This week on NASAexplores we're featuring the articles, "Wide Load!", on
NASA's cargo aircraft - Super Guppy, and  "Down-To-Earth Space Exploration,"
on how NASA uses places on Earth to prepare for space environments.  Below
are abstracts of the articles, as well as brief descriptions of the
accompanying lessons for each grade level.

NASAexplores is also pleased to announce the addition of content from NASA's
Office of Biological and Physical Research (OBPR). Every 2 weeks,
NASAexplores users will enjoy articles and lessons on new OBPR topics. In
this week's addition, we're featuring "City-Swallowing Sand Dunes," which
discusses the physics of sand dune movement and how these dunes can threaten
habitation and agriculture.

The Super Guppy isn't a fish. Instead, it's one of NASA's more
unique-looking cargo aircraft.

K-4
Lesson 1 - Pull!  To discover how pulleys work.

Lesson 2 - This Guppy Is A Plane!  To design a product based on its name.

5-8
Lesson 1 - By Land Or By Sea?  To map paths from Los Angeles to Cape
Canaveral by land and by sea, and to calculate the time needed to travel
each path.

Lesson 2 - Acute One Or An Obtuse One?  To determine types of angles and
estimate their measures.

9-12
Lesson 1 - "C" What The Guppy Can Do:  To compare and contrast NASA's Super
Guppy and the Air Force's C-5 and C-130 transport planes.

Lesson 2 - Flying By Angles:  To determine the measures of angles using
geometric postulates.

Topic 2: Down-To-Earth Space Exploration

What do the ocean, the desert, and the Antarctic all have in common? These
future of flight.

K-4
Lesson 1 - Describing The Desert:  To use a KWL chart to learn about the
characteristics of a desert.

Lesson 2 - All About Analogies:  To learn about analogies, and to sharpen
thinking skills by completing word analogies.

5-8
Lesson 1 - Where On Earth?  To learn about Mars geography and compare its
regions to harsh environments that can be found on Earth.

Lesson 2 - Radical Places:  To research extreme places on Earth that are
used to test astronauts and equipment before being sent to space, and to
create a presentation for the class about them.

9-12
Lesson 1 - Geology Of Mars:  To identify landforms on the surface of Mars
and the geological processes that produced them.

Lesson 2 - Is It Mars Or Mars-like?  To compare the analog of Devon Island
to Mars.

Topic 3: Down-To-Earth Space Exploration

NASA-supported researchers are studying the complex physics of migrating
sand dunes--a grave concern in nations where the relentless advance of
desert dunes is a serious threat to habitation and agriculture.

K-4
Lesson 1 - Fine And Sandy:  To analyze sand to learn that different types of
sand are formed in different ways.

Lesson 2 - Sand In The Wind:  To demonstrate how sand can be transported by
wind.

5-8
Lesson 1 - Sand On The Run:  To learn how sand can be transported by wind,
and how wind speed and direction affects its movement.

Lesson 2 - Granular Flow Of Gravel:  To study the granular flow of gravel.

9-12
Lesson 1 - Pour, Pour Sand:  To study the characteristics of sand in
different situations.

Lesson 2 - Like Granular Flow In A Timepiece:  To learn more of the basics
of granular flow and some of the experiments that are being done.
