This scientific inquiry requires you to investigate
the concepts of suspensions and solutions. You are to perform the
experiment and observe your results.
Experiment: Label four plastic cups as follows: salt, cooking oil, pepper,
sugar. Fill each cup one-half full of water.
Predict what will happen when each of the 4 ingredients is added to the
appropriately labeled cup. Add 1 teaspoon of each ingredient to the
properly labeled cup and stir. Observe and record what happens in each cup.
Place a paper towel over an empty cup and pour a small portion of the
"salt" cup through the towel. Repeat this step using the
remaining cups.
Observe and record your observations. Make a conclusion based on your
observations. In your science journal write a complete, but concise, report
of your experiment. Include your prediction and conclusions, how they
compare, and what you learned from the experiment.
