Juice Lab

Introduction:  Water can come in gas, liquid or solid form.   What happens when you pour cranberry juice on top of room temperature water, ice water and boiling water?  When the juice is added to the water the juice will either diffuse with the water quickly or will mix slowly over time.

Hypothesis: When the cranberry juice is mixed with the room temperature water the juice will be mix almost completely leaving the bottom clear.  When the juice is poured in the ice water the juice will remain on the top portion of the cup and remain clear for the majority of the glass. When the juice is mixed with the boiling water the juice will immediately blend with all the water.

Procedure: First place 3 clear, similar cups on a flat surface.  Next pour 2 cups of room temperature water in cup 1. Pour 2 cups of ice water in cup 2. Pour 2 cups of boiling water in cup 3. Then divide the ½ cup of juice into 3 equal parts.  One at a time, slowly pour 1 equal part of juice into each of the three different cups filled with different temperatures of water.  As you add the juice record your observations and compare what happens in the three different cups.   
Results:

Boiling Water, Ice Water and Room Temperature Water

Juice Slowly added to the Boiling Water

Juice Slowly Added to the Ice Water

Juice Slowly Added to the Room Temperature Water

Conclusion:   When the water was poured in the room temperature cup the juice went straight to the bottom leaving the top 1/2 “ clear.  In the cup of ice water the juice went straight to the bottom and left the top ¾” of the glass clear. When the juice was added to the cup of boiling water the juice immediately dispersed throughout the cup.
