TELESCOPE



A telescope is an instrument that makes a far away object look closer. To do this, a telescope has a device that collects light from a distant object (objective lens or primary mirror) and brings that light (image) to a focus where a second device (eyepiece lens) magnifies the image and brings it to your eye. To make a simple telescope at home, you will need the following:
*Two Magnifying glasses – perhaps 1 – 1.5 inches (2.5-3 cm) diameter (it works best if one is larger than the other)
* A Cardboard Tube- paper towel roll or gift-wrapping paper roll (it helps if it is long)
* Duct Tape
* Scissors
* A Ruler, yard stick, or tape measure
* Sheet of printed paper- newspaper or magazine will do.
