Vocab
____________________ is anything that has mass and takes up space.
Matter
This is the amount of space an object takes up
_____________ this is the state in which a substance maintains a fixed volume and shape. The particles are packed closely together.
Solid
this is a substance that contains two or more substances which are not chemically combined.
mixture
True or False: The mass of an object changes if you move it to a different location.
False – Mass does not change based on location; it is the amount of matter in an object.
______________ is the measure of the amount of matter in an object.
mass
A __________ reaction is a process in which one or more substances undergo a change to become a different substance altogether.
chemical
________ is the state in which a substance adapts to the shape of its container, and mostly maintains its volume. The particles are touching by they can move past each other.
Liquid
______ of mass is the principle that matter can neither be made nor destroyed; rather, it can only be transformed or transferred from one form to another.
conservation
You have a piece of clay. If you shape it into a ball or flatten it, what property stays the same?
a) Shape
b) Color
c) Mass
d) Texture
c) Mass – The mass of the clay remains the same no matter its shape.
________________ is matter that has specific components and properties.
substance
What is Ms. Pardee's favorite color (besides neutrals)? Be specific
Terracotta
___________ this is the state in which a substance expands to occupy the volume and shape of its container. The particles are fast moving and can spread apart from each other.
Gas
You want to make a chocolate milk drink. You add one spoonful of chocolate powder to a glass of milk and stir until the powder is completely mixed in. Did you create a new substance? Why or why not?
No, you did not create a new substance. You made a mixture because the chocolate powder and milk are combined but not chemically changed. The powder is just dispersed throughout the milk, and you could separate them again (like by letting the milk evaporate).
What happens to the volume of water when it freezes into ice?
a) It increases
b) It decreases
c) It stays the same
d) It disappears
a) It increases – When water freezes, it expands, so the volume increases as it becomes ice.
This is a characteristic of a material
Property
If Ms. Pardee could travel anywhere, where would she go?
a) Bora Bora
b) Italy
c) Greece
d) Australia
c) Greece
_____________ is a very small piece of matter. All matter is made of particles too small to be seen.
Particle
You have a cup with 200 grams (g) of sand. You add a small rock that weighs 50 g to the cup. What is the mass of the cup with the sand and rock together? Explain your answer.
a. 200 g
b. 250 g
c. 150 g
d. 300 g
The mass of the cup with the sand and rock together is 250 g. This is because you add the mass of the sand (200 g) and the mass of the rock (50 g) together:
200 g+50 g=250 g
The total mass is the sum of both parts since nothing was lost or added besides the rock.
Which property of matter describes how much space an object takes up?
a) Mass
b) Volume
c) Density
d) Weight
b) Volume – Volume measures the amount of space an object occupies.
This is the matter from which a thing can be made
Material
When is Ms. Pardee's Birthday?
August 27th
Describe the particle arrangement of a solid, liquid and gas.
Solid: particles are packed tightly together. The particles don't move but vibrate.
Liquid: particles are close together but not in a fixed pattern. They can slide past each other. That is why liquids can flow and take the shape of the container.
Gas: particles are spread far apart and move freely and quickly in all directions. They take up all the space available to them.
True or False: A mixture can be separated into its original parts.
True. A mixture can be separated into its original parts because the substances in a mixture are physically combined, not chemically bonded.
What is the property of matter that describes how tightly packed the particles are in a substance?
a) Density
b) Volume
c) Color
d) Weight
a) Density – Density refers to how tightly the particles are packed in a substance. It is calculated by dividing the mass by the volume.
