It can be helpful have a plan in advance for color blind students. We suggest that such participants could contribute in another way, by perhaps researching the astronomical objects included in the activity (see our "Science" section
on the previous page) and reporting back to the class, or they could be paired carefully with verbal students who will be able to patiently explain and describe the activity with them.
As part of the "From Earth to the Universe" (FETTU) project, a NASA-funded tactile and Braille poster series for the visually impaired community was launched in 2009. These posters are accessible to both visually impaired and sighted readers. The materials present celestial objects as they appear through visible-light telescopes and in different spectral regions that are invisible to the naked eye. The posters use a combination of Braille and large-format traditional text, and a variety of tactile textures and symbols are shown to represent different physical features and characteristics of the images.
