 So this is a quick video to show you about how to make a physical model of one of the moon phases and I've got a ball and I'm using just a paper plate to keep it from rolling off my chair and I've got some sunlight coming in the window Which gives me a nice bright light Now you may notice that the light changes a little bit because we've got some clouds going over the sun here and now But it's still bright enough to show what I need to show So what I've got here is that when I look at my ball I see part of it lit and part of it dark If I move the camera relative to the ball I can get different portions of it lit and dark and These represent the different phases of the moon So the one I'm going to highlight for you right now is this phase Which would be a crescent moon phase So for your videos you will actually not create a video You're just going to take a static picture and you can hold it or do something like I'm doing where you leave it Sitting still and move the camera Somehow or another you need to get your ball into a position Where you can see one of the recognizable phases of the moon and be able to list that
