Hand in your neutrino summaries soon, please.

Today, you need  to explain the proton-proton chain using some sort of a poem, fairy tale, or musical rhyme, or performance.  Basically, I am asking you to create a way to make the ideas of fusion, energy, neutrinos, the sun, energy, and matter and antimatter understandable to the average 7th grader.  Slides 10-25 of the powerpoint, as well as the web, can help you out.   Digitize your end product and send it my way.


=============During the second half of class===================

Secondly, we are moving on to Telescope Types.  There are tons of different telescopes out there, and all of them have different stated purposes.   Our goal is to summarize each one of the different eras shown below in blue in about 2-6 sentences.  Luckily for us, one website talks about all the types of telescopes.  You may not get done with all the exploration, but you should be at least 1/2 done by Tuesday.

Find out an example ans a 2 sentence summary for each of the following types of telecopes.   The link below is your priamry reources.

Era stories:

Story 1
Galileo's Refractor: Galileo's telescope revealed the first hint of the depths of space. His dedication and approach to explaining what he saw revolutionized astronomy. (Includes one telescope story, one biography.)

Early Refractors: Telescopes with flatter lenses brought wider and clearer views of the sky but required longer tubes. Some refractors were so long that they became difficult to maneuver. (Includes two telescope stories.)


Great Refractors: New technology allowed astronomers to create larger lenses that produced bright, clear images. For a while, refracting telescopes became more popular than reflecting telescopes. (Includes three telescope stories, one biography.)

Story 2
Newton's Telescope: Sir Isaac Newton replaced the main lens of a telescope with a mirror, creating the reflecting telescope. (Includes one telescope story.)


Early Reflectors: Early reflecting telescopes used metal mirrors to look deep into space, but the new design presented new challenges. (Includes four telescope stories, one biography.)


Hugh Reflectors: Astronomers crafted telescope mirrors from glass instead of metal, making reflecting telescopes more powerful and easier to use. They began relying on photography and instruments to record observations. (Includes three telescope stories, two biographies.)


Story 3
Solar Telescopes: Solar telescopes are reflecting telescopes that use special instruments to observe the Sun. (Includes one telescope story, one biography.)


Radio Telescopes: The discovery of radio waves from space launched a new branch of study: radio astronomy. This spurred astronomers to develop new techniques to accommodate the large size of radio waves. (Includes two telescope stories.)


Multi-mirror Telescopes: Multi-mirror telescopes used computer technology to overcome the size limits of huge reflecting telescopes. (Includes two telescope stories, one biography.)


Space Telescopes: By placing telescopes in orbit above Earth, astronomers were finally free to view the universe in all wavelengths of light. (Includes five telescope stories, two biographies.)
