Elastic band forces experiment.
Pull the box and elastic band back to the first line drawn on the paper.
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.
The turning of the paddle propels the boat through the water.
Making vehicles move science experiments we used carbon dioxide released from a baking soda and vinegar reaction to power a bottle boat.
A great experiment for kids for exploring air pressure.
Place the elastic band around the box holding in down either side using your fingers.
This science activity is perfect for science.
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.
Force movement experiments that use easy to get household materials.
Set up your apparatus as shown in the measure the length of your spring without any hanging masses.
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.
So for some cases the rubber band.
