Investigating Potential Energy

We made a ramp with a slotted ruler and our science books. We measured the ramp's height and rolled a marble down the ramp into a cup. We measured the distance the marble moved the cup. We recorded our data and made inferences.

 

The higher the ramp was the farther the cup moved. ...Todd

We cooperated and worked together as a team and we had fun. ...Zach

We each did diffrent things, so it was more fun. ...Jeremy

The higher the ramp was the more potential and kinetic energy the marble had. More work is done if the marble goes faster. ...Jessie

As you move the ramp higher the cup and marble go farther. ...Ashlie

The higher the ramp the marble had more kinetic and potential energy. More work is done when the ramp is higher. ...Taylor

My predictions was not close at all. I predicted the cup would move 3 cm with 4 books but it really moved 5.5 cm. ...Alexis

One time I was close prediction, but one time I was way off. ...Cameron

My predictions were pretty close, like I guest 20cm, but it was really 16. ...Maeve

 

I would use a heavier marble to make the cup move farther. ...Michael S.

We used the big marble. The big marble has more mass so it made it go faster. ...Jeremy

More work was done when we used a bigger marble. ...Nathan

By putting the ramp higher there is more potential and kinetic energy wich made the cup move. It affected the marble by making it go faster. ...Ashley

The higher the ramp the more potential energy the marble has. ...Paul

I would like to do the same experament over, but use a bigger marble. ...Brooke Ann

When we raised the ramp the marble did more work because it had more kinetic energy and it had more potential energy. ...Nolan

The higher the ramp the marble had more kinetic and potential energy. More work is done when the ramp is higher. ...Taylor

I think if the marble weighed more it would go farther. To prove this I would use a heavier marble and keep everything the same during the experiment. ...Duane

We measured together and we also took turns rolling the marble. ...Ashlie

No one in my group listened to me except for Brooke So. ...Lauren

We cooperated, worked as a team, and had fun. ...Travis
