This Moveable Museum article, available as a nine-page printable PDF file, offers a thorough, kid-friendly look at telescopes. It discusses the following four concepts in depth, and provides a reading list for further research:
- telescopes collect and detect light, like giant eyes
- telescopes' advantages over eyes include a larger light-collecting area, collecting light for longer periods of time, and the ability to detect wavelengths of light invisible to humans
- different telescopes collect different wavelengths of light
- telescopes in space avoid interference from the Earth's atmosphere
