Eggs and Earth's Wobble Demonstration

Mrs. Freeland demonstrates the concept of Earth's rotation and wobble using a boiled and a raw egg. The boiled egg spins smoothly due to its solid interior, while the raw egg wobbles because of its liquid and semi-solid interior. This illustrates how the Earth, with its liquid and semi-solid layers, also wobbles slightly on its axis over several years.

What materials are required for the science demonstration?

• Two raw eggs

• Two boiled eggs

• A boiled egg and a raw egg

• A boiled egg and a glass of water

Why does the boiled egg spin smoothly?

• Because it is lighter

• Because it is solid inside

• Because it is liquid inside

• Because it is heavier

What causes the raw egg to wobble when spun?

• Its solid interior

• Its liquid and semi-solid interior

• Its weight

• Its shape

How does the Earth's interior affect its rotation?

• It makes the Earth spin faster

• It causes the Earth to wobble slightly

• It stops the Earth from spinning

• It makes the Earth spin in the opposite direction

What is the main similarity between the raw egg and the Earth?

• Both have a liquid and semi-solid interior

• Both are solid inside

• Both are completely liquid

• Both are hollow

What is the purpose of the science demonstration?

• To show how eggs can be cooked

• To demonstrate the Earth's wobble

• To compare the weight of eggs

• To show how to spin an egg

How long does it take to notice the Earth's wobble?

• Several months

• Several years

• A few days

• A few hours
