Egg Drop Challenge Result

After weeks of planning, building and modifying containers, children came up with their own unqiue design to test their egg drop challenge. Some of the children focused on slowing down the gravity using a parachute while others tried to minimize the impact by providing a lot of cushion, and some did both.

Here are contestants and their desgins for the Egg Drop Challenge












Each contestant’s egg was placed inside their individually designed container. Then they dropped them from the first floor plat form of the church playground.


Who’s egg survived and who’s egg didn’t?


Here are the winners of the Egg Drop Challenge: One kindergartener, one first grader, one third grader and two forth graders succeeded.


Congratulations to all children who participated in the challenge. Even though not all of the children’s eggs survived, all of their containers did provide some form of protection. Comparing with the egg that was dropped without any protection, there was a huge part of egg that were saved.


What did we learn from this experiment?



Children observed 2 major differences in design between people who have succeeded vs. not succeeded.

  1. Egg was securely positioned inside the container.
  2. Egg was well padded or cushioned to minimize impact.



Another Challenge: Making A Prediction On Teacher’s Design

Based on their own experience and learning from the previous experiment, children had to make a prediction on one of teacher’s design, whether or not the egg will survive.

After carefully examining the container, all children agreed that the egg will survive. They noted that egg is securely positioned inside the container and there is a sufficient amount of padding where there won’t be any direct contact with the ground.

The result came out as the children predicted. Thus we conclude our Egg Drop Challenge. Many Children have commented that it was one of hardest projects that they had to work on and they are happy that they were able to figure out various parts of challenge.

Egg Drop Challenge

After reading the fantastic adventure of Annie Edson Taylor, Barreling Over Niagara Falls by Nancy Kelly Allen, children were inspired by the true story of Annie Taylor who was the first daredevil to barrel down the Niagara Falls and survive in 1901. To further explore this event and expand the children’s knowledge of different materials from the previous project, we decided to do an egg drop challenge where children had to design a container using open ended materials to prevent their egg from cracking after dropped from the first floor of a building.

What made Annie Edson Taylor successful? Children pointed out that the key reason for her survival was a well planned design of her barrel. We also examined 4 other daredevils who attempted the fall and made predictions whether or not they would be successful. These daredevils used a kayak, a tin barrel, water scooter and an air filled container. Many of the children agreed that the open structures like kayak and water scooter are not good choices for the task. Sure enough those 2 daredevils didn’t make it.





Another key element of success is the science concept that the children have to understand. To help the children understand, we simply started by asking what happens when objects are dropped from the ceiling height?

Children observed that all objects fall to the ground. However depends on the type of material, it can either break, dent or maintain it’s original shape. Unlike fragile or hard materials, children noted that materials that are felxible tend to keep it’s original form after collision with the ground.


Effect Of Gravity

Now that the children understand that all objects fall to the ground, does different types of materials make a difference? 10 objects with various sizes and weights were chosen for children to think about; when they all get dropped from the same height. Most of the children hypothesized that heavier objects will be dropped faster than lighter objects.

What was the result of the experiement? The result was broken down into 2 groups, one group took less than 1 second and the other group took longer than 2 second. Thus it’s not always true that lighter the object, slower the fall. Almost all objects fall to the ground with same speed.



Then how about the same object dropped in the air with a different positioning or shape, i.e. paper horizontally vs. vertically and paper crumbled up vs. straighten?


Air Resistance/ Friction

Children experimented air resistance and friction through running across the room with:

Paper Bag Open vs. Closed


2 Different Paper Bags: big and wide vs. narrow and small


Different Type Of Kites: with cell vs. with skeletal structure


Get To Work

After learning all these scientific concepts and studying Annie and other daredevils’ designs, students were busy getting to work to create their own container design. It took many days for them to try their ideas by playing around with many different materials and also testing them out. None of them succeeded at first but learn to be happy with a small success and hope to make it even more succesful for the following day. Somedays, children got tried of trying and had to take a break by doing something else, like simply playing with toys.

Freedom To Create: Open Ended Material

Knowing your materials is the absolute basis for both science and art. You have to use your hands and your eyes and your whole body to make judgements and see potential.” The Having of Wonderful Ideas: And Other Essays on Teaching and Learning by Eleanor Duckworth.

Children were presented with many different natural or manufactured material found in the home or outside, such as sea shells, pine cones, bubble wrap, pipe cleaners, and toilet paper rolls. Uncertainty of these materials provide children with freedom or unlimited possibility of building things. And because of these uncertainty, children really have to play with materials and understand what each materials can be used. Playing around with these materials, children becomes like scientists who are constantly conducting experiments, testing ideas, and building their understanding of the world according to National Creative Center for Aging.


Children develop power when they build individual relationships with materials. When children have the chance to notice, collect, and sort materials, and when teachers respond to their ideas, the children become artists, designers, and engineers.” Weismann Topal, coauthor with Lella Gandini of Beautiful Staff.


Many of the children came up with various creations of their own. Often these creations inspired each other and they would copy or come up with something that worked even better. There were collaboration among students where they worked together on create somthing or help each other to provide feedback or physical help.


Musical Instruments:

  1. Drums: Students discovered that different materials resonate different sound when you hit them.


2.  String instrument: Students discovered that different rubber bands have different tension which creates different sound.

Paper Engineering: Pop Up Card Creation

Inspired by Lovepop Cards, an intricate 3D paper sculptures designed by 2 naval engineers right here in Boston on cutting-edge software and then handcrafted in the Asian art form of sliceform kirigami, Lin Learning Center took on the challenge of creating a pop up card of our own.

Paper is a wonderful material to work with. It is flexible and versatile. It is easy to cut, bend and glue together and at the same time, it can be strong when it is folded. Understanding this characteristic of paper and the mechanism of how to fold, cut and make crease, children were able to create a simple to sophisticated paper invention.

Every week, children explored and learned 6 different mechanisms that we called them patterns:
1. Conversing crease
2. Parellel crease
3. Right angle V fold
4. Acute angle V fold
5. Symmetrical parallelogram
6. Asymmetrical parallelogram

Making patterns require a strategical cut, fold and shaping of paper. Without a precise finger fine motor and understanding of angles and lines, paper would not work in 3D. After learning how to create mechanism that works, children used their creativity  to come up with their own 3D designs. Some of them were able to combine 2 or more patterns and some of them even came up with their own pattern.


Collaboration during the project:



Challenge Of The Project

Children were asked to submit their final pop up designs for competition. Voting was open to parents, teachers and other care givers. They were asked to vote on 2 categories, best design and best mechanism from 2 groups, older and younger children.


Here is a closer look on the older children’s  group:


Here’s a closer look on the younger children’s group:


Challenge Winners 

Huisung was voted for both mechanism and design on the older children’s group. Nathaniel was voted for best mechanism while Lena was voted for the best design on the  younger children’s group. They were awarded with Lovepop card of their choice.

We’d like to congratulate on all children who have participated in this challenge. Many of them have gone through trial and error and invested time and effort to create their own unique pop up card.

Sink Versus Float (Part II)

Using all the knowledge that children experimented and learned, they engaged in a challenge to make a boat that can carry 300 pennies, which was about 4 pounds weight. Some of children wanted to challenge themselves more and wanted to create a boat that can carry a double amount of weight: 600 pennies, which was about 8 pounds.


Grand Prize Winners



Sink Versus Float (Part I)

Children have been exploring many different materials and creating various structures. They showed a great interest in making boats. We decided to take on the challenge of making a boat that actually works, meaning it can float on the water.


We discussed what make things sink vs. float. Many children mentioned that objects that are heavy will sink and objects that are light will float. However, is it that simple? We had 2 sets of 10 items as indicated on the pictures below for children to think and record their hypothesis: which items will sink or float. Then we let the children experiment by having them place all the items on the water.
Through the experiment, children realized that concept of sink vs. float is not that simple.






To better understand our result, we graph the result and identified characteristics of different objects.


Sink and float has a lot to do with the relationship between what object goes into the water and how water reacts to that object. In order to understand the relationship, we explored various concepts mentioned below with the children.


What happens if 2 objects that are in equal size has different weights when they get dropped into water?


We dissected a squash to see why the elongated part sinks more than rounded part?


We also experimented how a dough of clay can sink when it is in a ball shape while it can float when it is flattened out.


Water Displacement

We shared a famous story by Aesop, The Crow And The Pitcher. Children were able to observe the water displacement as marble goes into the bottle. Max says “water is going up because the marble is taking up a space”.




We also put water into the syringe and ask children to block the opening and push down on the plunger. Armand said “I can’t push down the water”.



Surface Tension

What happens to a ball when it gets pushed into the water and let it go?
We also asked children what they feel when they move objects around in the water. When you move water using a wide black plastic piece vs. narrow plastic ruler, does it feel the same?
Ilan said “it’s harder to push down water when I push with a huge pot than tin container.”

Mystery Apple

“What are we having for snack today?”

Children are very excited about our daily snack making. Snack making is one of the activities that provides multiple sensory, bilateral hand coordination and hand dexterity. Through this experience, children explore science and math concepts like measurement, use of food ingredients as materials and the sequential step to step thought process.

Apple is a seasonal fruit that we had many chances to eat this Fall. We made various apple dips and tried a fresh vs. cooked apple. To explore the apples, we looked at 8 different types commonly found in the Brookline grocery stores and perform taste test on which apple is our favorite. This information will help us to pick which apple to buy for our snack. To test their learning of the various kinds of apple, children were asked to participate in challenge called Mystery Apple.

First, children made observation drawing of apples.



Second, children learned the name of apples and their physical characteristics.



Third, children tasted apples and picked their 3 best tasting apples. For the result, there was a tide between Red Delicious and Gala.


Forth, children solved what is the name of mystery apple based on their learning. Majority of children named the apple right. They were very excited about their result. Good job children!



More Pictures of children preparing snack:

1. Slicing cheese.


 2. Scooping caramel sauce.


3. Stuffing rice into tofu skin pockets.


4. Making chocolate pudding parfait.


What Is Game?

At the beginning of the fall semester, we explored the idea of: what is game? Many children already know one or more games to play. They mentioned that there are many different types of games like board games, card games, or games made with things you find at home or outside. Most importantly, games are fun when you play with others or on your own. Through playing games, they learn to make friends and develop a sense of community.

Games played inside:

Weiam, Vera, Louis, Max, Anna, Ellie, Illan, Hannah, Jacob, Ivan and Ryoji

Games played outside:

Chi Ling

Ivan shared “Chi Ling”, Chinese yoyo from Taiwan. Many children were fascinated by how it works and the many tricks you can do with it.

Louis, Jacob and Max

American Hop Scotch Vs. Korean Hop Scotch

Children shared hop scotch game from 2 different countries. Similar idea and yet it can add different flavor by having different rules and objectives.

 Unstructured Free Play:

Unstructured free play is an essential part of healthy children. Activities are children driven. Through their play, they demonstrate creativity, flexibility, team work, planning and decision making.

Creating a tree house: Illan, Piere, Ellie, JingMong, and Ashika got together to gather many branches on one day in October after a very windy night.

 Sorting acorns: Piere and Illan started to gather acorns to start a “war”. As Ryoji joined, it turned into a sorting and organizing activity. They estimated they have gather about 1000 acorns.

Our Egg Drop Inspired By Daredevil, Annie Edson Taylor: Queen of the Falls




At Lin Learning Center, we like to explore scientific concepts through picture books such as Barreling Over Niagara Falls by Nancy Kelly Allen. Through beautiful illustrations the book told the fantastic adventure of the Queen of the Falls, Annie Edson Taylor, who in 1901 was the first daredevil to barrel down Niagara Falls and survive. This concept really captured the class’s interest and they began asking where Niagara Falls is, how high it is, and so forth.

To further explore this event and expand the children’s knowledge of different materials from previous project, gravity, impact, and air resistance, we decided to do an egg drop. Each child had to design a container using open-ended materials to prevent their egg from cracking after dropped from a two-story building.

What made Annie Edson Taylor successful?

While reading Ms. Allen’s story, the children pointed out that they key reason for her survival was a well-planned design for her barrel. Thus the children observed that they would need to design the containers for their eggs with as much care, so each of them got to work drawing their plans while the teachers discussed their ideas with them throughout the process.

For our research, we examined four other daredevils who attempted the fall and made predictions whether or not they would be successful. These daredevils used a kayak, a tin barrel, water scooter, and an air-filled container. Many of the children agreed that the kayak and water scooter would not be good choices for the task. Sure enough those two daredevils didn’t make it. When we discussed why Paul commented that the kayak and water scooter were open verses the tin barrel and air-filled container provided better protection since they were closed.

Gravity, Impact, and Air Resistance

The class also discussed gravity, impact, and air resistance. While studying gravity, the children gathered that it’s what makes things fall, though Jonathan added that gravity is an invisible force that makes things fall. To further demonstrate, one of the teachers dropped an egg with no protection from the two-story building, letting the children witness it smash. Spencer noted that this was because the height of the building is about 100 times the egg.

The teachers presented the children with four different containers to use for protecting their eggs made of flexible plastic, hard plastic, tin, and glass. Then we decided to drop each of the containers from ceiling-height to observe the result. The majority of the children hypothesized that the glass container would shatter, but the others wouldn’t be damaged. During the experiment, the glass container broke, the tin can dented, and the two plastic containers had no evidence of damage. Paul stated that hard materials break while flexible ones don’t when dropped from a great height.

While researching resistance, the children learned that a parachute can slowly lower objects down to the ground, thus we performed an experiment where we dropped two papers of the exact same size from the same height. We dropped one paper vertically and the other horizontally. Jonathan and Felice pointed out that when the paper is dropped horizontally more air is touching the paper thus creating more resistance. Some of the children use this information to build a container with a parachute to minimize the impact of their egg.


Following pictures are children working on their parachutes. They were testing out their designs, giving feedback to one another and supporting each others success.

              Andrea closely looking at the parachute design to make sure air passes through.



Following pictures are children working on minimizing impact when the container hits the ground. Also some of children were thinking about creating a design that allows proper landing to guide where the impact should be when the container hits the ground.



Outcome Of The Egg Drop

After weeks of planning, building, and modifying containers, the teachers gave each of the nine children that participated two chances to perform the egg drop experiment. Some of the children focused on minimizing the impact using a parachute. Each child dropped their egg then we all went to the bottom to open the containers one by one. When we found an egg that survived, the children cheered and all of them were very happy with each other’s successes.


Following pictures are children getting ready and sharing their container design ready for egg drop. Children were allow to perform 2 trials for this challenge hoping that they learn from mistake and modify their design for another challenge.




Following pictures are children opening their containers to see whether their eggs have survived. Everyone were very supportive one another for their success as well as their failure.
