Skill Sheet 27.1: Arthur Walker
1. You may wish to have students compare and contrast their
definitions with those of a student who used a different
source. Discuss with the class the value of using a variety of
sources and the importance of crediting these sources.
2. Walker didn’t allow prejudice to dissuade him from pursuit of
his goals. As a result he made important contributions to
science and society. He also spent time and energy helping
other members of minority groups achieve their own goals.
3. A spectrometer separates light into spectral lines. Each
element has its own unique pattern of lines, so scientists use
the patterns to identify the ions in the corona. Temperature
can be determined by the colors seen in the corona. For
example, red indicates cooler areas, while bluish light
indicates a very hot area.
4. Magazines and journals that may have one of Walker’s
photographs can be found at public and university libraries.
You might suggest that students contact a reference librarian
for assistance.
5. The committee found that the accident was caused by a
failure in a seal of the right solid rocket booster. They also
made nine specific recommendations of changes to be made

2. Outstanding students from around the world are nominated for
the prestigious Rhodes scholarship. Rhodes Scholars are invited
to study at the University of Oxford in England. Only about 90
students are selected each year. This scholarship is awarded by
the Rhodes Trust, a foundation set up by Cecil Rhodes in 1902.
3. A larger telescope allows more light to be collected by the
mirrors and/or lenses of the telescope. More light allows for a
clearer image, which can then be magnified to show greater
detail.
