Egg-straordinary Science
With Our Kindergartners!
How strong is an egg? Will an egg sink or float?
Mrs. Cherney's kindergartners learned all about eggs in their latest Hands-On Science class! Working in groups, they talked about the properties of an egg, then hypothesized about an eggs strength. They learned that the curved form of the shell distributes pressure evenly, which makes them strong. With that, they tested the strength of the egg. They discovered that one egg could hold 46 kindergarten-sized books at 28 pounds!
Comparing fresh water to salt water, they discovered that an egg can float!
They learned about the inside parts of the egg and how cooking them changes the make up of the egg, from soft to hard when boiled. Did you know that if you spin an egg, you can tell if it is raw or hard-boiled? It's true! A wobbly, slow spin is the raw one. This taught them that when you spin a raw egg, the center of gravity changes causing the fluid inside the egg to create a wobbly motion.
One last experiment needed a teacher's assistance. Our kindergartners learned that an egg could magically be moved into a tight bottle without pushing it in or breaking it into pieces! Their teacher helped them create a vacuum inside the bottle by removing the available oxygen from the bottle!
