Tell kids about science with eggs at home? 8 easy and understandable little experiments to explore

Parents and mothers, please do not stay on road to accompany your children. Take some time, family is happy, and follow HandyKid to play whimsical science with most common eggs. Through these parent-child activities, you can build a closer relationship with your children.

HandyKid showed 8 small experiments with common household materials for everyone, even without food coloring (HandyKid fans should know how rare this is). The article has diagrams, materials, steps and simple explanations of principles, please collect and save them!

At top it says Precautions. Raw eggs may contain pathogenic Salmonella or parasites. After children have played with raw eggs, they should wash their hands thoroughly to prevent infection.

HandyKid Egg Science - raw eggs with Q-bombs Tell kids about science with eggs at home? 8 easy and understandable little experiments to explore

Materials: raw eggs, white vinegar, cup

Steps: put eggs in a cup, pour over white vinegar, let stand 2-3 days, remove and rinse. The egg turns into a translucent elastic egg.

Principle: The main component of eggshell is calcium carbonate. Calcium carbonate and acetic acid react chemically to form soluble calcium acetate and a gas (carbon dioxide).

Materials: raw eggs, water, paper straws, plates, cups

Stages. Fill a cup with water and cover cup with a plate. Then place paper tube vertically on plate, and place eggs on paper tube. Hit plate so that egg falls straight into cup.

Principle: when tray is quickly thrown away, eggs remain motionless due to inertia. Due to loss of vertical support, egg falls into cup under force of gravity.

HandyKid Egg Science - eggs with bare hands Tell kids about science with eggs at home? 8 easy and understandable little experiments to explore

Materials: raw eggs, plastic bags (dirt protection)

Steps: take egg in your hand, hold it firmly and crush it with all your might. Find right way?

Principle: The curved surface of eggshell can distribute pressure. When you hold whole palm, pressure is distributed over different parts of eggshell. But with uneven pressure, eggs are prone to cracking.

Materials: raw eggs, needles, white vinegar

Stages. Gently poke a small hole at both ends of egg to blow out egg liquid. Place empty shells in vinegar and they will dissolve completely after a few days. Wash and dry egg shell and it will become a regenerated "egg" when it bulges out.

Principle: The acetic acid in vinegar can react with calcium carbonate in eggshell to form carbon dioxide and calcium acetate solution, i.e. eggshell is dissolved by acetic acid. Since egg liquid has been purified, only the egg skin remains.

Materials: eggs, salt

Stages. Sprinkle a small amount of salt on table, place eggs on salt, adjust angle and stand firmly, and blow off excess salt.

Principle: The salt grains will rub against egg, and at same time salt grains will form a stable triangular support with top of spherical surface of egg, so salt grains can support egg.

HandyKid Egg Science - does it float or sink? Tell kids about science with eggs at home? 8 easy and understandable little experiments to explore

Materials: eggs, water, salt

Actions. Take a glass of tap water and a glass of salt water. The eggs will sink to bottom in first cup and float to top in second cup. If it doesn't float in second cup... add more salt to cup.

Principle: The density of raw eggs is higher than that of ordinary tap water. When salt is added to water, density increases. When density of salt water is greater than density of eggs, eggs will float.

Material: egg cartons

Stages. Arrange eggs in box with round or pointy ends up, remove your socks and step on a few eggs.

How it works. The curved surface of eggshell helps distribute pressure evenly across shell, so hen can sit on and incubate egg without breaking it.

HandyKid Egg Science - eggs swallowed in a bottle Tell kids about science with eggs at home? 8 easy and understandable little experiments to explore

Materials: boiled eggs, glass bottles, matches

Steps: Find a heat-resistant glass bottle that has a neck that is slightly smaller than size of an egg, and it is difficult to stuff egg completely into bottle with bare hands. After boiled eggs are peeled, throw a burning match into bottle and quickly place eggs on neck of bottle. After fire in bottle is extinguished, eggs are pushed into bottle by an invisible force.

Principle: A match in a bottle burns, causing gas to expand when heated, and part of gas flows out of neck of bottle. After match goes out, air in bottle gradually cools, gas is compressed, and air pressure becomes less than atmospheric pressure, forming a pressure difference with outside of bottle. External atmospheric pressure "squeezes" egg into bottle.
