A small hollow metal ball and a large hollow metal ball both float when placed in water. What does this tell us about their densities as compared to the density of water? 


  1. The small hollow metal ball is denser than water. 

  2. The large hollow metal ball is denser than water. 

  3. It’s impossible to determine their densities compared to water. 

  4. Since both balls float, they are both less dense than water.

Students followed the steps of the following investigation while exploring heat energy. The data they collected is recorded in the table. STEPS:

1) Fill two aluminum pans with the same amount of water.

2) Measure and record the temperature of the water in both pans using a thermometer.

3) Place one of the pans in the sun and the other in the shade.

4) After one hour, measure and record the final temperature of the water in each pan.

5) Compare the temperatures of the water in the two pans.

After comparing the temperatures of the water in the two pans, what did the students most likely infer about heat energy from the Sun? DATA:


A. Objects will absorb the same amount of heat energy from the Sun whether placed in direct sunlight or in the shade.

B. Objects placed in the shade will absorb more heat energy from the Sun than objects placed in direct sunlight.

C. Objects placed in direct sunlight will absorb more heat energy from the Sun than objects placed in the shade.

Students conducted an investigation where they tested different objects to see if they would sink or float when placed in a tub of water. The students first predicted what they thought would happen when each object was placed in the water. Then they tested each object and recorded what happened in the table. Based on what students predicted and what they observed, what must the students conclude?


A. Objects such as the rock that weigh more will sink in water, while objects that weigh less will float.

B. Solid objects with no holes will sink in water, but solid objects with holes will float.

C. The size of an object does not determine whether it will sink or float when put in water.

D. Round objects sink when placed in water, but objects that are flat will float.

The size of an object does not determine whether it will sink or float when put in water.
