egg parchutes

the experience.

On y a competition occured that would set records and bring out others true competive selves. It was an interesting Friday afternoon. Groups of four or five would craft a device that would protect their "cargo" from immenent impact. Their egg. The available resources to us were not limeted so we had: cotton wool;cardboard and the ingreedient that was vital to the eggs suvrivial sponge.

The science behind it.

There are many ways that you can go about this so there are many explanations behind it. I am going to go through the most popular one in our class. The one using straws. Basicly the potential energy (the hieght of the place you are dropping it from times the wieght of the contraption) turns into kinetic energy (speed times height). If the kinetic energy adds up to more of the molecules the egg breaks. The point of the straws is to spread out the kinetic energy therefore making the molecules equall more than the energy so the egg is saved.

resources available:

cotton wool,

sponge,

silk,

cardboard,

plastic bags,

string,

cello tape.

location of where we dropped the eggs

we dropped the eggs in the year one area where blue class watched us. we took it in turns to drop our contraptions.

so if you are wondering who won every one won!
