Egg drop project physics

In basic terms, an object that is in motion will stay in motion unless an external force acts upon it, and an object at rest will stay at rest unless an external force acts upon it.

When it comes time to test the projects, we give our sacrificial eggs a kiss and a hug for good luck before they are carefully placed into their packages to be hopefully safely delivered to the ground. Inside the box, soft padding cushions the delicate cargo.

They have the freedom to design their own project but are constrained by the materials provided and the time allowed. It is intended to teach students about the relationships between force and momentum.

A common drag reducer is a parachute made of paper, cloth or plastic. The parachute may be a simple sheet or a complex design that allows for some air flow.

Students are given an egg to drop from a high point such as the roof of the school onto a hard surface such as the parking lot.

I usually give students about 45 minutes of pure build time.

I have used it for a number of years, made some adjustments along the way, and think it's finally time to share with you. From this experiment, students also learn to form and test hypotheses and write up their observations in an organized way. Cushioned Box One of the simplest egg drop designs is a cushioned box. This does not include the time taken to hand out materials. It becomes clear from Newton's Laws that in order to minimize the force experienced by the egg at impact, students designing the egg carriers must increase the time over which the egg is brought to rest or decrease the egg's velocity at the time of the crash. Teachers often couch the project as a competition, giving prizes for effectiveness, innovation or artistic merits. Then comes the moment of truth. The students rush down the stairs with bated breath into the garden to determine the fate of their eggs and cautiously remove them to see if they were successful in this challenge.

Egg Drop Project Kids were instructed to bring in materials from home for their egg contraptions. This does not include the time taken to hand out materials.

They recored their designs on our free printable recording sheet. The egg may be placed loose inside the box or attached to an interior structure. This is a simple, yet effective way to asses what they know and are able to do and aligns perfectly with the motion and forces standards. Updated April 25, By Mary MacIntosh The egg-drop experiment is a physics class staple where aspiring mechanical engineers can test their design skills and creative thinking. I've taught 6th, 7th, and 8th graders. They have the freedom to design their own project but are constrained by the materials provided and the time allowed. References Discovery Education: Forces and Motion About the Author Jennifer Komatsu is the founder and director of Minnesota-based greyhound rescue shelter, producing content for the organization's website, blog and newsletters. They are calculating mass, speed, velocity, momentum, force, and acceleration and having fun at the same time. To ensure that the dart flies in the correct orientation, attach an aerodynamic nose cone and fins. This does not include the time taken to hand out materials. They try one more time with hope that the modifications worked in their favor, so they can avoid cleaning up egg yolks from the garden floor! Upon impact the elastic stretches, absorbing the force and saving the egg. If you are looking for a physics experiment, project or a science fair idea that engages the engineering mind and skills of your students, I would highly recommend this fun and egg-cellent project that is sure to be a crowd pleaser! After constructing their contraptions, the class examined all the other egg containers created.

I force them to build and test in two. They are given weight restrictions for the project to ensure that they are not merely packing the entire design with lots of cotton or paper.

Successful egg drop experiment

I usually hand out the materials and give them some planning time I have used it for a number of years, made some adjustments along the way, and think it's finally time to share with you. For some, this moment is met with shrieks of joy and relief, while a few are disappointed and curious as to why their design outcomes did not match their expectations. The students discussed why certain contraptions did or did not work. An increased surface area on the carrier, such as a flying disc shape or a parachute, will cause the egg to hit the ground at a lower speed. The materials are cheap and easy to acquire which is a recurring theme on my teacher budget materials are on the next page. The Carrier In order to decrease the egg's velocity upon impact, students must design their egg carriers to have increased air resistance. Inertia Newton's Laws of Motion are the basic principles illustrated in the egg drop experiment. They must design a carrier for the egg to house it during the drop. The students can modify the carrier by adding wings, parachutes, foam interiors or even marshmallow cushions. Often, this design requires an oversize contraption which may be against the rules of your specific competition.

You will want to find an area that is at least 4. I've taught 6th, 7th, and 8th graders.
