Egg Floatation Experiment Analysis

In this video, Teresa from Homeschool Primer conducts Experiment 3.1 from Apologia General Science, focusing on density and buoyancy. The experiment involves testing how an egg floats in tap water compared to salt water. Initially, the egg sinks in tap water. By gradually adding salt, the water becomes denser, eventually causing the egg to float. The video demonstrates the process step-by-step, highlighting the changes in buoyancy with each salt addition, and concludes with the scientific explanation of the results.

What is the main objective of the experiment conducted by Teresa?

• To find out how fast an egg can sink.

• To measure the temperature of water.

• To determine how an egg floats in different liquids.

• To observe the color change in water.

Which of the following materials is NOT required for the experiment?

• Salt

• A tall glass

• A raw egg

• A thermometer

What was observed when the egg was placed in tap water?

• The egg sank to the bottom.

• The egg floated to the top.

• The egg dissolved in water.

• The egg changed color.

What is the purpose of adding salt to the water in the experiment?

• To make the egg heavier.

• To decrease the water's temperature.

• To increase the water's density.

• To change the color of the water.

After adding the first teaspoon of salt, what was the egg's behavior in the water?

• It started to float slightly.

• It remained at the bottom.

• It floated to the top.

• It dissolved in the water.

How many times was the process of adding salt and testing the egg repeated?

• Three times

• Four times

• Five times

• Six times

What was the result after the final addition of salt?

• The egg floated to the top.

• The egg sank to the bottom.

• The egg remained in the middle.

• The egg dissolved.

What conclusion can be drawn from the experiment?

• Salt increases the density of water, allowing the egg to float.

• Salt makes the egg heavier.

• Salt has no effect on water density.

• Salt decreases the density of water.

What happens to the egg as more salt is added to the water?

• The egg sinks faster.

• The egg dissolves.

• The egg changes color.

• The egg starts to float.

Why is it important to record observations in a notebook during the experiment?

• To ensure the egg doesn't break.

• To keep track of changes and results.

• To make the water denser.

• To remember the color of the egg.
