Size? Density? Movement? Process? Increases Decreases Rises Up Convection

1: Flame heats bowl (by radiation) 2: Bowl heats water (by conduction)

Q1: What will happen to hot blob of water? Size? Density? Movement? Increase Decrease Rise upward (Convection)

Q2: How does pressure change above/below? At top? At bottom? Increases Decreases H L

Q3: How will water move at top and bottom? At top? At sides? At bottom? Spread out (Diverge) Sinking Move Inward (Converge) H L

Experimental Instructions ♠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?
