Are you tired of working? Don’t you wish
there was an easier way to get things done? Wait!
There is! We can use simple machines to make work easier. That’s
right. Simple machines make work easier!
How? Well, today that’s what you are going to discover. If you’re tired of working too hard, take the simple route with simple machines. Let’s go ahead and get started. Climb aboard the bus
and get ready for our virtual field trip.
Our first stop: The Basics of Simple Machines.
can’t explore the different simple machines if we don’t even know what a simple machine is. So…take a look at this site http://sln.fi.edu/qa97/spotlight3/spotlight3.html and discover just what a simple machine is.
Stop reading when you get to the part about inclined planes – we’ll get to them in a minute.
I’m glad we know what a simple
machine is and ways that we can use them to help us do work.
Let’s keep rolling….next
stop: The 6 Simple Machines (plus gears). Check out this really cool site to learn
about all six simple machines http://www.smartown.com/sp2000/machines2000/main.htm . Keep clicking the “next” button
to learn about levers, gears, inclined planes, wheel and axles, and pulleys.
Find out about screws by visiting
http://www.usoe.k12.ut.us/curr/science/sciber00/8th/machines/sciber/machine4.htm , and check out wedges at http://www.usoe.k12.ut.us/curr/science/sciber00/8th/machines/sciber/machine3.htm .
If you need more information on any of these topics, make sure you visit http://www.sciencetech.technomuses.ca/english/schoolzone/Info_Simple_Machines.cfm#screw . You may want to use this site as
a reference for some of the activities you’re about to do.
Great! Now that we have an understanding of the
different types of simple machines, let’s see if you were paying attention. Drive
on over to http://home.earthlink.net/~kandyhig/sm/cross-p/cross-3.htm and complete the interactive crossword. Be
sure to print out a copy!
along…Here’s a fun experiment to try on our trip. See if you can
balance frogs. That’s right! Try
your hand at balancing frogs using a lever at http://www.sofweb.vic.edu.au/steps/students/5%2D6years/machines/frogs.htm . You may need to download some software
called Shockwave to get this program to work. Wait a few seconds to see if the
program will load. If not, just follow the prompts on your computer. Try balancing a couple of frogs, and then let’s move on. There’s
so much to see on our field trip.
Jump off the bus and take a look at this: http://home.earthlink.net/~kandyhig/sm/popmap/rubemap2.htm . See if you can identify the simple
machines in this picture. To check your answers, scroll the mouse over the numbers
to see the answers – pretty cool huh?
Hop back on the bus (think about all of the simple machines that you could find on our
bus) – we’re heading back. Tell your neighbor in the bus seat next
to you something you learned today that you didn’t know before. Remember
simple machines are everywhere!
