1) Put ball on stage.
>Window >Library
Select the ball layer or create it if you don't have a layer called ball. I like to lock the layers that won't be used so that there are no mistakes. It is very important to put the ball on the correct layer.
Select the ball icon and the ball will appear in the library window.
Click on the ball and drag the ball onto the stage.
Resize the ball using the freeform tool. Select the transform tool and make the ball a more reasonable size. I put my finger on the shift key and grab a corner of the ball and drag in. By using the shift key the ball stays in the correct proportions.Then move the ball in the starting position in the players hand.

2) Tween the ball.
a)Click on frame 50 of the ball layer.
>Insert
>Timeline
> Keyframe

Your scene disappears.
Select frame 50 of the bg layer.
>Insert
>Timeline
> Frame

b)Click on the ball layer, frame 25
>Insert
>Motion Guide
A new layer appears above the ball layer.
c) Select the pencil tool. Select the smooth option. Select the guide layer. Draw a path from the left to the right. This path will not be seen when you play your movie. It is just a path for the ball to follow.

d) Click on frame one of the ball. Use the black selection tool. Make sure the magnet is selected. This is tricky! Drag the center of the bee - the cross hair or circle depending on how it is selected - to the beginning of the curve you drew.

e)Now select frame 50. Drag the center/cross hair of the bee to the end of the curve.

f) Click between the frames. >Insert > Create Motion Tween. The tween is already shown in the above two images but won't on your stage until you do this step.
g) >Control >Test movie. If the bee takes the path of the pencil line then it worked. If the bee just goes straight across the stage then try again. This is tricky so it might take a few tries. Be patient with yourself.

Save your work.

3) Put background scene in all the frames.
I'm sure you noticed the plant and vase disappear as soon as the bee begins to fly. The scene is just set on frame 1so let's extend the scene.
a) Unlock all the layers.
b) Click on frame 50 of the plant layer.

>Insert
>Timeline
>Frame.
That extends the scene.
c) Click on each layer and frame 50 and extend the entire scene

Save your work.

5) Complete the movie

Add a final touch.
