Motion is the act of changing position or traveling from one place to another. Motion is a type of energy that an object has when it moves. Motion can be seen in everyday life, from a bouncing ball to a flying bird.
Motion: The Power of Movement
Kinetic Energy: The energy an object has while it is moving. Inertia: The tendency of an object to stay still or keep moving in the same direction. Friction: A force that opposes motion when two objects rub against each other.
Concepts:
The fastest motion ever recorded is the speed of light which is 300,000 km/second! A rocket's engines use the force of motion to propel it into space. Humans have been using motion to travel around since the invention of the wheel!

Brain break: Create a drawing of a robot with at least 5 arms of different lengths, each arm holding a different item. The robot must also have two eyes, one blue and one green.
