Sam built a rocket using a full set of blocks. How would taking the rocket apart effect the total mass of the blocks?

• The total mass of the blocks would double.

• The total mass of the blocks would be the same apart as together.

• The total mass of the blocks would decrease because they are together.

• The total mass of the blocks would increase because the blocks are apart.

Ms. Williams tore a sheet of paper into pieces. How does the mass of all the pieces compare to the mass of the sheet before it was torn?

• The total mass of the pieces would be greater than the mass of the whole sheet.

• The total mass of the pieces would be greater than the mass of the whole sheet.

• The total mass of the pieces would be more than twice the mass of the whole sheet.

• The total mass of the pieces would be the same as the mass of the whole sheet.

John, Jacob, and Jamian were creating figures with modeling clay. They divided a 90-gram bar of clay. John and Jamian combined their clay to make one large figure, then Jacob added his. What happened to the mass of the figure they created?

• The resulting figure’s mass would be about 180 grams, since John and Jamian’s figure had twice as much clay.

• The resulting figure’s mass would be about 90 grams, since the divided clay was formed back together.

• The resulting figure’s mass would be about 30 grams, since the original bar was divided into thirds.

• The resulting figure’s mass would be about 270 grams, since all three boys combined their clay.

Jack can split logs without any chips falling from them. He cuts a tree stump into four logs. He then splits each log into two smaller pieces, making a total of eight pieces of wood. Which best explains the mass of the eight pieces of split wood?

• The split wood’s mass is less than the mass of the original stump.

• The split wood’s mass is the same as the mass of the original stump.

• The split wood’s mass is more than the mass of the stump because there are more pieces.

• The mass of the four logs is the same as the original tree stump, but the final mass of the eight pieces is less than the original tree stump.
