Have you ever designed your own track?

Today we conducted a mathematical investigation that involved
properties of physics.

Purpose: To Design a prototype to investigate the distance one glass marble could roll on a hard surface.

(Create a device which is going to propel on class marble to see how
far it will go.) [measure distance]

Materials:

• 1.5 metre of masking tape.
• 3  metre wooden ruler.
• 3-4 glass marbles.
• Chalk

Predictions:

1st marble: 5.30

2nd marble: 1.50

3rd marble: 5.11        

Method

Two rulers were taped together diagonally using the masking tape.
Once secure, the prototype was taken outside to the court area to
provide a concrete surface for the marble to roll on.

Our  prototype ( track) was elevated 440mm, by placing  the track
into one of the fence gaps. We rolled the marbles down the track to
investigate the distance it would travel.

Results:

1st Marble: 3.20m

2nd Marble: 2.22m

3rd Marble 2.48m

Conclusion:

That the higher the elevation of the ruler (our track) the further
the distance of the marble will travel. The power that was created by
the elevation is the physics in our investigation.
