	5 out of 6 and i totally forgot about the one i missed. I kept thinking scissors for some reason.

	Wheel didn't take for Wheel and Axle? hmmm...oh well, got all the others except for wedge.

	Axle is imperative for wheel and axle. It's the rotary force and torque that produces the mechanical advantage.

	is there really a difference between inclined plane and incline?

	Wouldn't ramp count for inclined plane?

	Mr. Hahn (my 5th grade science teacher) would be disappointed with my performace in this quiz

	@ truth...thats what I tried too.

	Forgot about wedge and forgot the "and axle" part of wheel >.

	How about "slope" for "inclined plane"?

	too specific for a few of them. But I used 'ramp' and 'wheel' back in grade school

	MrEnglishman:	Apr 16th, 2009 at 17:23 GMT		1 point
	@jereboam - yes, I tried "slope" too. I also only put a simple "Wheel". So 4/6 for me.

	@Jeremy... don't know about the Scientific Method but the Mohs hardness scale is in fact already here: http://www.sporcle.com/games/minerals.php

	ramp should be accepted as "inclined plane"

	DWolf:	Apr 16th, 2009 at 18:01 GMT		4 points
	@isstvan: You kind of answered the opposite of awol's question. I think he was more asking why "incline" wasn't sufficient for "inclined plane", rather than the difference between an inclinded and a non-inclided plane.

	I always envisioned a screw being in fact an inclined plane/ramp that just wraps around itself. And speaking of which, isn't a wedge (like a door wedge)also just two inclined planes whose action relies on friction rather than elevation ? I always memorized the wheel, the ramp, the lever, and the pulley as the 4 simple machines.

	Forgot the first one, and thought it was in alphabetical order by the I, not the P...ah well.

	davidr:	Apr 16th, 2009 at 18:11 GMT		5 points
	@ricainrico: Some people view a screw as a curved inclined plane but a screw converts rotational motion into linear motion, which an ordinary inclined plane doesn't. A wedge is usually thought of as a moving inclined plane — for example, the kind of wedge that you'd hammer into something to split it. So, if you push your door wedge under the door, you're using it as a wedge; if you pull the door onto the wedge, it's an inclined plane. :-)

	haha, I kept guessing wheel and axle separately. I was getting frustrated too.

	PhilSandifer:	Apr 16th, 2009 at 18:54 GMT		0 points
	I have, however, often seen "gear" listed as a simple machine as well - more often, actually, than I've seen "wedge."

	Awesome. Embarrassed by the ones I missed, but awesome nonetheless.

	Keonyn:	Apr 16th, 2009 at 19:18 GMT		4 points
	I've never seen a list different from the one provided here. A gear is just a type of wheel and axel.

	Ghostbear:	Apr 16th, 2009 at 19:35 GMT		0 points
	I suppose i never questioned it in seventh grade but isnt a screw simply an inclined plane and a wedge rolled into one.

	A lesson I learned from the mistake of another teacher: if teaching junior high kids about simple machines, don't have them do a project and send them to a computer to search the word "screw."

	Hrmph.. no internal combustion engine huh?

	maybe "ramp" should be accepted for "inclined plane" and either "wheel" or "axle" accepted for "wheel and axle"...?

	I'm a high school senior who hasn't had to think about simple machines since 4th grade science class... Got 5/6, which isn't bad for it having been so long... but I forgot wheel and axle. :/

	newenglander:	Apr 16th, 2009 at 20:55 GMT		-4 points
	I just studied these in science and tech ed, and only got three.lol

	I have to give a shout-out to the (U.S.) kids' TV show "Zula Patrol" for getting any of these - it's a cartoon designed to increase early science literacy (not that my 5-year-old cares; he just likes the stories). They just aired an episode on simple machines, and I caught it during my morning coffee. See, you never know when Sporcle will make mundane bits of your life relevant!

	I typed in ramp and wheel!

	sorry mrs palmisano (my 3rd grade science teacher)

	Daytman:	Apr 16th, 2009 at 21:47 GMT		2 points
	Ugh, I missed wheel and axle because I put wheel, and I missed pulley because I put rope and pulley. I blame my physics teacher.
