Simple Machines At Home

This is a toilet paper dispenser.  It acts as a wheel and axle.  Toilet paper is the wheel and the axle is the removable part that holds the toilet paper in place.

These two pictures are of my garage door.  It shows how it has a pulley system to lift the door.  The chain is what gets pulled.


This is a ramp to get into my garage.  This is considered a wedge.  

This is my can opener. It turns a can around to open it.  This would be considered a wheel.

This is a picture of my scissors.  They are considered two wedges going in the opposite direction.  

This is a picture of one of my door hinges.  I wasn't sure what simple machine this was so I looked online and it said it was a second class lever.


This is a picture of my stairs.  I also looked this one up on line and it said this was a Incline Plane.

I never thought about the things I use at home that are considered simple machines.  Most of what I use makes my life so much easier.

Reduce, Reuse, Recycle

When I go to the store I take my reusable bags with me.  This helps me to reuse the bags I have and reduce the amount of plastic bags used.  This also helps me carry more items because they are much larger than the plastic bags. 




I always try to use my reusable water bottle.  It keeps my water cold pretty much all day.  I also find it easy to wash so its not hard to reuse a water bottle.
 To clean my windows I usually reuse newspaper with windex and sometimes vinegar.  I find this as a great use for old newspaper and I don't use all my paper towels.  Plus it helps get the windows clean.



When I have items to recycle I usually take them to my parents house since they have a large recycle bin.  I save our cans and boxes and put them in the bin with my parents items.
