Your weight on the moon is about one-sixth of your weight on Earth. Why do you weigh less on the moon?

• The moon exerts a greater gravitational force because it is more dense than Earth

• The moon exerts a smaller gravitational force because it has less mass than Earth

• The moon exerts a greater gravitational force because it is closer to Earth than the sun

• The moon exerts a smaller gravitational force because objects are closer to its center than on Earth

The picture shows a density column that Jim created by pouring four different liquids, each with a different density, into a graduated cylinder. If Jim had previously found the mass of each individual liquid and used what he observed in the column to determine each liquid's density, which table correctly shows what Jim recorded about the liquids' densities?

Vince’s mass on Earth is 79 kg and his weight on Earth is 174 pounds. If Vince was to travel to the moon, how would his mass and weight change?

• Vince’s mass would increase as well as his weight.

• Vince’s mass would decrease as well as his weight

• Vince’s mass would stay the same but his weight would increase

• Vince’s mass would stay the same but his weight would decrease

Matthew has six cubes of different materials. Each cube has a mass of 10 grams (g). Matthew sorts the cubes into two groups using one physical property. Which physical property did Matthew most likely use to sort the cubes into two groups?

• density

• magnetism

• melting point

• electrical conductivity

Listed are the densities of four different metal cubes. Each cube has a volume of 4 cm³. D=M/V. Which cube will have the greatest mass?

• Brass

• Gold

• Iron

• Lead

Your weight on Jupiter is about 2.5 times of your weight on Earth. Why do you weigh more on Jupiter?

• Jupiter exerts a greater gravitational force because it is more dense than Earth

• Jupiter exerts a smaller gravitational force because it has less mass than Earth

• Jupiter exerts a greater gravitational force because it is closer to Earth than the sun

• Jupiter exerts a smaller gravitational force because objects are closer to its center than on Earth

Ashley wants to compare the solubility of three materials: salt, sand and flour. She fills three beakers with 500 mL of water each. She then adds the same amount of each solute to the three beakers below. Based on Ashley’s observations what statement can she make about the solubility of the three materials?

• Sand is the most soluble

• Flour is the most soluble

• Salt is the most soluble

• All are equally soluble

James has three blocks with the same size. He places the blocks in water and observes them. Block A floats in the middle, blocks B sinks to the bottom and C floats to the top of the water. Which statement below can James make about the density of each of the blocks?

• Block A is less dense than block B

• Block C is more dense than block B

• Block B is more dense than block C

• Block C is more dense than block A
