Calculating Density Using Volume Displacement With Spongebob

The video tutorial explains how to find the density of an object using volume displacement. It uses Spongebob as an example, showing how to measure his volume by observing the change in water level in a graduated cylinder. The tutorial then demonstrates how to calculate density by dividing Spongebob's mass by his volume, concluding that his density is 25 grams per milliliter. The lesson wraps up with an invitation for questions.

What is the principle behind volume displacement?

• Calculating the time taken for an object to sink

• Measuring how much the water level rises

• Measuring the weight of an object in water

• Observing the color change in water

In the example with Spongebob, what was the initial volume of water in the graduated cylinder?

• 50 milliliters

• 54 milliliters

• 52 milliliters

• 48 milliliters

How much did the water level rise after Spongebob was added to the graduated cylinder?

• 4 milliliters

• 2 milliliters

• 3 milliliters

• 1 milliliter

What is the mass of Spongebob as measured on the electronic balance?

• 75 grams

• 50 grams

• 100 grams

• 25 grams

How is density calculated?

• Volume minus mass

• Mass multiplied by volume

• Mass divided by volume

• Volume divided by mass

What is the density of Spongebob based on the given measurements?

• 25 grams per milliliter

• 30 grams per milliliter

• 15 grams per milliliter

• 20 grams per milliliter

What should you do if you have questions about the density investigation?

• Ask the teacher in class

• Search online for answers

• Guess the answers

• Ignore the questions
