This Friday, June 18, we’ll explore the critical area of ââengineering in our new video series for kids: Summer School with Live Science.
In this week’s edition, Live Science producer Diana Whitcroft will demonstrate how to build a capsule that will safely land a raw egg without breaking it. She will provide her own design to protect this delicate payload from dropping 4 to 5 feet at sea. Watch with your kids and get inspired to develop an even better device that should land even higher!
Every Friday at 3:00 p.m. EDT (12:00 p.m. PDT), Diana hosts a live science summer school, which you can find live on Live Science’s Facebook, YouTube and Twitter pages. Each week the series explores a different area of ââSTEM (science, technology, engineering, and math) through simple hands-on experiences that you and your child can take at home.
Disclaimer: It is strongly recommended that all scientific experiments, recipes and methods be performed only under adult supervision. Adults have a responsibility to handle or assist in the use of potentially harmful equipment and ingredients. Wash your hands thoroughly after each experience. Avoid touching your face and eyes when performing experiments, and wear goggles or eye protection whenever possible. Do not ingest any of the ingredients during or after performing this experiment.
Egg drop challenge: objective
Age range: 6+ years old
Build a capsule or wrapper to secure and successfully land a raw egg without falling to the ground.
First step: make plans
If you’re going to be experimenting with a landing pod of your own design (and you really should), sketch it out! First, determine the height from which you want to lay your egg. Then assess what kind of materials are available to you and go from there. Create as many designs as you want and choose one to create.
Keep in mind that it is quite possible that your egg will not survive the fall. Don’t let that put you off. Just work with another of your ideas until you get a happy, seamless Huevo. After all, we can learn as much from our mistakes as we do from our successes.
Now, students prefer the idea of ââwrapping their eggs in closed capsules like shoeboxes or Tupperware. Many people who seek higher egg shedding tend to build up resistance force through the use of parachutes. In Diana’s demonstration, she wanted to use as little material as possible by creating a paper straw barrier to protect the egg from its 1-meter trip to the ground.
Step 2: build your landing pod
How you build your room is entirely up to you and depends on the complexity of your device. Keep track of your methods so that you and your child can determine why your gout was successful (or not). In the case of our paper straw capsule, Diana found that by using paper straws instead of plastic straws and first taping the straws to the egg with clear tape and then reinforcing the connecting parts with electrical tape, she was able to develop perfect structural device.
Step 3: lay it down like it’s hot
After you’ve designed and designed your device to hold up to how high you want to fall, use a tape measure to figure out roughly how high to hold your egg before you drop it. This experience is best done outdoors. To avoid wasting an egg or making a mess, install a rag or bowl to catch any spills. Wear safety glasses and a gown or apron. To better record your results, try setting up a camera to record the fall.
Step 4: Save your results
Whether this experience was a bloody success or failure, write it down. Make it a summer project if you like, building a series of gear to see how high you can manage to land an egg, or even compete with family members to see who can do the better landing pod. The more creative you are with your designs, the more you learn.
Document this experience and send us pictures on social media or at [emailÂ protected] We would love to see your results so we can feature them in our photo gallery!
Why drop an egg?
Have you ever watched the NASA video illustration of the landing of the Martian rovers Spirit and Opportunity? Compare these landings to those of Perseverance. Have you ever wondered how we get relief supplies and general goods to devastated or hard-to-reach areas of the world? This activity is designed to give children an idea of ââhow we achieve these goals.
By participating in this extremely versatile activity, kids will effectively simulate these real world applications while learning the importance of trial and error design iteration. This is an amazing opportunity to introduce technical design to young minds.
General physics and materials science are also examined in this experiment. Whether you and your family want to drop a four-foot-tall straw capsule or parachute your egg from a two-story landing, students are challenged to design a device that will reduce the momentum of the egg. , which is converted from potential energy to kinetic energy. energy on the eggshell. When objects collide (in this case the egg with the ground), their energy and momentum is changed or transmitted. These processes are mediated by one or more forces – the force that sets the egg in motion and converts its potential into kinetic energy isâ¦ gravity. When it comes in contact with the ground or the surface, the kinetic energy has to be transferred somewhere and this is the point of impact. If the forces acting on the egg are too strong, it can crack the shell. Hence the development of these different technical structures in order to divert this energy from the sensitive payload or to reduce all of the kinetic energy (for example parachutes).
