Before an investigation, four students made predictions about which balls would float and which balls would sink. The students’ predictions are listed below.Pablo predicted that balls 1 and 2 would float and that ball 3 would sink.Robert predicted that balls 2 and 3 would float and that ball 1 would sink.Christina predicted that balls 1 and 3 would float and that ball 2 would sink. Kelsey predicted that balls 1 and 2 would sink and that ball 3 would float.Look at the image to see the results of their investigation.

Which students prediction was correct?

• Pablo

• Robert

• Christina

A student measured out a volume of water in a beaker. The student’s lab partner added water to the beaker. The results are shown in the illustration. What volume of water, in milliliters, was added by the student’s lab partner? Record your answer in the grid.

Students recorded data on the diameter and mass of three spheres. Next, they placed three spheres in an aquarium full of water. The results are shown here. The data indicates that the sphere which floated had –

• the greatest mass of the three spheres

• a diameter less than 12 centimeters

• a mass between the masses of the other spheres

• the smallest diameter of all the spheres
