list the materials/ equipment needed to separate a mixture of flour, pebbles, salt, and water
What is screen, filter, heat
500
what is the difference between boiling and evaporation?

500
Name three ways you can tell that a solution is saturated
What is volume increase, mass or weight increase, undissolved material at bottom
500
list the steps needed to separate a mixture of salt, flour, pebbles, and water
What is 1. use screen to filter out pebbles 2. use filter to filter out flour 3. use heat from the sun to evaporate the water and you will be left with salt.
