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?
