This week we’ll learn all of this fun little poem:

Snowball

By Shel Silverstein

I made myself a snowball

As perfect as could be.

I thought I’d keep it as a pet

And let it sleep with me.

I made it some pajamas

And a pillow for its head.

Then last night it ran away,

But first it wet the bed.

Finally, our next book club book is Clementine by Sara Pennypacker. We’ll discuss this next week!

What comes to mind when you think of a machine? The washer? A tractor? A complex candy wrapping machine in a factory? All of those are machines, but machines have been around thousands of years longer than any of those inventions. On the most basic level, there are six simple machines. And while they’re simple, they’re mighty! In fact, they helped build the Great Wall of China, the Pyramids, and many more things.

To better understand simple machines, read How to Lift a Lion by Robert Wells.

Also, watch this video from The Good and the Beautiful on simple machines. In particular, pay attention to why we need simple machines and how often we still use them today!

All simple machines make work easier because they give the user mechanical advantage. Scientists define mechanical advantage as a measurement of how much a machine multiplies the force you input.

Watch this video to see how much mechanical advantage a simple pulley system gives one teacher over the other.

Now it’s time to have some fun with everything you’ve learned about simple machines. Pick at least one of the activities below to play with simple machines.

Can you find three ways to lift a lion?

Launching Snowmen with a lever (this one would be especially fun if we get some snow! The project suggests ping-pong balls for the snowmen, but any small balls, wads of paper, or balled up socks could also work)

Investigating Levers (best for younger Rookies)

Build a Simple Pulley

How did your project go? Was it fun? What did you learn about your simple machine? Can you think of anything you could change to make your simple machine work better? Discuss these with your dad or older siblings over dinner one night this week.

Lastly, enjoy listening to this story about the very first Ferris Wheel! Did you know a Ferris Wheel is just a large wheel and axel powered by some sort of motor?
