Separating Materials in Mixtures

What is the primary factor that helps in determining the best way to separate materials in a mixture?

• Physical properties of the materials

• Color of the materials

• Size of the materials

• Shape of the materials

In the given example, what are the two types of materials present in the jar?

• Glass marbles and metal cubes

• Plastic cubes and wooden marbles

• Glass marbles and plastic cubes

• Metal marbles and plastic cubes

Why do plastic cubes float when water is added to the jar?

• They are the same density as water

• They are less dense than water

• They are more dense than water

• They are heavier than water

What happens to the glass marbles when water is added to the jar?

• They change color

• They remain at the bottom

• They dissolve in water

• They float to the top

What is the final step in separating the plastic cubes from the glass marbles?

• Pouring out the water

• Shaking the jar again

• Scoop the cubes out

• Adding more water
