This post is part of the 31 days of STEM activities for kids series. Find the other posts here! This week, we are focusing on engineering projects, the “E” in STEM.
When I was a kid, we had a book about this egg drop engineering project, and ever since then, I have wanted to try it. We live on the third floor, so we have quite a long drop from our balcony, which is perfect for this experiment. If you don’t live in an apartment or have a second story, you might be able to test your eggs by tossing them off your roof.
Egg Drop Engineering Project
The goal of this project is to create a container that will safely deposit a raw egg onto the ground when it is dropped from something high.
- Raw eggs (buy some cheap ones so you can make multiple attempts)
- Various containers and padding
- We used bubble wrap, cloth diaper inserts, plastic trash bags, plastic food containers, string, tape, plastic bags, and egg crates
Monkey thought she could create a little nest for the egg like in a hot air balloon. She used the trash bag as the balloon and placed the egg in a plastic ice cream dish. She padded the bottom of the egg, but not the sides.
When we dropped the egg, it fell onto its side and exploded.
Monkey expanded on the hot air balloon design, but this time, she made the container holding the egg larger. She padded the egg in several layers of padding, including a plastic bag blown up to create an air pocket. She taped the container to the trash bag balloon.
When we dropped this package, it still fell pretty heavily (I’m not sure the balloon part was necessary), but the padding prevented the egg from breaking.
I love the egg drop engineering project because it involves creativity mixed with a bit of physics. There are probably hundreds of designs that will keep the egg safe. With a group of children, it would be fun to see what differing designs could be successful in keeping the eggs from breaking.
Watch our results below!
If you do the egg drop engineering project, share your results with us! We would love to see your creations!
