Simple machines are devices that make hard tasks easier. The document discusses four simple machines: the pulley, lever, inclined plane, and wheel and axle. It provides examples of how each machine works, such as using a pulley to lift a piano upstairs more easily than lifting it with strength alone. The document also describes a Rube Goldberg-style project the students completed that incorporated all four simple machines.

2. What are Simple Machines
Simple machines are machines that help us do
hard tasks into easy a easy one.
For example: Lifting a piano upstairs, you have
two options lift it with your strength or us a
simple machine called a pulley. This way you
will finish your job in a easier and less stressful
way.

Our 1 Simple Machine
Our first simple machine was the pulley.
In this project we used it to go down and knock
over some cards, as this happens the other
part goes up because of the weight.
Another scenario would be using the pulley to
get something from one place to up or down.

Our 2 Simple Machine
Our second simple machine was a lever.
In this project we used a lever by balancing a
ball and hitting one side of the lever to cause
the other to rise and makes the ball go along
and down.
In another scenario a lever is used as a teeter
totter which goes up and down due to the
weight.

Our 3 Simple Machine
Our third simple machine was a inclined plane.
In our project we used the inclined plane as
some kind of ramp which leads the wheel and
axle down.
In another scenario for a inclined plane is a
movers van. At the back of the truck there is a
inclined plane which is used to lower the heavy
and big appliances down instead of lifting it.

Our 4 Simple Machine
Our fourth simple machine was a wheel and
axle.
This was used for when the inclined plane
released the wheel and axle it went down the
ramp and hit the cards and ruler which pressed
the button.
In another scenario this is used for fishing,
when you bring the fish in you use the wheel
and axle bringing the sting around and the
object to you.

11. Conclusion
In this project we learned how simple machines
are everywhere and how they can help us a lot
by simply making tasks easier, hitting and
planing out was a hard because there were
many mistakes but at the end it was worth it.
The end, Thank you!
