so we're going to start science with the scientific method about the scientific method but let's do a quick refresh what the scientific method is the ordinary thing in the world answer specific question find no cell phone in your pants pocket do the steps of the scientific method Dallas Lincoln Park resources important seven times because you have two sources doing background journals and online sources that are vetted and trusted our best information from blogs and out-of-date textbook avancemos might not be reliable and is very specific here's an example specific terms informatics self Park show me what numbers are 25 or 223 just not affect the water water are you from muscle group AR so we'll talk about this process which is a logical way to answer questions we have about the natural world step of your typical scientific method has a different number of steps there's no perfect scientific method works best for your situation and it's not working still have to go back so it's always has fluid logical the process starts when you ask a question about something sir I have wed what needs to be testable you can't just do a question about for instance what is my dog thinking I call him we right now we don't have the technology to test that until our technology gets better answered with science so it needs to be a question that is currently testable so what you want to do is write this down in your notes feel free to pause if you need to the next step is research and this is a lot of people just get up and it's an important step and it said if you remember to do it so for instance when you talked earlier and was trying to find a natural frequency viral video and their question was is it true so they started doing some research came up with a plan but they couldn't come up with a plan so don't waste your time to starting from nothing research what's already know about your question learn from others who may have already conducted experiments? Answered so take a few minutes to do some research it'll save you some time in the long run on the back of your notes are some more details best source of scientific knowledge is from a journal, like magazine or newspaper the most up to scientific information we had one of these things is constantly changing because we're constantly learning more and more technology things that are in old books or are old text so only at LOL he can't hear it to ask about the best source for scientific research it's a scientific journal Next Step once you've done the research then you consider your make a hypothesis an educated guess about the answer to your question score prediction easy to measure and not based on a non testable opinion away from opinion so we want the best we can possibly do measure with things that are going to be the same no matter who takes the measurement on the back if then statement is your best bet why you put this is if independent variable and the independent variable is what the scientist change will talk more about that later you're dependent variable dependent variable is the data or effect that you measure or you can't talk more about this later on but that's that for a hypothesis if-then statement experiment hypothesis your educated remember it's only educated he's done your research first then you can design a way to test it out so your experiment is how we do this inside it's designed to test the hypothesis should be up there tests that change cheated by you and be able to be repeated by others the magic number of the reason why if you get differ what does the first two times the most answers two types of variables independent chicken the variable that a scientist changes I change dependent variable is a variable that is dependent on the independent the Jada effect that you measure or you can't independent dependent go to terms are going to be extremely important so well so much dependent variable is the account ways to groups in an experiment the control the group is like it was whatever change you're looking at used to be the independent variable have been applied you're experimenting to see the effect of the independent variable is the group that done to it so think of it like this you want to test the effect of fertilizer on plant growth independent dependent variable that I measure or would be the fertilizer plant independent variable the fertilizer will not receive the fertilizer. Your control group experimental group on the other hand will get the independent variable on it text collect data all your data and observations in a journal or some kind of record keeping device recorded use correct measurements something to tops of data data that's letters will help you bubble letters another word not very precise and it can change based on measurement so think it's words as letters 5 cm 24 kg it took 4.8 seconds that's the best type of data because it doesn't matter record that data it should be the same where qualitative is more opinionated okay you can get good information from you need to analyze that data so organize and analyze your data it may help to use a chart or graph to help you visualize your data did you get any Annex results can you write your conclusion conclusion is a point when you reach a determination about your hypothesis was it right it's either supported and if it's supported or it's rejected if you rejected your hypothesis you need to report your findings that same question can either do your experiment so regardless of your hypothesis if it was right or wrong now you have information to share it could be a report to your classmates science project or even a scientific journal and that's it. you got some general information we will be talking more about this stuff later on love you guys
