    Now this is a science project that dentists would love!

    POSTED AT 06:44 AM

    Remember how I said that your assignment was going to be something Halloweenee?? Well here it is and man this is pure Halloween, just missing the witches, goblins and ghouls. I thought that since you have all become so proficient with mass and volume and have a pretty good grasp of this density thing... we could move on to the real stuff. Who knows, this information might really help you out this Saturday????
     
    So here it is: Check out this website on candy experiments at http://www.candyexperiments.com/ and try your hand at an experiment or two (especially the sink/float) experiment.
     
    Completion of any of the experiments are not necessary but you should respond to the blog over the weekend (I know, I know... homework over the weekend??, but you can do it tonight if you prefer). After you have checked out the website answer the following questions. That is it!
     
    1) What is your favorite type of candy?
    2) How do you think you could maximize your volume of candy that you acquire on a Halloween night?
    3) How do you think you could maximize your mass of candy that you acquire on a Halloween night?
     
    Good luck!

    Looking back on density and mass...

    POSTED AT 01:54 PM

    Now that you have had some time to look into what mass and density are, lets see what other students thoughts have been.
     
    For this weeks assignment you will be looking at one other students (we will call them your "peer") thoughts on the last three blog postings to assess what they learned about density and mass. You will be assigned a specific student's blogs to read (the list is below) and you should read all three blogs ( first blog "Your thinking on density..." , second blog "Density... Take Two!" third blog "New Planets and their Masses?"). Please respond to the following questions AFTER you have read your peer's blogs.
     
    1) What do you think your peer has learned about mass?
    2) What do you think your peer has learned about density?
    3) What is one thing that you found interesting about your peer's blogs?
    4) What would be one question you would like to ask your peer concerning his/her blogs?
     
    Good luck with this, and please take your time and be conscious of other peoples feelings when responding.
     
    Thank you for being a great class!

    New Planets and their Masses?

    POSTED AT 12:45 PM

    So we have started to really get into this density stuff and we know that density is not really something that can be directly measured... right? For instance, you can not just go up to somebody's car, poke it in the door with your "dense-o-meter" and figure out the density of the entire car. What you have to do is first find out the object's mass and then the object's volume. When you compare the object's mass to it's volume, you are looking at density! For example, if you have a really heavy object that takes up a little bit of space, you would say it is dense. If you have a really light object that takes up a little bit of space, you would say it is less dense.

    But what if you have a Planet? Check out this link on a recently published article on the discovery of 32 new planets (not in OUR solar system). http://news.nationalgeographic.com/news/2009/10/091019-32-new-planets-found.html
     
    Now that you have had some time to read the article about the new planets answer the following questions:
     
    1) Why are scientists excited to find "low-mass" planets?
    2) I thought mass had to be measured! How do you think these scientists are discovering the "mass" of a planet they have never visited?
    3) Even if they did visit the planet... how do you think they can calculate the mass of an entire planet... is there a scale that is big enough?
     
    Tough questions indeed, but I think you all can do an amazing job! Just get your head out of the clouds and into the stars!

    Density... Take Two!

    POSTED AT 08:12 AM

    Alright folks... we are now on to our second installment of density and this time we are going to discuss diamonds. Follow these steps carefully... many of you had problems with the last posting.
     
    1. First check out this website from Cornell University on diamonds http://www.ccmr.cornell.edu/education/ask/index.html?quid=724
    2. Now that you have read the article, answer the following question to the best of your ability: "What do you think is another way someone could tell the difference between a real diamond and a fake? Please explain your answer in detail!"
    3. Post your response for Thursday 10/15/2009
    4. Finally check out the responses from the previous blog and, if you would like, post a response to one of your classmates ideas.
    That is it!

    Your thinking on density...

    POSTED AT 06:29 AM

    Your homework is to do two things...
     
    1) Check out this website and read the section on "DENSITY" (You do not have to read about buoyancy, but you are more than welcome to do so. Here is the link  http://www.visionlearning.com/library/module_viewer.php?mid=37
     
    2) After reading the article you should answer the following question to the best of your ability.
                
                "Based upon your reading; what do you know about density? What did you find the most interesting about density?"
     
    This is due on Wednesday 10/7/09
     
    See you soon!
