Jewelbox Image and StarGauge
How Old Are the Jewels?
You will need to make a good quality printed copy (color printer needed) of the
Jewelbox Image and StarGauge. The image is available to you in three formats.
Select the format that works best for you. Read our notes below about
printer performance for this image.
- TIFF image (4.1 Mb) - this TIFF file of
the Jewelbox Image and StarGauge will provide the highest quality image
for the exercise. You can download the TIFF image directly
by putting your cursor on the link and holding down
the "shift" key and the "right" mouse button at the same time.
- PDF file (361 Kb) - this version of the
Jewelbox Image and StarGauge can be printed as a PDF file - you must have
Reader setup as
a helper in your browser or running as a standalone program.
- JPEG image (1 Mb) - this version of the
Jewelbox Image and StarGauge can be printed directly from its Web page using
the File/Print... option of your browser. You can also download the JPEG image
directly from its page by putting your cursor on the image and holding down
the "shift" key and the "right" mouse button at the same time. This image
is of lesser quality than the other choices but is still acceptable to
perform the exercise.
For best results, we recommend printing the Jewelbox Image
and StarGauge on an ink-jet printer, using the highest
resolution available and good quality paper designed for
use on an ink-jet printer. Resolutions of 720 dpi should
be acceptable, and available on most ink-jet printers.
Resolutions up to 1440 are preferred if available, since
students will be able to distinguish fine detail more easily.
Color laser printers can also be used, but may not produce
an image of as good quality as a good ink jet printer.
Thermal die-sub printers will also produce excellent quality
prints for use in the Jewelbox activity, and may be available
in copy shops such as Alphagraphics or Kinkos.
