We finished our second experiment with Julie Wille today. We made density columns. But first we started with the trusty Scientific Process.
Question: Do all liquids weigh the same?
Materials: corn syrup, water with blue food coloring, vegetable oil, an empty bottle.
Procedure: add the three liquids together in the empty bottle. See what happens.
Hypotheses:
1. It will turn black.
2. It will turn blue.
3. It will bubble up.
4. It will make a new kind of oil.
5. The top of the bottle with fly off.
6. It will mix together.
7. It will turn dark green.

 All shook up! |  Starting to separate again! |
Results: The corn syrup was the heaviest and sunk to the bottom, the water was next and stayed in the middle, the oil was the lightest and rose to the top. When we shook them up they mixed, but then separated into two layers of really pretty blue colors. What's in each of the two layers?
