This Friday (June 18th), the new kids video series “Summer School with Live Science” will explore key areas of engineering.
In this week’s article, Live Science producer Diana Whitcroft will show you how to make a capsule that will land a solid egg without breaking it. She offers a unique design aimed at protecting this delicate payload from a drop of just 4-5 feet. Take a look with your child and get inspiration to design better gimmicks intended to land from higher heights!
Every Friday at 3:00 pm EDT (12:00 pm PDT), Diana hosts a summer school with live science. Live Science Facebook, YouTube And twitter page.Every week, the series explores different areas of stem (Science, Technology, Engineering, Mathematics) Through simple hands-on experiments that you and your child can follow together at home.
Disclaimer: All scientific experiments, recipes, and methods are highly recommended to be tried only under adult supervision. Adults need to handle or help with potentially harmful equipment and ingredients. Be sure to wash your hands thoroughly after conducting the experiment. Avoid contact with your face or eyes when conducting experiments, and wear eyeglasses or protective goggles if possible. Do not take any ingredients during or after this experiment.
Egg Drop Challenge: Purpose
Age range: 6 years and over
Create a capsule or package to hold the raw egg in place without breaking it from the fall and land it normally.
Step 1: Create a blueprint
If you plan to experiment with a landing capsule of your own design (and you really should), sketch it! First, determine the height at which you plan to drop the eggs. Then evaluate the types of material available and proceed from there. Draft as many designs as you need and select one to create.
Keep in mind that your eggs may not be able to survive the fall. Don’t be discouraged by this. Simply work with another of your ideas until you land a happy, fracture-free huevo. After all, we can learn as much through failure as we succeed.
Most students like the idea of putting eggs in sealed capsules such as shoe boxes and Tupperware. Many people looking for higher egg drops are enthusiastic about using parachutes to create drag. In Diana’s demonstration, she set out to use the smallest and simplest material possible by creating a paper straw barrier to protect the eggs from a four-foot move to the floor. ..
Step 2: Build a landing capsule
How you build your work is entirely up to you and depends on the complexity of your contradictions. Log your method so that you and your child can determine why your drop was successful (or unsuccessful). For our paper straw capsules, Diana uses paper straws instead of plastic straws, first by taping the straws on the eggs with clear tape and then reinforcing the connections with electrical tape. We have found that a lot of engineering can be done on a comprehensive and structurally sound device.
Step 3: Drop it like hot
After designing and designing the device to withstand the desired drop height, be sure to use a tape measure to get a rough idea of the height at which the egg will be held before releasing the egg. It is better to do this experiment outdoors. Install a drop cloth or tray to catch the droplets so that the eggs are not wasted or confused. Wear protective goggles and a smock or apron. For better recording of results, try setting the camera to record drops.
Step 4: Record the results
Make a note of it, whether this experiment was successful or unsuccessful. You can do this in the summer by creating a series of gimmicks to see if you can land your eggs well, or by meeting face-to-face with your family to see who can make the best landing capsules. Make it a project. The more creative you are with your design, the more you will learn.
Document this experience on social media or email@example.com.. Please take a look at the results so that we can introduce them in the photo gallery.
Why do you perform egg drops?
Have you seen NASA’s video illustrations of Mars rover, spirit and opportunity landings? Compare those landings with patience landings. Have you ever wondered how we deliver aid and common goods to the devastated and inaccessible areas of the world? This activity aims to give children ideas on how we can achieve these goals.
By participating in this highly versatile activity, children will effectively simulate these real-world applications and learn the importance of design iterations through trial and error. This is a great way to introduce engineering design to the young mind.
The experiment also emphasizes general physics and materials science. Whether you and your family drop a straw capsule from a height of 4 feet or parachute an egg from a two-story landing, students are asked to design a device that reduces the amount of potential energy in the egg. Increasingly it is transferred to the potential energy of the egg shell. When an object (in this case an egg and the ground) collides, the energy and momentum of the object is changed or transmitted. These processes are mediated by one or more forces. The force that moves an egg and transfers its potential to kinetic energy is … gravity. If the force acting on the egg is too strong, the shell may break.
