Hello, this is mister sand tree. With a bunch of silly snakes. So for number one, we have to describe the parts of an experiment. So the first one is a hypothesis, a hypothesis is an educated guess. I also sometimes like to describe it as a test of statement. So testable it has to be able to be tested. We also like that you represent it in an if then statement. So you'd say something like, if mister century talks like a snake for an entire video, then all of his students will be really annoyed. For independent variable, that's the thing in the experiment that the scientists chooses to change. This is the one thing the scientists changes by themselves. And the only other thing that should change in your experiment would be your dependent variable, which is what you're not changing. So on that dependent variable, it's the part that's being measured. It's the part that changes in response to what you did. It changes in response to the IV, which is independent variable. The control is the part of the experiment that leaves out the factor that is being tested. It's the original thing or condition. It's the norm. It's used for comparison. So a tip I've gotten from miss makov on remembering the control is that you take your independent variable and you put no not or normal in front of it. So if you were testing different detergents on shirts, your control for that experiment would be no detergent. Constants are the thing that stays the same throughout the experiment. So the experiment is fair dependable and reliable. You want to be sure that you only change your two variables because if you change anything else in your experiment, you're not going to know if your results are because of the independent variable or that other thing that you randomly change everything else should be the same. Number two is experiment is the experiment part is not on the video but the answers are going to be right here so you can just reference the experiment on your study guide. Possible hypothesis if Nick records how much time suave pantene X and crew jail holds his hair, then he predicts acts will hold his hair in place the longest. A control for that experiment. If you use the no knot or normal, this would be his normal hair gel, which would be suave, so that's what he normally uses. In this experiment, the independent variable that's the thing he changes is going to be the different brands of gel. It's the one thing he changes, and that is dependent variable when he expects to change because of that is how long the gel holds his hair in place. For this experiment, lists three constants, here are some listings you could possibly have ones besides these as long as it's something that's not one of your variables and something that should be kept the same you are good, so we got amount of gel used, same hair care routine, same hair testing, same length of hair, same sports played, same kind of general environment, same hairstyle, no whipping or shaking hair, I guess you would keep that about the same, and then school schedule, something as small as that could maybe change your outcome. So you got to keep them constant. So again, for number three, the actual experiment is on your paper. This is just showing you what I'll go on the table, so please look over this, ask questions if you got them. Possible hypothesis from adding this experiment is that if she listens to rock country none and pop, then rock will cause her to run the fastest. That is her testable statement that's her educated guess. And this experiment wants to control the controllers your no, not or normal. So for this case, it would be no music. That'll be the control. And then in this experiment, what is the independent variable? It's going to be her either changing the type of music or having no music because that's what she's changing, right? In this experiment, what is the dependent variable that is the thing that's going to change because of the independent dependent variable. And that's going to be how much time it takes her to complete 5 miles. Time she completes in 5 miles. At least three constants again. So we got the same track courser trail because things like incline can change if you change the track. Same background noise besides the music, her health. That should stay constant. Same clothing, same kind of weather, same sleeping conditions. You're not going to run as far as you don't get as much sleep, right? No ads during run during, I guess if she's listening to Pandora or something like that, same sound equipment, same time of day, same diet or time eating in the same length of song. Should all be constant. So this experiment is given to you again, you've got to list things that are not fair about it are not constant and then say how you can make them constant. So one was that Sam was busy all week. Marty was not Marty has a personal trainer, Sam does not. That's not constant. Marty had a different diet his was healthy, I guess, sams was not, and then they only did one trial. They should have three or more, right? Sam was busy all week. They should have the same workload that's going to mess with their results if it's not constant. Marnie had a personal trainer while Sam did not. Again, this should be the same thing she'd either both have a personal trainer or neither of them should have it. Marty had a healthy diet again. Either Sam needs to eat healthier or Marty to eat unhealthier. Where's the snake in this one? There he is. Looks like he's hiding. Once again, we are 6th grade science. This is mister hawks. Mister hine. Misses maykov, mister Magnussen and this guy, see you later.
