(WILL MARK BRAINLIEST) Ms. Baker’s science class completed their science investigation on separating a mixture of salt, sand, and iron filings. Students used the tools below to separate their mixture and observed their outcome. Sam noticed that salt was not visible and predicted it was in the cup of water. (SC.5.P.8.3)

How will Sam need to prove her prediction is correct?

A. Sam will need to increase the temperature of the water in the cup. The heat will cause the water to evaporate and leave the salt crystals behind.

B. Sam will need to freeze the salt to make it stronger so that it floats in the cup.

C. Sam will need to use the magnet to separate the salt in the cup of water.

D. Sam will need to use the hand lens to observe the water and find the salt floating in it.
