Sally is doing an experiment with mixtures. She pours sugar into a glass of water and stirs it until the sugar disappears. Then, she pours oil into another glass of water, and the oil stays separate on top of the water. Which of the following statements best explains the difference between these mixtures?

• A. Sugar and water form a solution because the sugar dissolves, but oil and water do not mix because they form two separate layers.

• B. Sugar and water form a solution because the sugar floats, and oil and water do not mix because the oil sinks to the bottom.

• C. Sugar and water form a mixture with two layers, but oil and water form a solution because they combine completely.

• D. Sugar and water do not mix at all, but oil and water form a solution because the oil dissolves in the water.

Which objects could also be classified in Group 1? Select TWO correct answers.

• Feather

• Wooden spoon

• Refrigerator magnet

• Cotton shirt

• Steel nail

In a demonstration for the class, Mrs. Hamish mixes oil and water. The mixture has a mass of 80 grams. What must be true about the masses of oil and water in the mixture?

• Either the mass of oil or the mass of water must equal 80 grams.

• The sum of the masses of oil and water must be greater than 80 grams.

• The difference between the masses of oil and water must equal 80 grams.

• The sum of the masses of oil and water must equal 80 grams.
