##### Description:

Learning Targets

• I know what density is and can tell when something is more dense than something else.
• I can calculate density. (Density = mass x volume = m/V)
• I can explain why solid water (ice) floats.

## PhET Density Simulation

Using the above handout, complete this discovery activity.

## Notes: Understanding Density

Review the following presentation on density. Take any necessary notes in your science journal along with any questions you would like to discuss in class. Feel free to download the file in order to customize your notes.

## Eureka - Density and volume

An animated, somewhat entertaining description of volume and density.

## Checkpoint - Can I Calculate Density?

OPTIONAL - Complete the following document for practice when using the density formula given the measurements. Make sure to check your accuracy with the answer key posted in the back of the classroom.

## Bill Nye: Eggs-speriment

The oceans have always been salty, although most lakes and ponds are not salty. Do things float the same way in a lake or on the ocean?

This Sophia tutorial from Bill Nye explains that the density of salt water makes it easier for objects and creatures to float in it using a simple experiment with eggs.

Complete the activity at home and record your observations and results in your science journal. Be sure to clean up after yourself!!
