for Lesson 2: Timing Charts for a Pencil Falling: Map the Force of Gravity

This first page shows how different objects fall; the only real difference is how long it takes and the space the object covers when it falls (is it a tall redwood tree (100s of feet) or a chopstick (6 inches)?):

This next chart is non-specific; just a general chart to show the process. Each line indicates the exact place where an image (in this case a pencil) will be drawn. Draw one pencil on one piece of paper. 7 pages, 7 pencils. Each pencil is drawn in a  new location, so that the sequence of images will then create "animation". This is a trick of the eye, known as the "persistence of vision". They are actually single images which together form a "motion picture". That is, pictures in motion, also called a "movie"!
This is a chart for a pencil falling. Draw only the straight line first, NOT a pencil or straw. Test the drawings in Flipbook to see the "movie" , that is, the movement. This is called a "pencil test". After you see that the motion works, you can draw a pencil or straw ON TOP of the line you drew, then scan those drawings into Flipbook. I will give you a demo of Flipbook when you are ready.
It can vary from 7 to 10 drawings. The pencil is a light object. Maybe leave out  #2 also: not so much "ease in" is needed. Maybe leave out #9 for a heavier impact to the ground.
The straw below is super light, so 5 or 6 drawings, at the most, will work. Follow the chart.
