Today we learned that salt water has greater density than fresh water. When we did this experiment we wanted to try and find out why people float in the Red Sea. After the experiment we concluded that the Red Sea has the most salt of any body of water. This means you float all of the time.
The warmer the water is than the faster the salt dissolves.
In these pictures you can see that the colored water is separated
because the orange part has more salt then the green and the orange colored water sinks to the bottom
because it has a greater amont of salt which makes greater density than the green colored water.
Here is a short clip of the girls at work.
