Use The Scientific Process To Solve The Mystery Of The Mysterious Milk

Follow these steps when performing an experiment:

I. State the Problem:

II. Research

If needed, use a separate sheet of paper for greater detail.

 

 

III. Hypothesis

IV. Step by Step Procedure

Materials:
petri dish
room temperature whole milk
4 colors of food coloring
liquid dish soap
dropper
beaker

Procedure:
1. Use the beaker to carry the whole milk to the laboratory area.
2. Fill the petri dish 1/2 full of milk. Do not disturb the milk during this experiment.
3. Very carefully put 2 drops of each color of food coloring on opposite areas of the petri dish. see diagram.
4. Put 2 drops of liquid dish soap into the center of the petri dish of milk. Make sure that the dropper does not touch the milk.
5. Observe the petri dish for 1-3 minutes.
6. Write down what was observed.

Observations:

 

 

Conclusion:

What were the variables in the experiment?

 

Refer back to the hypothesis.

 

What happened?

 

If you could change one thing (variable) and do the experiment again, what would you change?
