All Six Simple Machines in One Project!

This project is an example of something we call a "Rube Goldberg Machine".  Rube Goldberg was a famous engineer, inventor and cartoonist.   He was best known for drawing fun cartoons that showed many different simple machines being used to do something very simple at the end.

You can read more about Rube Goldberg here:

Rube Goldberg machines are very challenging to build and require your brain to use a lot of science!  Here is a great example of a Rube Goldberg Machine

And here is Steve Price, who was a contestant on "America's Got Talent" demonstrating his Rube Goldberg Machine:

You can Google "Rube Goldberg Machines" and find examples of hundreds more!  Students all over the world are building them as part of their Science Class.

This scientist makes neat Science Kits, but you don't need to buy a kit to get some great ideas!  He has videos on most of his projects.  Take a look and see if you can find one you can do on your own.

Ducksters - Chemistry for Kids

"Chemistry is the branch of science that studies the properties of matter and how matter interacts with energy. Chemistry is considered a physical science and is closely related to physics. Sometimes chemistry is called the "central science" because it is an important part of other major sciences such as biology, Earth science, and physics. Scientists who specialize in chemistry are called chemists. "
