Hello teachers, scientists, in my more than 25+ years of involvement in EPO/informal outreach in astronomy, space sciences, one of the toughest parts of this engagement has been how to approach, or work with I should say with those students who are less fortunate. Its a challenge that now can be successfully achieved to help students better understand the world on which we live, and the Universe around us.
During this 25+ years, I've probably worked with more than 100,000 students, the general public, boy & girl scouts, etc. I've since lost track of the numbers, but I know they're way up there! I've attached two (photos) here. One, showing a young lady, who has muscular dystrophy, getting ready to peer through the eyepiece of a telescope, the other picture, is of Noreen Grice's "Touch the Sun", a NASA braille book on the Sun.
Rather your in a wheelchair, or cannot see, doesn't exclude you from learning, it challenges you! For those of you who may have, or know students who are sight impaired, the book is an excellent reference tool on the study of the Sun, and challenges students to put their "sense" of touch to work for them, to feel what "size" is all about! I often fielded questions about the Sun's size, or how many Earths could fit inside it, or across its equator, etc.
I've known many students over the years, two examples, one Noah, who is now on a United States Navy submarine, and Pammy, who just this past year did an internship at the United Nations in New York City. Pammy in fact is a graduate from UC-Berkeley. While they were both students in middle and high school, they were always "involved" in our astronomy activities, often helping others. Their success, can be your "success" as well, so aim for the stars, and go for it!
