    Summer Homework August 12th Meteor Shower

    Meteor Shower!

    August 12th (peak) - The Perseids (pronounced /ˈpɝsiːɨdz/ pûr'sē-ĭdz) are a prolific meteor shower[1] associated with the comet Swift-Tuttle. The Perseids are so called because the point they appear to come from, called the radiant, lies in the constellation Perseus. Meteor showers occur when Earth moves through a meteor stream. The stream in this case is called the Perseid cloud and it stretches along the orbit of the Comet Swift-Tuttle.

     8th grade Science


    "Science is a way of thinking much more than it is a body of   knowledge."

    Carl Sagan

    Food for thought:

    "Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out."

    Stephen Hawking

    Dear Parents and Students- 

    Please note the section called "Class Files".  The “Class Rules and Expectations” along with “How to Write A Science Lab” are updated copies that you (student) received at the beginning of the year.  You should find them in your Science notebook/"handout" section.  

    Also, students, if you need any extra copies of some of the lab forms (“Table” and “Graph” worksheet forms), you may print these out for your use. 

    Lastly, for your reference, whether you want to check up on Tornado or Hurricane Scales, to find out whether the North American tectonic plate really does stretch around and includes part of northern Japan, or keeping up-to-date in astronomy, technology, marine biology, or any of the other sciences check out some of the website links below.  Go to Mars, zoom in on Olympus Mons, get updates about the rovers, Spirit and Opportunity,……… or, maybe you want to take a virtual submarine tour of the Gulf Reefs!
