Part 3: Gravity in Space. Telescopes and the group project• As an exciting new experiment each group will build their telescope• Then each of you will carry out an observing project to assess the likelihood • We Essential Questions- You should be able to answer these questions by the end of the PowerPoint.. What is the purpose of a telescope?. How do refracting telescopes work?. How do reflecting telescopes work?. Optical Telescopes. Ground based and on satellites. Observations are recorded using a camera instead of the human eye most times. . This is so we can separate colors into light and using times to study changes over time.. S. R. Kulkarni.
