This is a series of three webpages about how humans and computers communicate. Learners will explore the binary and hexidecimal systems and how engineers use them to translate spacecraft data into images.
This is a game about data compression. Learners will use virtual foam balls to explore the different compression methods (lossless, lossy, and superchannel) used by the Earth Observing 3 mission.
This is a lesson about spacecraft communication. Learners will explore the concepts of "signal" and "noise" by listening to a computer-generated signal from two different distances with no additional background noise, and then with background noise,... (View More) and compare their experiences in a science journal page. (View Less)
Learners will investigate, discuss, and determine why humans have always explored the world (and now space) around them. Students determine these reasons for exploration through a class discussion. In the first activity, students use the Internet to... (View More) examine the characteristics of past explorers and why they conducted their exploration. The students then examine why current explorers - including the students themselves - want to explore other worlds in the Solar System. By the end of the lesson, the students can conclude that no matter what or when we explore - past, present, or future - the reasons for exploration are the same; the motivation for exploration is universal.

This is a lesson about how to plan a mission to explore another world in the Solar System. Learners will discuss the path of a spacecraft traveling between planets, examining the journey from the Earth to Mars as an example. In Activity 1, students... (View More) determine the pros and cons for different ways we can explore another world, either by observing from the Earth or by sending a spacecraft to fly by, orbit, or land on the world. In Activity 2, the students plan a complete mission to explore another world in the Solar System. By the end of the lesson, the students come to understand that what scientists want to learn about an object determines how they plan the mission, but real-life constraints such as cost and time determine what actually can be accomplished.

In this problem set, learners will become familiar with two measures of electricity: watts and kilowatt-Hours. They will calculate the electrical consumption of several household items, such as appliances, as well as its cost. Answer key is... (View More) provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change. (View Less)
In this lesson, learners will discover how certain snakes (pit-vipers) can find prey using a natural infrared sensor and will extend their understandings by exploring infrared technology applications. The lesson features background information for... (View More) the teacher, pre-requisite skills and knowledge for the student, a mini-exploration of infrared image technology, multiple image sets, assessment information, student worksheets, extension and transfer activities, and additional resources. This is lesson 2 on the Infrared Zoo website. (View Less)
This interactive adventure engages children in a story-based scenario that emphasizes concepts of remote sensing and how NASA scientists use satellite imagery to better understand the Earth's environmental changes. The story features a pigeon named... (View More) Amelia and is set in New York City. Amelia's owner, a young girl named Maria, receives a gift from her grandfather-a camera specially designed for strapping on to a pigeon along with copies of old photographs taken of New York City landmarks. Suddenly, Amelia's flights around the city take on new relevance; she visits the Bronx Zoo, Central Park and Battery Park to take updated pictures of those same landmarks from her "birds-eye" perspective. Through Amelia's adventures, and with some help from a NASA scientist, Maria learns about the history of aerial images, the use of images to detect changes over time, the significance of color, texture and shape in interpreting those images, and the importance of images taken from today's NASA satellites to our understanding of Earth. The story is set in New York City, chosen for its size, diversity and the visibility of prominent features in satellite imagery. (View Less)
This activity has two purposes: challenge the learner to develop a procedure for investigating a research question and to learn more about factors affecting the dynamics of air in motion. It demonstrates that warm air and cold air differ in weight... (View More) and this difference affects air's vertical movement in the atmospheric column. Resources provided to students for this challenge include a homemade balance beam made of wood, two paper bags, a desk lamp, paper clips, tape and a thermometer. The resource includes background information, teaching tips and questions to guide student discussion. This is the chapter 8 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.
