(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.

make me as a brainy list then I will tell   really i will

Explanation:

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
