Simple Machines : Screws

We are reading and doing the activities from this book that came with the Simple Machines Discovery Kit from our library.  We’ve used another book of the same series before, and we really liked it.

This one is fun too.  It divides the studies in the simple machines, and we are reading chapter by chapter and doing the projects that look more fun.

When we got to the chapter in screws I thought I’d skip it, thinking I wasn’t sure I wanted to read 5-6 pages about screws and its history.  But the pages make it look pretty simple and with fun facts so I decided to go ahead and read a little.  And I am so glad we did.

It mentioned this American artist, Andrew Myers who does portraits using screws.

We read also that the largest drill bit (a type of screw) in the world was the one used to make the largest and deepest tunnel in the world that will cross the Swiss Alps.  Look at this Tunnel Boring Machine.  It is three stories long.

Then of course we had to read and learn more about the tunnel.  The Gotthard Base Tunnel a train tunnel that will cross the Swiss Alps, to help congestion in the cities, because of its massive traffic issues, mostly due to trucks going through the country, which is in the middle of Europe, needing to go from one side to the next.  The project was passed in votes in Switzerland in 1992 and the construction began in 1996.  That is 20 years ago.

Of course we found a youtube video (there’s videos online for everything , right?  I love that.)  We first watched this one, of the breakthrough of the tunnel with the giant drill bit working.

But then we watched this one was the most entertaining and informative and I think made our travel juices flowing.

We really liked learning more about it and of course, there’s a great field trip idea for next year.  Wouldn’t it be a great idea to see that tunnel in person?  Not sure I’d like to ride it though… for someone claustrophobic like me, that’s more like a nightmare, but I’d go see it and be there for the news for the opening day.  Hmmm… now I just need to figure out how to make that field trip work into our budget.  Ha!
