Ball And Sock Experiment

Bouncy Ball Experiment Aim: The aim of this experiment is to investigate the efficiency of a bouncing ball, and the factors which affect its efficiency. Prediction I predict that the higher I drop the ball from the higher it will rebound up, because it will have more gravitational potential energy the higher dropped from. As it is dropped the ball will have kinetic energy, and then when it hits the ground changes to heat and sound energy, and kinetic as it rebounds back up. The higher up...

An Experiment

FIRE RESISTANT BALLOON: Materials -    1 matchbox -    1 candle -    1 yellow colored balloon -    1 blue colored balloon -    Half a cup of water   Procedure: 1.    For this experiment, the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount...

This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different...

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed...

Physics Ia on Bouncing Ball

this experiment is to determine a factor that affects the height of a bouncing ball. The factor that will be investigated in this experiment would be the initial height of the ball. The relationship will be determined by altering the initial height of the ball prior to the release in order for the ball to bounce. The ball used in this experiment would be a tennis ball, and it will be dropped on the same surface each experiment. However, the initial height prior to the release of the ball will be...

Experiments in Electricity and Magnetism

straight after you combed it, or had your socks stick together when you removed them from the drier. This is called static electricity, but back then nobody knew how to explain it or what to do with it. Experiments using friction to generate static electricity led to machines that could produce large amounts of static electricity on demand. In 1660 German Otto von Guericke made the first electrostatic generator with a ball of sulfur and some cloth. The ball symbolized the earth, and he believed that...

Crater Design Experiment

Crater Design Experiment Aim: To see how the height in which the ball is dropped from affects the depth of the crater. Hypothesis: I predict that as the height in which the ball is dropped from increases, so does the depth of the crater (the data will be directly proportional). The scientific knowledge which supports this is that the golf ball has a gravitational potential energy which increases as the ball is dropped from higher heights. When the height increases the ball gains more gravitational...
