Science Buddies: "Ask an Expert"

I am doing the following experiment: Roller Coaster Marbles: How Much Height to Loop the Loop? I would like some suggestions for charts, tables, and graphs that I could use for this experiment. Thank you!

Hi Hannan and welcome to Science Buddies!

This sounds like a fun project! Looking at the suggested procedures (steps 9 - 14) in this project:

https://www.sciencebuddies.org/science- ... #procedure

it looks like you have 10 observations of the marble for each of several different heights of the starting point for the track.

Did you write down the heights, the horizontal distance, and the number of successful runs for each height and distance?

You could make a graph with the different heights shown on the horizontal ("x") axis and then the number of successful runs at each height on the vertical ("y") axis.

If the diameter of the loop and/or the horizontal distance changed when you changed the height, you might want to make a separate graph for those "conditions." You could even make a graph to show how the diameter of the loop and/or the horizontal distance changed as the height was changed.

Let us know if this helps and be sure to let us know if you have more questions!

Thank you, MadelineB! All the information you gave will be really helpful for my project. Thanks again!
