Elastic band forces experiment.
This science activity is perfect for science.
Set up your apparatus as shown in the measure the length of your spring without any hanging masses.
This is nice especially since in the past i used a rubber band to make a diy force probe.
More details at dot physics scienceblogs.
Slightly more simple and much more powerful is our balloon powered car.
Making vehicles move science experiments we used carbon dioxide released from a baking soda and vinegar reaction to power a bottle boat.
So for some cases the rubber band does indeed act like a spring.
Force movement experiments that use easy to get household materials.
This science experiment applies multiple ideas in classical physics all in one fun little stem challenge.
Elastic bands are great for exploring elasticity and learning about potential energy.
When we pull back on a rubber band we store energy in the band and this is called potential energy when we let go of the rubber band all this energy is released as kinetic energy as the band springs back into shape.
The turning of the paddle propels the boat through the water.
Remember the angle and height at.
Hang a mass of 100g on the spring measure the new length of the spring calculate the extension of the spring repeat steps 3 5 for increasing the mass in increments of 100g take note of your results in the table.
Explode a watermelon using just rubber bands.
Pull the box and elastic band back to the first line drawn on the paper.
How to build a rubber band force scale.
Place the elastic band around the box holding in down either side using your fingers.
Place the box on the dot in the middle of the paper.
How far can the stream of water go.
When you let the paddle go the elastic band unwinds to shrink back to its original size releasing the stored energy and turning the paddle.
More elastic band powered experiments.
Store up energy in an elastic band to make a cotton reel car move.
So for some cases the rubber band.
Firstly by pulling back the rubber band racer you stretch the rubber band thereby storing energy also known as potential energy.
