Experimental Setup:

♠ Place a drop of blue food color at one side

♥ Place a drop of red food color at opposite side

♣ Drops will first sink and then mix with water

♦ Mixed drops will then show motion in water

♠ Look for area where water is rising

♥ Place a drop of green food color in rising water

♣ Watch what happens!

Experimental Observations

♠ Where does water appear to rise or sink?

♥ Where does water spread out (diverge)?

♣ Where does water move together (converge)?

♦ How do your observations compare with your expectations (based upon physical principles presented in the powerpoint)?

♠ How are the 2 experiments different or similar?

♥ How do the experiments compare to sea breeze, etc?
