Names
1. Title-Ocean Water Properties Lab
2. Purpose-The purpose of this experiment is to explore the physical properties of Ocean
water.
Questions:
1. What is the density of salt water?
2. What is the density of freshwater?
3. What is the difference between water of high salinity (very salty) and low salinity (not
very salty)?
4. What effect does density have on water currents?
5. What is the density of a carrot/potato?
3. Hypothesis (predictions)
-I predict that the density salt water is…
-I predict that density of freshwater is…
-I predict that the density of the potato/carrot is…
-I predict that density effects water currents…(how?)
