9 8. Jan noticed that when she put a tomato in water, it sank 8. Jan noticed that when she put a tomato in water, it sank. When she put an apple in water, it floated. Why did the tomato sink while the apple floated?The apple has more surface area than the tomato, which allowed the apple to float.The apple is more dense than the water, and the tomato is less dense than the water.The tomato is more dense than the water, and the apple is less dense than the water.The apple and the tomato have the same density, but the tomato skin absorbed water, making it sink.

She pours them all in and after a few minutes, the liquids separate into different layers. Which liquid would make up the bottom layer of the beaker?A. Milk, because it contains fat. B. Water, because it sinks into all substances C. Karo syrup, because it has the greatest density. D. Vegetable oil, because it has the least amount of mass.
12 11. Tim is helping his mom make a dessert 11. Tim is helping his mom make a dessert. Tim measures out one gram of peanuts and one gram of marshmallows. Which of these will need the largest container?The marshmallows will need a larger container because they are less dense.The peanuts will need a larger container because they are irregularly shapedThey will need the same size container because there is one gram of each.The peanuts will need a larger container because a peanut is heavier than a marshmallow.
