Measuring Outer Space
Make a telescope, Make a star clock
Astronomers determine the size and distances of stars and planets without ever leaving the earth. How can you measure a size or a distance remotely? How are sizes and distances measured in outer space? 
Can a telescope be of help?


Material and instructions:
In this project you will get familiar with tools and techniques of astronomy. You will learn how to build a simple telescope. You will also learn how to tell the time at night by the position of stars. You will finally learn how to measure the size and distance of objects from far distances. Do a visual exploration of sky. Record your discoveries and exchange information with others about what you have discovered.
