_*Simple Machines Around My House*_#4




We have been studying simple machines in STEM. We were assigned homework that we had to go home and take a picture with all 6 of the simple machines.
-My first picture is of me with the pulley. This pulley is part of our garage door. It lifts the door (the load) with the effort of the engine.










-The second picture is me with a lever. The lever is a shovel and it helps dig holes.








-The third picture is me with a srew. The screw holds the hinge onto the fence post.







-The fourth picture is me with a linclined plane. I'm sitting on the steps to represent it helping me to reach the front door easier.








-The fifth picture is me with a wedge. The wedge i chose was a saw. The saw cuts through the wood or whatever it is cutting.












-The sixth picture is of me with a wheel and axle. As you can see i chose a car tire of my sister's car. The wheel helps the car move smoother by rotating on its axle.

Simple Machines 2_*#3

In class we were told to draw a picture of 3 simple machines, pulley, lever, and wheel and axle.









For the pulley I choose to draw an elevator. The load is the pig inside the elevator, the fulcrum is the top of the wheel. The effort is the monkey in my case pulling on the rope.








For the lever i drew a teeter toter. the fulcrum is the pyrimid holding it up and the load is the high up child and the effort is the girl pusing with her legs to lower the load.


For the wheel and axle I choose to draw a fan. The axle in the middle is the effort the blades are the fan.


The next picture we drew was the other 3 simple machines.


The house with stairs is an example of and inclined plane. The stairs are and inclined plane. The load is whats being lifted by the stairs. The effort is the force pulling the load.


The wedge is the knife. The load is whats getting cut. The effort is the force behind it.


The screw i drew is an example of a a screw. The effort is the force behind it. the load is what its driving into.
