What things in the universe have matter?
All objects that take up space. A tree is made of matter, but the tree's shadow is not.
100
Which has more mass - a beach ball or a baseball?
The baseball - there is more matter in the baseball, so it has more mass.
100
What has more volume - A beach ball or a baseball?
A beach ball - the beach ball takes up more space than the baseball does, so it has more volume.
100
Which is more dense - A backpack filled with homework, or a backpack with no homework?
The backpack filled with homework. The backpack takes up the same space, but one has much more matter in it than the other. Since it has more matter in the space, it is more dense.
100
True or false - Everything that is made of matter is made of tiny particles.
True
200
The three main states of matter are ...
Solids, liquids, and gases
200
What is mass?
A measure of the amount of matter ("Stuff") in an object.
200
What is volume?
Volume is a measure of the amount of space an object takes up.
200
Which is more likely to sink in water - a very dense object or a very light object?
A very dense object

What is the name for the tiny particles that all matter is made of?
Atoms

True or False: The state of matter an element is in can be changed by temperature.
True. When solids are heated, they can melt. When liquids are heated, they can evaporate into gas. On the other hand, when gases cool, they condense into liquids. When liquids are cooled, they can freeze into solids.
300
Objects with more mass exert more ______________ force.
Gravitational

To find the volume of a box, multiply the boxes length, width, and height. What is the volume of a box with a length of 5 inches, a width of 4 inches, and a height of 5 inches?
100 in (cubed). 5X4X5 = 100.
300
If something is LESS dense than water, what will happen if you place it in a tub?
It will float; more dense matter sinks and less dense matter rises. Since the object is less dense than the water, it floats above it.
300
Do food coloring particles move more quickly in hot water or cold water?
Hot water
400
All matter has the following three properties: shape, ______, and _______.
Shape, mass, and volume.
400
What happens to the mass of an object when you cut it apart or change its shape?
The mass will stay the same. If you cut an apple into 8 slices, the 8 slices will have the same mass as the 1 whole apple.
400
True or false - the volume of a liquid is changed when you pour it from a skinny cup into a wide cup.
False - the volume of a liquid stays the same, even when the container changes.
400
True or false - two objects can have the same volume, but have different densities.
True - density measures the amount of matter in a certain space. Compare a basketball to a balloon. Both may have the same volume, taking up the same space. However, the basketball has much more matter in it. Since the basketball has more mass, it will be more dense than the balloon.
400
When atoms join together, they create _________________. (hint - water is an H20 ______)
Molecules

Describe how water is different in each of the three states of matter.
In its solid form, water is very cold and rigid (Ice). In its liquid form, water is able to move around, but it stays together. In its gaseous form, water mixes into the air and can move apart without staying together (water vapor).
500
Mass and weight are not the same thing. What does mass measure, and what does weight measure?
Mass measures the amount of matter in an object. Weight measures the force of gravity pulling on an object.
500
Which state of matter has no definite (always the same) volume?
Gases; solids take up space in their shape, liquids fill up space wherever they are, but gases can spread about far or be packed in tight. They can have a little volume or a lot of volume.
500
How are mass and volume related to density?
Density is a measure of the mass divided by the volume. You could also see it as a fraction. Density = mass/volume.
500
Describe how the particles in a gas are different from the particles in a solid
The particles in a gas are able to move around faster and can move apart. The particles in a solid stay rigid and locked together.
