 This video covers part three of lab eight for my physical science students and this is a special version of the video being created just for the spring 2020 students Now you can see I've gotten GIMP opened up here, and I've already put my image in This time around for my spring 2020 students I'm not going to make you do the measurements yourself Normally they would have already had a time in the semester to get the GIMP program set up on their computer and make sure they know how to use it For some of you you're working under difficult circumstances with very limited internet So I'm going to go ahead and make some of these measurements for you I've already got it on my little measurement tool here. And so to make a measurement. I need to click and drag Now the first measurement that you need to make is for question 3.3 and It's measuring from the Sun To the point on the orbit, which is closest to the Sun, which is going to be over here You're actually answering a question about that in 3.2, but I'll let you think about that one I'm going to zoom in just a little bit so I can make some more accurate measurements When I measure from the Sun I click and drag Out to the place on the orbit here Where that dark line is and then I can come down here and view how many pixels that was So this measurement here, which you can round off to a hundred and eighty four if you want to It's going to be your measurement for three point three your perihelion distance Question three point four has you measure from the Sun to the furthest location away So I'm going to shift this just a little bit And we're going to measure from the Sun Now you notice it started on this you just got a click to sort of cancel that one out and then go from the Sun To this point further away and then you'll come down here again and see how many pixels that one was And again, you can round this off if you'd like to to about 305 pixels The next measurement you have to make is the entire major axis and This major axis I said is the dark dotted line. So that's going to go from this side All the way across Over here to this side and again getting it as close as I can but there might be a little bit of air and That's going to be somewhere right around 488 pixels, let's say The last measurement you have to make for question three point six is the entire minor axis And that's the light gray dots. So that goes from this spot on the orbit all the way I crossed over here to this spot on the orbit and That's going to give us a value of four hundred and maybe seventy four pixels Those are your measurements that you'll put into page five of your lab report To answer questions three point three three point four three point five and three point six It's then going to ask you some questions about those measurements and there's one small calculation you need to do and I'll have some other information about those in a different video
