Sand Bag and Motion Man Activity

The Moving Man of Science
--- For this activity we recorded position, time, instantaneous and average velocity, acceleration, and inertia.
The graphs on top represent a change in distance over time which is equal to a constant velocity.  V=x/t
The graphs on the bottom row represent the change in velocity over change in time- which is acceleration.



For the following graphs we plotted all of our data and calculated the slopes for each trial.










Race Cars
Tennis Balls



Newton's Laws of Motion

First Law of Motion: 
An object at rest or an object moving at a constant velocity will remain constant unless acted upon by an outside force.
(Insert Picture of Box of Joy and Earth) 
 









Second Law of Motion:
Force = Mass x Acceleration







Third Law of Motion: 
Every action has an equal and opposite reaction. 



Energy:
 We learned that energy is conserved as kinetic and potential energy and are inversely proportional: as one increases, the other decreases.

SBG Sheet

We used Strand 1 in the classroom when deciding on what project we were each going to come up with- involving candles. We all had previous general knowledge about the uses of candles so we built ideas branching from there.

Strand 2 was met when our group made a hypothesis about how we thought our wick would burn faster if we increased the amount of wax we took away from the candle. We took our previous knowledge and applied it here.

We met Strand 3 because before beginning a completely new assignment, our Professor (Matt) helps us reflect on what certain ideas and concepts really mean to us. After collecting data involving the sand filled balloons, we were able to come up with explanations as to why or why not it wasn't very accurate.

Strand 4: As far as participating in scientific debates goes, we have not exactly addressed that stuff yet. However, we are all usually willing to ask questions when we need to.
