On the Moon Educator Guide

Audience: Educators
Grades: 3-12 and Informal
Product Number: EG-2009-02-05-MSFC



NASA is one of the largest employers of engineers in the world. "Design Squad®," an award-winning TV show that airs on PBS, engages teams of students in imaginative engineering challenges. Together, NASA and "Design Squad" have developed the On the Moon Educator Guide. The guide brings hands-on engineering and the adventure of space exploration to life for students. The activities are related to NASA's Lunar Reconnaissance Orbiter and NASA's Lunar Crater Observation and Sensing Satellite missions. In this guide, students are challenged to design and build:
  • An air-powered rocket.
  • A shock-absorbing system that will protect two marshmallow "astronauts."
  • A rubber band-powered rover.
  • A cardboard crane for maximum load-lifting ability.
  • A paper cup modified so that it can carry a marble down a zip line and drop a marble onto a target.
  • A solar hot water heater to cause the greatest rise in temperature.

Online Training for Teaching Hands-On Engineering Activities with NASA and "DESIGN SQUAD®"

NASA and "DESIGN SQUAD®" have developed an online workshop for educators and afterschool leaders to build their skills and confidence in guiding kids through engineering activities like those from the On The Moon Educator Guide.

Completing this self-guided online workshop will allow educators to gain insight and strategies for strengthening critical-thinking skills and exciting their students about using the design process to arrive at solutions.

Belajar Kepada Para Peraih Nobel

The Nobel Foundation was founded as a private organisation on 29 June 1900. Its function is to manage the finances and administration of the Nobel Prizes.

In accordance with Nobel's will, the primary task of the Foundation is to manage the fortune Nobel left. Robert and Ludwig Nobel were involved in the oil business in Azerbaijan and, according to Swedish historian E. Bargengren, who accessed the Nobel family archives, it was this "decision to allow withdrawal of Alfred's money from Baku that became the decisive factor that enabled the Nobel Prizes to be established".

Another important task of the Nobel Foundation is to market the prizes internationally and to oversee informal administration related to the prizes. The Foundation is not involved in the process of selecting the Nobel laureates.
Perkembangan Ilmu Pengetahuan dan Teknologi bisa dipercepat di kalangan masyarakat Indonesia dengan berbagai cara, salah satu diantaranya adalah penghargaan yang layak bagi para peneliti kita.

Semoga

Salam dari Arip Nurahman.

Laboratorium Astrofisika

Laboratory and Astronomical Observations of the CN Radical at Millimeter Wavelengths
 
Instructor: Carl Gottlieb
 
The project will entail observation of the fundamental rotational transition of the CN radical at 113 GHz in a low pressure glow discharge with a sensitive laboratory millimeter-wave spectrometer located in the School of Engineering and Applied Sciences (Pierce Hall, 29 Oxford St.) and toward the Orion nebula with the 1.2 meter millimeter-wave telescope on the roof of building D at the CfA. Accurate rest frequencies, required for the astronomical phase of the project, will be measured in the laboratory. The abundance and radial velocity derived from the astronomical spectrum of CN will be compared with those of other molecules in the Orion molecular cloud. The project provides a good introduction to the physics and chemistry of gas discharges, liquid helium cooled detectors, vacuum and gas handling techniques, computer controlled data acquisition, millimeter-wave astronomy, and the physics and chemistry of interstellar molecular clouds.

Laboratory Astrophysics
Science is successful because the physical laws we discover on Earth work everywhere and every when. We use laboratory experiments to expand our understanding of physical processes and then apply these results to the processes throughout the Universe. In some cases laboratory experiments can reproduce similar physics. For example, highly charged plasmas can be created in the laboratory to study the collisions between electrons and ions that occur in the hot solar corona. In other cases, such as in the extreme environments of black holes, we cannot reproduce the conditions. However, even in those cases, the pattern of observed spectral signatures allows us to identify the species and determine some of the physical conditions and processes. Spectral features observed in the solar corona are also observed from black hole sources.
