As the bell rang the students walked in eager to learn and took their seats. They were first instructed to hand in their “I wasn’t speeding” projects that were assigned over the weekend. After that Mr. Manning told the class to do the Daily Question on the board, it was, **Kinetic energy is an active or moving form of potential energy. Does an object need to be stationary to have potential energy?** After the class had a few guess and explanations, the right answer was said, **No, as long as there is mass, gravity and some height.** Next Mr. Manning had the class review page 18, which was also homework, together as a class. The class obviously knew what they were doing because they flew through the worksheet with very little problems. He then explained the conservation of energy and how it was showed in an equation like: ETOT= Ek + EP. Than the daring Mr. Manning explained this by using a bowling held from the ceiling. He pulled it back to his chin and released it and explained how as it got to the bottom it had lost its potential energy and gain its kinetic energy. Then the opposite happened as it rose again. Upon returning to his possession, the physics teacher himself forgot the rules of physics and flinched to the bowling ball, thinking it was going to hit him in the face. He then did it again, this time not flinching. Then convinced he showed a video and a song one of the groups had done for their project.
