What is a Simple Machine?

A simple machine is a mechanical device that changes the direction or magnitude of a force.  In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. 

The 7 simple machines are:
Gears
Inclined Plane
Lever
Pulley
Screw
Wedge
Wheel and Axle

When I Grow Up

When I Grow Up
by Jack Prelutsky

When I grow up, I think that I
may pilot rockets through the sky,
grow orchards full of apple trees,
or find a way to cure disease.
Perhaps I'll run for president,
design a robot, or invent
unique computerized machines
or miniature submarines.


When I grow up, I'd like to be
the captain of a ship at sea,
an architect, a clown or cook,
the writer of a famous book.
I just might be the one to teach
a chimpanzee the art of speech...
but what I'll really be, I'll bet
I've not begun to think of yet.

Bridges Career Research

This is a screenshot from the Bridges career research website.  It is a great resource for researching careers.  You can find out what they do, the average annual salary, education required, and get links for more information.  One of my favorite parts is that you can read an interview with someone who works in that career.  These interviews can tell you the pros and cons of the career. 

Have you found Bridges to be useful?  What features of the website do you like?  Post your thoughts in the comments section.

The Birth of the V-ROD

In class we are watching a video about Harley Davidson's V-Rod motorcycles (pictured above), that shows how the engineers at Harley Davidson used the Design Process to create the V-Rod. 

The VRSC (V-Twin Racing Street Custom) family was introduced in 2001 in a single model called the V-Rod. The V-Rod was developed as Harley-Davidson first "Power Cruiser", designed to compete against Japanese and American muscle bikes. The "V-Rod" made use of the Revolution engine, developed jointly with Porsche that, for the first time in Harley history, incorporates fuel injection, overhead cams, and liquid cooling. The V-Rod is visually distinct from other Harley-Davidson motorcycles. It can be easily identified by the 60-degree V-Twin engine, the radiator and the hydroformed frame members that support the round-topped air cleaner cover. A distinct difference between the V-Rod and all other Harley production motorcycles, is the location of the fuel tank. The fuel tank on the V-Rod is located underneath the seat, placing the driver on top of it, rather than the usual frontal placement, the "tank" in this place is simple dressing, hiding the frame. Loosely based on the VR-1000 superbike, it continues to be a platform around which Harley-Davidson builds drag-racing competition machines. 

Click here to see a video on how Harley Davidson kept their distinct sound in the V-Rod.
Harley Davidson continued to make modifications year after year to the award winning V-Rod.  In 2009, Harley Davidson introduced the V-Rod Muscle, (pictured above) showing that they have continued the 7 step Design Process (listed below) by reviewing their choices.

1. Identify the Problem
2. Collect Relevant Information
3.  Brainstorm Design Options
4.  Evaluate the Design Options
5.  Select the Best Option
6.  Create Model or Implement the Design
7.  Review Choices

What part of the 7 step Design Process do you think is the most important and why?

Google Earth

Who needs a globe in the 21st century?


Pictured below is a screenshot of Walkersville Middle School from Google Earth.  Google Earth uses satellite imagery to map together pictures of the whole planet.  Google Earth is another free Google tool that can be downloaded to your home computer.  Google Earth is located on our school's application menu, under the Internet tab.  Click HERE to see how to get started.  Click HERE to see how to add placemarks.


Are you an advanced Google Earth user?  Try out Google Sky (pictured below).  All you have to do is open Google Earth and click on the planet icon to switch into Sky mode.  Click HERE to see this and other cool features in Google Earth.


Can you find your house using Google Earth? Can you find Orion's belt using Google Sky?  How might this be useful for school, planning a trip, or for sightseeing?
