Using the six simple machines, design a contraption to pop a balloon.

- Your contraption must use all six simple machines twice.

- You must be creative.

- You must detail each of the steps involved in your contraption (i.e. “Step 1: A rock is rolled down a ramp…”)

- You must include calculations for velocity, acceleration, force, pressure, work and power in your contraption’s description.

This thought experiment is worth a total of 10 points.

Should be fun!

As you know, many of what are considered the greatest buildings in history (the Pyramids, the Colosseum, even the Washington Monument and the Capitol in Washington, D.C.) were built without the help of the massive machines we so often see around construction sites today.

Instead, these buildings were constructed using human sweat, power and ingenuity…and simple machines.

One example of an incredible building project that seemingly defies logic is the Parthenon. We’ll be studying how the Parthenon was constructed using simple physics and easy-to-construct machines and has stood the test of time.

Head over to PBS’ Nova site and learn more about the Parthenon if you’re interested (it’s worth your time!):

NOVA: Secrets of the Parthenon

I’ll try to dig out the pictures I took of the Parthenon and Acropolis when I visited the site while in college!
