This what I got when I Googled: "How to Swim" these are instructions on how to swim free-style. I liked the descriptions of the motions and how the body and water interact.
Step 1: Visualize a line running down the center of your body from your chin to your chest. This line is the axis upon which your whole body should pivot, and it should extend horizontally in the direction you are swimming.
Step 2: Keep your legs straight, but not rigid, with your toes pointed out, and kick up and down. Continue kicking the entire time.
Step 3: Move your arms in a windmill motion opposite each other. While one arm is extended completely out, the other should be all the way back, almost against the side of your body.
Step 4: Keep your hands flat, thumb separated from the index finger and pull the extended arm through the water beneath your body. Bend your arm at the elbow and draw your fingertips along the imaginary line down the center of your body.
Step 5: Lift your other arm out of the water and move it all the way forward as the first arm is pulling beneath you. Bend at the elbow and drag your fingertips along the surface of the water. Penetrate the water with your fingertips and completely extend the arm.
Step 6: Breathe on one side by turning your head to that side as the arm comes out of the water.
