Think about particle size and answer this question: Why did the salt go through the filter while the sand got caught?||The dissolved salt particles are small enough to go through the holes in the filter paper, but the sand particles are too large.||Because he put water in it so the salt dissolved with the water and ran right through. | partially_correct_incomplete |
Gerry used a paper filter to separate a mixture of sand, salt, and water. Think about particle size and answer this question: Why did the salt go through the filter while the sand got caught?||The dissolved salt particles are small enough to go through the holes in the filter paper, but the sand particles are too large.||Because salt is so small it slid through the large coffee filter. Sand is larger so it stuck to the filter. | correct |

Think about particle size and answer this question: Why did the salt go through the filter while the sand got caught?||The dissolved salt particles are small enough to go through the holes in the filter paper, but the sand particles are too large.||The salt turns to liquid like an ice cube and then to water sand does not. | partially_correct_incomplete |

Think about particle size and answer this question: Why did the salt go through the filter while the sand got caught?||The dissolved salt particles are small enough to go through the holes in the filter paper, but the sand particles are too large.||The sand was too big to fit through the tiny holes in the filter. The salt dissolved into the water and was way too small to get caught in the filter. It just went through. | partially_correct_incomplete |
