Matter of the day: Particle Size Scale

Diagram:

Grain Size Pic

'Zandlineaal' - obique view of plastic disc with cells in which sand of different grain size is kept. Meant to be used for estimating grain size of sand. Grain sizes: 16, 50, 75, 105, 150, 210, 300, 420, 600, 1000, 1400, 2000 micrometer

What it is: Rock particle grain sizes range from very fine (clay), fine (sand), medium (sand). coarse (pebbles), up to boulders.

Why it Matters: It allows us to communicate the sizes of small particles.

    Matter of the day:

    Static Cling

    Diagram:

    What it is:

    In a dryer, clothes swap electrons, leaving some with more (- charge) or less (+ charge.)

    Why it Matters:

    Use dryer sheets to balance charges.

    _____________________________________________________________

    Vocabulary:

    Static Electricity: charges build up on an object, but they do not flow continuously.

    electric force is the attraction or repulsion between electric charges

    An electric field is a region around a charged object where the object’s electric force is exerted on other charged objects

    Conservation of charge: an object becomes charged only when electrons are transferred from one location to another. Charges are neither created nor destroyed. If one object gives up electrons, another object gains those electrons.

    There are 3 methods by which charges can be transferred to build up static electricity:

    • Charging by friction is the transfer of electrons from one uncharged object to another by rubbing.
    • Charging by conduction is the transfer of electrons from a charged object to another object by direct contact.
    • Charging by induction is the movement of electrons to one part of an object that is caused by the electric field of a second object.

    static discharge is the loss of static electricity as electric charges transfer from one object to another.

                  Electric Motors
    Add caption

    Diagram:  

    What is it?:  
         .A device that switches the direction of a current in a loop to generate a switching magnetic field. When placed in a magnetic field, the loop can b e forced to spin.
    Why does it matter?.
       . Most types of electric motors work on this design.
    _____________________________________________________________
    Vocabulary:

    An electric current (flowing electrons) produces a magnetic field (area of magnetic force with aligned spinning electrons.) (i.e. wrapped wire connected to a battery can pick attract some metals.)
    An electromagnet is a magnet can be turned on and off using electricity. (motors, loudspeakers, microphones, & switches)

    Hello world!

    I am a 6th-grade science teacher looking to improve student learning through the integration of new web resources.

    This past year, I used the template-driven resources of MySite.com with the activity and data collection resources of Quia.com. I used MySite’s blog utility daily to keep students informed about class activities. I recently integrated worksheet and other resource links.

    This blog will be an attempt to expand on last years work and inform interested parties about my progress in developing uses for easily accessible web resources.

    I have also invested time this summer learning web languages such as XML, CSS, php, AJAX, ASP, MySQL, and .NET. I purchased older software tools such as Dreamweaver/Fireworks/Flash 8 and Corel Graphics Suite 12 on ebay for tens of dollars in order to speed up development and maintenance (a trade-off in size of code.)  I am using older 2.8gHz Dell desktop and Acer 1.6 gHz laptop systems.
