The Hardest Part
Author: Doyoon Yoo
Chicks seem to know when it is time to hatch. After about 19 to 21 days, they are fully developed, have absorbed most of the nutrient-rich yolk, and are running out of space inside the egg. They first break into the air pocket at the larger end of the egg and begin breathing. Then, they use a small, sharp egg tooth on their beak to start pipping, or breaking through the shell.
I think getting out of the egg is the hardest part. The tiny chicks must use almost all their strength to push and crack the shell. That is why hatching can take several hours. Chicks often stop to rest before they continue pushing.
The cracks in the shell do not always form an exact shape. Sometimes, a chick makes cracks around the shell in a circle, but other times, it may only make one small hole and stay there for an hour or longer. Every chick hatches in a slightly different way.
Fun Fact!
Did you know that female chickens can lay eggs without a male chicken? However, those eggs are not fertilized, so chicks cannot develop inside them.

Origami
Author: Doyoon Yoo
Origami is a traditional Japanese art form made by folding paper — popular examples include paper planes, jumping frogs, and paper boats. Paper boats float thanks to buoyancy, and the air trapped inside their folded structure helps hold them together. Left in water, a typical paper boat will usually survive for only about 1–3 minutes before the paper becomes soggy and sinks.
The largest folded paper boat ever recorded measures 45 ft 8.4 in long, 13 ft 9.3 in wide, and 13 ft 7.3 in tall. It was created by Frank Bodin and the Daxlandiade Volunteers in Karlsruhe, Germany, in 2015 — built to celebrate the town's 300th anniversary.
Here's how to make your own paper boat.
The Physics of Buoyancy
Fb=ρVgF_b = \rho V gFb=ρVg
-
ρ (rho) — the density of water
-
V — the volume of the submerged part of the boat
-
g — the acceleration due to gravity
Buoyancy is the upward force water exerts on any object placed in it. If that upward push is equal to or greater than the weight of the boat, the boat floats.
Interestingly, no one knows exactly who invented the paper boat — its exact origin remains a mystery to this day.
💭 Think About It!
China is credited with inventing paper, but Japan is credited with inventing origami. Doesn't it seem like China should have been the one to invent paper folding first? What do you think? Share this question with your friends and family, and see what they say!
Quiz Time! 🧠
1. What is buoyancy? Write the equation.
2. What does V represent in the buoyancy equation?
3. Where did origami come from?
Hope you got them all correct!

What is Augmented Reality(AR) ART ?
Augmented reality (AR) art is a new type of art that enables real-time interaction between the real world and the virtual world by seamlessly converging the three-dimensional virtual world into the real world in real time. It is a technology that provides users with an improved sense of immersion and reality.

A membrane made of gel forms around rock. Then, since there is more water outside than inside the membrane, and so osmosis occurs. Water moves inside of the rock. Becuase there is so much water inside the membrane after a while, the membrane breaks. Then, since the ions are less dense than the water outside, it rises up. The Sodium Silicate in the solution reacts with the rock ions, which causes the solid to form. This is called precipitation.

What is the science behind slime? By Rachel L, 13
We made slime today, but I wanted to know the science behind it.
Glue has something called polyvinyl alcohol, aka PVA. PVA is also found in peel off face masks, and you can make slime with them instead of glue.
Slime is basically polymers, that is molecules made by linking together chains of smaller parts.
Borax dissolved in water has borate ions, which forms Hydrogen bonds with the OH groups in the PVA in the glue. This forms the polymer: slime.
Adding more borax makes the slime harder, and this is because more links are made, and so the polymer is stiffer.
We made slime with different amounts of borax solution, and the more borax solution, the harder the slime was. That is the science behind slime.

Elephant Toothpaste
Experiment Analysis

Elephant toothpaste is given its name because of the giant foam that appears after mixing a few ingredients together! When hydrogen peroxide comes into contact with yeast, it is broken down into water and oxcygen. The oxygen wants to escape, and turns the mixture into large foam.
Kids Do Finance
STAX is a comprehensive educational game designed to provide students with a hands-on experience in the world of investing. The simulator spans a simulated time frame of 20 years, allowing participants to engage in virtual investment activities across various asset classes such as stocks, commodities, bonds, and more. STAX aims to impart practical knowledge and understanding of financial markets, risk management, and investment strategies in a controlled and risk-free environment.

Self Hygiene Guardians- Glo Germ Experiment
It's crazy to think that only 5% of the people in the entire world wash their hands with the correct steps even though hands are the most common way to spread germs! With this experiment, kids are able to see "germs" under UV light and understand the importance of hand washing and hygiene.

Solar Powered Mini Race
By Hosannah Choi
During the NorthWest Innolab Summer Camp, the kids used solar powered miniature cars to race each other! Not only was this a valuable lesson towards future sustainability, but also a fun competition. Solar panels work by absorbing energy from the sun which creates an electrical charge and allows electricity to flow.
The race featured a racing track created from recycled wood and designed by the kids and staff/volunteers! Our main theme for this was the importance of our Earth and environment and how we should be working to save it
