Episodes:

• Science, Please! Force and Motion: Gravity.

  Gravity alone holds us to the earth's surface. The motion of an object can be described by its position, direction of motion and speed and in a straight line. Objects change their motion only when force is applied.

  Length:	00:00:01

• Science, Please! Force and Motion: Lift Off.

  For every action there is an equal and opposite reaction. Energy is associated with mechanical motion. Energy is transferred in many different ways.

• Science, Please! Force and Motion: Operation Lever.

  People have always invented tools and techniques to solve problems. The position and motion of objects can be changed by pushing or pulling.

• Science, Please! Force and Motion: The Force of Water.

  Unbalanced forces will cause changes in the speed or direction of an objects motion.

• Science, Please! Force and Motion: The Internal Combustion Engine.

  The engine works in four stages: a value opens and the piston lower letting a mix of fuel and air into the combustion chamber, as it comes in compresses the mixture, then, a spark from the spark plug egnites the mixture which pushes the piston down again, finally, the exhast value opens and as it comes up pushes suspended gasses out.

• Science, Please! Force and Motion: Wheel Meets Friction.

  Humans love to be on the move. When moving objects across the ground we lose a lot of energy. To reduce this loss of energy, humans, over time, have added rollers underneath. Adding an axle to these rollers creates the wheel.

• Science, Please! Heat and Cold: The Wind.

  Air is composed of molecules of different gasses. When the air is cool, the molecules huddle together. When warmed by the sun, they become more active and more scattered and lighter. Other molecules run in creating the motion of the wind.
