Background research

The dropper popper is very simple but has energy concepts to understand. Some concepts are kinetic and potential energy along with stored elastic potential energy.The balls shape itself has a connection to the type of energy that is being released which is kinetic energy basically how fast it can bounce and bounce back to its original shape. For this project i will drop the ball from a height of a meter and see if the height affects the potential or kinetic energy it has and can released.

Driven Question: Why does the toy bounce higher when turned inside-out than the height from which it was dropped.

Basically the point of the project is to find out what kind of energy is used and all the different of ways it creates work which makes the dropper bounce higher than the original height.

What is needed is:

*ruler

*dropper

*flat surface

*journal

Procedure

Step 1: Find a place with a flat surface that is not carpet.

Step 2: Set a certain height that wants to be tested

Step 3: Turn the dropper inside out

Step 4: Drop the dropper and see if it did bounce higher than the set height

Step 5: Try it more than once and have fun

Safety Regulations

DO NOT DROP THE DROPPER POPPER IN FRONT OF YOUR FACE!

Scientific Principle

The principles of science would be the law of conservation of energy, energy transformations and the work the energy does to the dropper. One theory would be that the reason why the dropper bounce higher is because of elastic energy this means because the dropper already has potential energy the elastic only makes the work be done faster and transform the energy into kinetic elastic energy.
