# Nasa Wavelength

## Site Seeing: Beginning

In this fieldwork activity, students learn that when setting up a research design a system's boundaries are based on the question(s) a scientist wants to answer.

## The Fall of the Ruler

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 required to accomplish a specific task.

## Exploring Relationships Among Variables Six Months Apart

In this activity, student teams explore connections between parts of the Earth system, by examining a time series of environmental data maps.

## MY NASA DATA: Radiation Comparison Before and After 9-11

Air traffic (and therefore airplane contrails) was halted nationwide for nearly three days following September 11, 2001. Students will investigate whether that stoppage resulted in any changes to cloud cover, temperature and/or radiation.

## Kepler Mission Fact Sheet

This 2-page color fact sheet briefly describes NASA's Kepler mission, its instruments, and ground system. Also included are tables listing the instrument parameters and the major institutions involved.

## Magnetic Earth and the Lithosphere

In this problem set, learners will use a map of satellite data on Earth's surface magnetism and determine coordinates and distances for variations in magnetism. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change.

## NASA eClips™: Launchpad: ICESat-2 - Next Generation Technology

Learn how the second generation of the Ice, Cloud, and Land Elevation Satellite, better known as ICESat-2, is being used to map the ice structures in the world's polar regions.

## Moon Pie

Learners will work in teams to apply their knowledge about the Moon, its environment, and the LRO mission to match responses to Moon questions. With the correct responses, they build a picture of the Moon. This activity is part of Explore! To the Moon and Beyond!

## What are Satellite Images?

This is an activity about image analysis. Learners will create a map of the room and discuss the perspectives shown in their drawings and how this relates to satelite images.

## Multiwavelength Astronomy: The History of X-Ray Astronomy

This story-based lesson presents information on the early investigation into solar and cosmic X-rays, as well as the scientists working in pursuit of X-ray detection and imaging, that set the stage for a program of space-based astronomy. The lesson is narrated by Dr.
