Station 4
- Balanced Forces: balanced forces are when there is an equal amount of force on two parallel sides of the object.
- Unbalanced Forces: this is when the force n one side is stronger than the one on the other.
Station 3
Prediction: We predicted that the marble would keep going around the plate if we applied the right amount of force to the plate with the section cut out of it.
The marble goes around the plate without touching the edge because it was
The marble on the cut plate flew off.
The marble goes around the plate without touching the edge because it was
The marble on the cut plate flew off.
- The edge of the plate makes the ball stay inside the plate. it also doesn't allow it to touch it.
- This activity models the solar system by showing that the sun has a gravitational pull that keeps the planets in orbit without touching it.
- The Earth's gravitational pull keep the moon in orbit around the Earth.
Station 2
Station 1
The ball flew up and hovered over the blow dryer. The ball moves around a lot when it's on high.
- The two forces that were exerted on this ball were gravity and air.
- The two forces are balanced most of the time. Sometimes when the ball is off the center point, it isn't balanced though.
- The object stays stationary when two forces are balanced.
- When forces are unbalanced the object will move towards a specific direction.
