1. Science as it is taught in the classroom can be quite boring and often prohibitive for children who are more kinetic learners. Get your kids involved with an inexpensive, but still powerful, telescope designed for aspiring astronomers.
2. Nearly all children are enchanted with the cosmos, but so few get a chance to peer into it. These days, modern technology and production techniques mean more children than ever will be able to view and profoundly understand the orbits of the planets, the space between stars, even the striking but oft-overlooked details of our own Moon.
3. Both reflector and refractor telescopes can be built with a child in mind, but due to the nature of the design, refractor telescopes might be a better choice. The precise lens grinding and firm position seen in a refractor telescope means you won't need to perform as much maintenance as you would for a reflector telescope.
4. There are a number of very inexpensive telescopes geared for use by children, but often these are simply too bare bones to be of any use. Remember, optical products require very precise lens grinding or mirror shaping. No telescope should be so inexpensive that you feel you can purchase impulsively.
5. Brands that make astronomical products especially for kids include Tasco, Bushnell, Celestron, Vixen, and Meade. With these and the many others available, you'll easily find the kids telescope that you're looking for.
