In this exploration, student design, evaluate, test, and also suggest improvements for a container the will safeguard their precious payload: an egg.
The classic "Egg-Drop" experiment has actually been a standard in scientific research instruction for many years. Essentially, students room asked to build some form of container that will store a raw egg native cracking when dropped native ever-increasing elevations.

There room three straightforward ways to increase the likelihood of safe dropping an egg:Slow under the descent speed.Parachutes space an obvious technique for slowing the kind speed, as lengthy as the architecture includes a method to store the parachute open. Cushion the egg so that something other than the egg chin absorbs the influence of landing. The largest finish of the egg has actually an area of waiting trapped between the egg"s two membranes. This air room forms as soon as the contents of the egg cool and also contract after the egg is laid. It accounts because that the crater you often see in ~ the end of a hard-cooked egg. Upon affect the heavier spherical yolk proceeds moving towards the ground. The compression that the airspace acts prefer an air bag because that the eggs" beneficial contents. Structure an synthetic cushioning an equipment will also assist absorb the affect of landing. The largest finish of the egg has an area of waiting trapped in between the egg"s two membranes. This air an are forms as soon as the materials of the egg cool and contract after ~ the egg is laid. It accounts for the crater you regularly see in ~ the end of a hard-cooked egg. Upon affect the heavier spherical yolk proceeds moving towards the ground. The compression of the airspace acts prefer an waiting bag because that the eggs" an important contents. Structure an synthetic cushioning an equipment will also assist absorb the impact of landing. Orient the egg so that it floor on the strongest part of the shell. The arch framework at either end of the egg is stronger than the sides. Push is spread down (or up) the arcs so that much less pressure acts on any one point. Orienting the arch downwards will rise the egg"s survival.
The Challenge:On respectable 22, 1994, David Donoghue threw an egg out of a helicopter ~ above a golf course in the UK, native a elevation of 213 meters (700 feet). He now has the record for the longest egg drop there is no breaking in the human being (all there is no an outside structure for added protection!).
Teacher Tip:You can relate the activity to the an obstacle NASA scientists had actually in building a lander for the Mars expedition Rover. Physically, it had actually to resist both the warmth of entry right into the Martian atmosphere and also the impact of landing. Strategically, they additionally had to figure out a method that the rover can right itself no matter exactly how it landed. Students love to see just how the structure they"ve developed often resembles the one conceived through NASA scientists.
demonstrate curiosity and show inventiveness.
Brainstorm in a team to create ideas.
Use problem-solving methods in building an easy structures.
Per Class:large plastic sheet/tarp/vinyl tableclothladder (optional)
Per group of 2–3 students:1 extra-large egg1 bag of products (may include cardboard cup, string, tape, balloons, straws, etc.)2 sheets that scrap paper and 2 pencils
What to be successful/unsuccessful in your design? What makes an egg a great ‘subject’ because that the drop experiments?
What to Do
Preparation:Scout out obtainable locations roughly the college for the egg fall at various heights.Make enough bags of products for college student groups.

Exploration:Challenge the student (in groups of 2–3) to develop a framework in 40 minutes that will prevent an egg indigenous breaking when dropped indigenous a high place. Brainstorm means to increase the likelihood of for sure landing your eggs.Each group gets a bag that materials, 2 pencils, and 2 sheets the scrap paper.The students cannot assemble anything for the first 10 minutes. This time is to be supplied to brainstorm and to draw a mockup of their structure on the scrap document provided.When the 10 minute is up, circulate roughly the course to ensure that the college student have thoughtfully mocked up their landers.Place the egg in separation, personal, instance egg holders and hand out to the teams. Repeat students that they cannot use the egg holder as component of your design.Drop the eggs from a launch allude into the fall zone, which is protected by a plastic sheet, ensuring the each lander is dropped indigenous the very same distance.Once dropped, the students examine out the egg to check out if the has broken or if there are any cracks.The team whose egg survives the highest drop wins.
Teacher tipsThe teacher need to be the one to launch the egg to for sure fairness and also to mitigate the risk of injury (if dropping indigenous a high distance).Many the the gives in this activity can be accumulated and reused!
