A cup of sand is mixed into a bucket of rocks. Another cup of sand is mixed into a bucket of water. Which statement best compares the two buckets?

• Only the bucket with rocks is a solution because materials can be evaporated from the rocks.

• Both buckets are mixtures because the materials can be separated easily by physical means.

• Both buckets are solutions because the materials can be separated using a strainer.

• Only the bucket with water is a mixture because the sand is dissolved by the water.

Which statement about the data table is true?

• Magnet 3 is the weakest.

• Magnet 4 is the strongest.

• Magnets 1 and 3 are the strongest.

• Magnets 2 and 3 are the weakest.

What evidence from the data table above supports the teacher's claim that matter is conserved?

• The ice cubes melted when placed in the water.

• The total mass of the melted ice and water is the same as the ice cubes before they melted and the water.

• The mass of liquid water is greater than that of solid ice cubes.

• There is no evidence of matter being conserved.
