Egg Experiment: Understanding Osmosis and Acids

In this video, Squeaks and the host conduct an experiment with an egg, vinegar, and corn syrup. They first place an egg in vinegar, which dissolves the shell due to the acid, leaving a larger egg with just a membrane. Then, they place the egg in corn syrup, causing it to shrink as water moves out of the egg. The experiment demonstrates osmosis and the effects of acids on eggshells. The video concludes with a thank you to Google Making Science and an invitation for viewers to share their experiments.

What materials are needed for the egg experiment?

• An egg, milk, a plate, and a fork

• An egg, water, a spoon, and a bowl

• An egg, soda, a brush, and a cup

• An egg, vinegar, two cups, and corn syrup

How long should the egg sit in vinegar?

• Three days

• Two days

• Four days

• One day

What happens to the eggshell when placed in vinegar?

• It disappears

• It cracks

• It changes color

• It becomes harder

What is the role of acid in the vinegar during the experiment?

• It makes the egg float

• It colors the eggshell

• It dissolves the eggshell

• It strengthens the eggshell

Why does the egg appear larger after being in vinegar?

• The egg absorbed sugar

• The egg absorbed water

• The egg absorbed salt

• The egg absorbed air

What is the main characteristic of corn syrup used in the experiment?

• It is salty

• It is acidic

• It is thick and sugary

• It is very watery

What happens to the egg when placed in corn syrup?

• It shrinks

• It becomes harder

• It changes color

• It grows larger

Why does the egg shrink in corn syrup?

• Salt moves from the corn syrup to the egg

• Air moves from the egg to the corn syrup

• Sugar moves from the corn syrup to the egg

• Water moves from the egg to the corn syrup

What is the final result of the experiment with vinegar and corn syrup?

• The egg becomes an alien egg

• The egg becomes a floating egg

• The egg becomes a solid rock

• The egg becomes a rainbow egg
