1. Use colored markers or crayons on the illustration below to mark your prediction about the

movement of the colored, salty water in the bottles, and where it will end up. Label which bottle

has the fresh water and which bottle has the salty water at the start of the exploration.

This is where the colored,

salty water starts in the bottles.

This is where I predict the

colored, salty water will end up.

2. Now color in what actually happened

This is where the colored,

salty water started in the bottles.

This is where the colored, salty water

ended up in the bottles.

or why not? Be Specific.
