Comments made by teachers who use AstroCappella in their curricula:
"Fun."
"Engaging."
"A wonderful way to communicate complex science concepts and vocabulary."
"The students love it and I don't have to stand on my head to keep their attention."

Dear Chromatics,
I'm the editor of Science@NASA (http://science.nasa.gov) and the author of spaceweather.com, and I'm writing to say thank you for "Noctilucent Cloud." I've just finished listening to it six times in a row, and I enjoyed it more each time I heard it. What a gift you have for science communication!

"The music of AstroCappella serves as a great hook to gain the attention of students and, perhaps, even to invade their minds with choruses of science. The activities included can then follow up on the concepts imbedded in the songs. At a recent workshop in Palm Springs, CA, one teacher came up to me to say that she had been teaching the electromagnetic spectrum to her class. Their response was 'less than enthusiastic'. This teacher had heard the Chromatics perform some of the AstroCappella songs several years ago and thought the music might help engage her students. She played "Cosmic Radio Show" for the class and had them try the activity to create a radio antenna out of an umbrella. She was thrilled at the response of the students and reported that for days afterward she heard 'Hey, ho, did you know there's a Universe in the radio?' coming out of her students."

I wanted to let you know how much my kids have been hooked on your wonderful sound these past two days...the 10 year old, Adam, has memorized four of the songs already!

This is such a lovely song! The Chromatics are just amazing in their abilities to make the science so poetic and the music so beautiful...

I can not thank you enough for your creative, scientific and humorous approach to astronomy. I am a new 7th grade science teacher. I used your "Sun" song today and will use "Doppler Shifting" tomorrow. The kids LOVED it and remembered so much just from your song. You are doing a lot of good for the future science community by helping us teachers to make science fun! Keep up the good work.
