<p> Ocean Surface Currents Lab Directions</p><p>1. Use one of the 2-liter bottles to fill your blue pan 2/3rds full of water. </p><p>2. Using the SMALL BEAKER, combine 150 mL of slightly warm water, 1 small container of salt and 12 droppers full of food coloring. Stir this mixture thoroughly but carefully.</p><p>3. WAIT for the water in the tray to become still.</p><p>4. CAREFULLY pour this mixture into the pan with cold water from the corner. You should do this like it was demonstrated or else the lab will fail. </p><p>4. I really mean number four. Seriously!!!</p><p>5. Observe and think about how this mixture moves. This mixture is denser due to the salt. It shows deeper water currents and how currents change due to density.</p><p>6. Diagram the layers that you see in the observation section in view 1 “Before the Wind Blows”, and then ask Ms. Alsept for the blue food coloring.</p><p>7. Use the straw to gently blow on the surface of the water in order to model surface currents.</p><p>8. Draw the paths that the blue water takes in view 2 “After the Wind Blows”. This represents surface currents.</p><p>9. Clean up by pouring out your water, washing and drying your pan and beaker, throwing away your straw, and filling up your bottle again.</p>
