Riley makes three balls out of modeling clay.  He puts all the balls on a balance.  The total mass is 56 grams. He then pushes the clay into one big ball and measures its mass.  Which of the following would be a reasonable mass for the entire ball?

• 50g

• 53g

• 55g

• 56g

Peter places six balls of modeling clay on one side of a balance.  He places a plastic cup on the other side.  It takes 41 plastic cubes to balance the modeling clay. He then removes the clay, shapes it into a dinosaur, and puts it back on the balance. 

How many cubes will he MOST LIKELY need in the cup to balance the dinosaur?

• 31 cubes

• 38 cubes

• 41 cubes

• 47 cubes

During an experiment, a student measures the mass of ice and of liquid water, then places the mixture in the freezer for a day.  The table shows the data:

Mass of Ice Mass of Liquid Water Mass After the Change:

50 grams 75 grams ??????

What will the student most likely have at the end of the experiment?

• 100 grams of ice

• 125 grams of ice

• 125 grams of liquid water

• 150 grams of liquid water

Joshua has a bag of identical blocks.  He makes a toy building using 15 of the blocks and puts it on the left side of a balance.  He puts a handful of blocks on the right side of the balance.  The right side sinks down.  Why does this most likely happen?

• Joshua has more blocks on the left side.

• Joshua has more blocks on the right side.

• Both sides have the same number of blocks but combining slightly adds to the mass.

• Both sides have the same number of blocks but combining slightly decreases the mass.

When on Mars, your mass and weight would be the same because gravity has no impact on weight.

• true

• false

• weight and mass are the same

• weight is measured in grams, mass in ounces

Petra has a container of water.  Based on what she knows about particles in matter, she draws a model of the water particles before her investigation and after her investigation.  Petra's model originally has particles tightly packed together, but then the particles begin moving faster and appear to be a gas after her investigation.  

• Petra heated the water, and it turned to ice.

• Petra heated the water, and it turned to ice.

• Petra cooled the water, and the particles moved faster.

• Petra heated the water, and the particles moved faster.

A group of students carry out an investigation.  They observe and measure different properties of matter.  Their data for four samples of matter are shown in the table.

Properties of Matter:

Sample Texture Texture Soluble

W soft & silky white no

X grainy tan no

Y rough granules white yes

Z soft & silky pink no

WHICH SAMPLE IS MOST LIKELY SALT?

• W

• X

• Y

• Z
