Simple Machines

Our Energy Unit Continues.
We continue to explore energy by learning about Simple Machines.  Today we are learning about Levers.  

Building Our Cars

Today we build our cars!  It was crazy.  After we build our cars we began to do our investigation.  First, we wrapped the rubber band around the axle three times (added potential energy) and launched our car.  Once the car stopped we measured how far it went.  We did this three times, then we wrapped the rubber band 6 times and measure the distance it rolled.  (Kinetic energy)  We ran three trials of this as well, then we move on to 12 times and recorded our data.  Tommorrow we will graph our data. 
Qustions to consider:  When you released the car, what kind of energy did it have?
In which trial do you think the car had the most energy?

Qustions to consider: 

When you released the car, what kind of energy did it have?

which trial do you think the car had the most energy?

is your evidence that the car had the most energy?
which trial did the car have the most kinetic energy?

In which trial did the car have the most potential energy?

In Time

Just saw the movie In Time with Justin Timberlake and Amanda Seyfried.  Interesting movie.
In the future, genetic alteration has allowed humanity to develop a system where individuals stop aging 25 years after birth. Due to over-population concerns, time has replaced money as the standard currency and people must acquire more time through labor and commercial means after turning 25 years of age, or die within a year. Each social class lives in a different area called a 'Time Zone'. The poor live in the ghettos of Dayton and work each day to earn a few more hours of life, which they must also use to pay for everyday necessities. The rich live in the luxurious New Greenwich, and can live for centuries to millenia based on how much time they have accrued.

First Day of Conservation of Energy

Today we started our Conservation of Energy Unit.  The bowling ball video was pretty cool.  I would love to try that in our gym!!  

Here is your Take Five Question for today.  Please use the white box for post a comment to answer the questions.  After you type your answer in the box, click the button that says post comment below the box.

1.  What does the Law of Conservation of Energy State?

2.  What are the two kinds of Mechanical Energy, giving an example of each.

First Day of Teaching Conservation of Energy Unit

Today we began our new unit.  The bowling ball video was pretty cool.  I would love to try it in the gym of our school. 
Here is your take five question for today.  Can you tell me the two kinds of mechanical energy?  Give an example of each.

Energy

This week is the begining of our new unit, Energy.
