Layers of the Ocean Lab Salt water added to fresh water Observations Red Salt water added: ___________________ 2. Yellow Food Coloring added Drawing Observations Blue Ice water added: ______________________ 2. Yellow Food Coloring added _________________________ ________________________ Ice Water added to Warm Water Drawing

Instructions For Salt Water/Fresh Water Read and follow, thanx) Fill one plastic tub ¾ full of water Add water to the salt in the flask up to the 100 ml line Color the flask water red with 3-4 drops of red food coloring Stir until you can’t see any more salt in the flask Poor SLOWLY into the tub… do a little bit at a time so you don’t mix the two liquids too much/too fast Fill in the observations and draw Add 2 drops of another food coloring to top of tub, do not mix just observe and draw Use you knowledge of salinity to make as many layers as possible

Instructions for Cold/Warm Water Instructions: Read and follow, thanx) Fill one plastic tub half full of water, Ask Mason to go into back room and microwave for 75 seconds Fill one beaker ¼ full of ice cold water from Mason Color the beaker water blue with 2-3 drops of blue food coloring 4. Pour Beaker slowly and carefully into the tub… do a little bit at a time so you don’t mix the two liquids too much 5. Fill in the observations and draw Add 2 drops to top of tub at two opposite corners, do not mix just observe and draw

Conclusion Questions (Salt water added) Describe what happened when you added the salt water Why did this happen? When you added the yellow food coloring, what did you see? Does salt make water heavier or lighter? What is another name for the heaviness of an object? Why didn’t the layers mix? Conclusion Questions (Ice water added) Describe what happened when you added the cold water Why did this happen? When you added the yellow food coloring, what did you see? Does extra salt make water heavier or lighter? What is another name for the heaviness of an object? Why didn’t the layers mix?
