The turning of the paddle propels the boat through the water.
Elastic band forces experiment.

Explode a watermelon using just rubber bands.
How far can the stream of water go.
Firstly by pulling back the rubber band racer you stretch the rubber band thereby storing energy also known as potential energy.
Set up your apparatus as shown in the measure the length of your spring without any hanging masses.
Store up energy in an elastic band to make a cotton reel car move.
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.
Remember the angle and height at.
So for some cases the rubber band does indeed act like a spring.
This science experiment applies multiple ideas in classical physics all in one fun little stem challenge.
More elastic band powered experiments.
Force movement experiments that use easy to get household materials.
Discover science activities by educators that teach you how things really move.
How to build a rubber band force scale.
Place the box on the dot in the middle of the paper.
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.
Slightly more simple and much more powerful is our balloon powered car.
Elastic bands are great for exploring elasticity and learning about potential energy.
As you wind the paddle with the elastic band the band stretches storing up energy.
This science activity is perfect for science.
A great experiment for kids for exploring air pressure.
Shoot a rubber band by hooking it on the front edge of the ruler then stretching it back to 10 centimeters cm on the ruler and letting the rubber band go.
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.
This is nice especially since in the past i used a rubber band to make a diy force probe.
Making vehicles move science experiments we used carbon dioxide released from a baking soda and vinegar reaction to power a bottle boat.
