 Do you guys know that the arms and the stick of a hockey player actually make a lever? And levers are simple machines, and simple machines help us do work. Oh, you mean like my homework? Not exactly that kind of work, unfortunately. It's a different kind of work that we do in science. Oh, I know which work you're talking about. It's the force times the distance. Exactly. Okay, so like if I move an object, if I use a force to move this object, and I move it a distance, then I've done some work. Exactly. That's awesome. So why don't we try an experiment then? Sparty, would you like to help us out? Awesome. Okay, we're going to use this hockey stick. This is for you, and we're going to use this bucket full of hops. So, Sparty, what I'm going to get you to do is hold that hockey stick at the very end with your hands, and try to lift this bucket using only the hockey stick. Do you guys think that Sparty's going to be able to do it? I don't know. We'll see. Okay, ready, Sparty? Go. Little, but that's been really hard. So I think I know what the problem is. Sparty, if I didn't give you any instructions, how would you lift this bucket with the stick? How would you usually do it? Oh, I think you'd be an expert. Point in the middle that you use to help you lift the bucket. And that's what hockey players do with their sticks, too. So to help us to show how levers are used in hockey sticks, we have Senators Ford Kyle Tourist here. He's first going to take a shot on that, putting both of his hands at the very end of the stick, and then we'll see how he does it properly. So go ahead, Kyle. Power in that one. Let's try again with the lever. Here I have a giant lever, and with it I would be able to do work, and so lift things I wouldn't be normally not be able to lift. So who should I lift? Hmm, I think I should lift you, Sparty. Okay, so we're going to have to get on one end of the lever. Okay, so who thinks I'd be able to lift him with this giant lever? Let's find out. Three, two, one. Sparty, you're too heavy. What did you eat for breakfast this morning? Hmm, a lot, apparently. All right, but I know how to fix this. I'm going to move the fulcrum of the lever towards Sparty, so my end of the lever will be longer. All right, who thinks I'd be able to lift Sparty now? Three, two, one. By using a simple machine, I'm able to do a lot more work than I would normally be able to do. Thanks, Sparty. Are you afraid of heights? I hope not.
