Subject: NASAexplores This Week!

This week on NASAexplores we're featuring the articles, "Taking It To The
Limits," on the development of spacecraft propulsion, and "Shielding Against
Space Rays," on what NASA is doing to protect astronauts from cosmic rays.
Below are abstracts of the articles, as well as brief descriptions of the
accompanying lessons for each grade level.
To access the articles and lessons, please visit the NASAexplores web site:
<http://www.nasaexplores.com>.
Topic 1: Taking It To The Limits
Air-breathing rockets use air instead of rocket fuel for propulsion. A new
type of rocket uses both technologies, and tests show that it can switch
back and forth between air-breathing and traditionally fueled methods.
K-4
Lesson 1 - From Jet To Portmanteau: To learn how to form and recognize
portmanteau words.
Lesson 2 - Rocket Relay: To use a relay race to simulate a rocket's
transition from one stage to the next.
5-8
Lesson 1 - Hop On A Hybrid: To cooperatively research a vehicle through a
Web quest to determine how it works, how it affects the environment, and how
much it costs to maintain for a year.
Lesson 2 - That's So Cliché: To learn about clichés and choose one to
present in a visual form.
9-12
Lesson 1 - Calculating A Launch: To use stoichiometry to calculate the fuel
and oxidizer requirements for the launch of a rocket.
Lesson 2 - Ram, Scram, And Rocket Plan: To design a launch vehicle to
propel a spacecraft into orbit using ramjet, scramjet, turbojet, and/or
rocket engines.
Topic 2: Shielding Against Space Rays
"Human beings are headed into the cosmos" in the new Vision For Space
Exploration, but first NASA has to figure out how to keep them safe along
the way. A new facility will help scientists fight the effects of space
radiation.
K-4
Lesson 1 - Magnetic Fields: To observe magnetic fields around magnets.
Lesson 2 - Traveling The Solar System: To learn about the planets in the
solar system.
5-8
Lesson 1 - Earth's Magnetic Shield: To observe the shape of iron filings
around a bar magnet, and to deduce the basic shape of Earth's magnetosphere.
Lesson 2 - Origami Sun: To make an origami sun, and to learn more about our
nearest star.
9-12
Lesson 1 - Chromosome Concepts: To organize an International Space Station
(ISS) experiment using a concept map.
Lesson 2 - Ray Shielding: To simulate the radiation shielding on a
spacecraft.
