keywords: Reaction times
Audience: High school
Materials Cost: Free per student

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)

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)

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)

Keywords: Aviation hazards

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)

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)
