a)
physical change
b)
chemical change
c)
scientific change
d)
geological change
2.
Ava put water, sugar, and yeast into a balloon. Then she put the balloon into a pan of warm water and observed how the balloon changed. Next, Matthew repeated the investigation with another balloon. What is the best reason for Matthew to repeat it?
a)
To write the same report.
b)
To practice the experiment.
c)
To come to the same conclusion.
d)
To be sure her observations are accurate.
3.
Sam put water, sugar, and yeast into a balloon. Then he measured the mass of the balloon. He put the balloon in a warm place for 2 hours. Then he measured the mass again. He repeated his experiment three times to get more data. Predict how the mass of the balloon changed.
a)
less mass
b)
more mass
c)
same mass
d)
no more mass
4.
Tink filled two balloons with the same amounts of water, sugar, and yeast. She put one on a table in the classroom. She put the other on a sunny windowsill. Why did Tink observe that the balloon in the window was larger?
a)
The windowsill is cooler than the table.
b)
The windowsill is warmer than the table.
c)
The classroom table is warmer than the windowsill.
d)
The classroom table is the same temperature as the windowsill.
5.
There are three main states of matter: liquid, solid, and gas. Which statement describes the shape of a solid?
a)
It has its own shape.
b)
It doesn't have a shape.
c)
It takes the shape of its container.
d)
It changes shape with temperature.
6.
Which statement describes a difference between solids and liquids?
a)
Temp. can change a solid to a liquid, but it can't change a liquid to a solid.
b)
Solids have a definite volume, but liquids do not.
c)
The particles in a solid are much closer together in a solid compared to a liquid.
d)
Solids take the shape of their containers, liquids maintain their own shape.
7.
Cat and Roni want to find the volume of four different cubes. Which tools are best for measuring the volume of solids?
a)
balance and ruler
b)
graduated cylinder and ruler
c)
balance and graduated cylinder
d)
graduated cylinder and thermometer
8.
Matter may be a gas, solid, or liquid. It can change from one state to another. Which change most often causes matter to change state?
a)
change in mass
b)
change in color
c)
change in volume
d)
change in termperature
9.
Each of the states of matter has specific characteristics. Which statement correctly describes one of these characteristics?
a)
Solids flow from one place to another.
b)
Gases can expand and be compressed.
c)
Liquids have definite volume and shape.
d)
The particles in solids have weak forces of attraction
10.
When an egg is cracked and put in a hot pan, it flows easily. After it cooks for a minute, the egg becomes solid.
a)
Breaking the shell is a physical change in the egg that make it solid.
b)
Breaking the shell is a chemical change that makes the egg become solid.
c)
Heating the egg on the stove causes the egg to evaporate and become solid.
d)
Adding heat causes a chemical change in the molecules of the egg that makes it solid.
11.
Ryn tried to remove a metal lid from a glass jar but the lid was too tight. Her mother suggested that she hold the jar so that the lid was in hot water for a minute or two and then try to remove the lid. After Stacey did this, the lid turned easily. How did the hot water make the lid easier to remove?
a)
Heating the glass jar made it expand, so the lid turned easily.
b)
As the metal lid was heated, it expanded so that it was not as tight.
c)
Water on the metal lid made it easier to hold, so it was easier to turn.
d)
Water on the metal lid made it easier to hold, so it was easier to turn.
12.
A change in state that does not change the chemical composition of a substance is a physical change. Which of these conditions has the greatest effect on how quickly a substance changes from one state to another?
a)
color
b)
light
c)
shape
d)
temperature
13.
If you look closely at the rail on a railroad track, you will see small gaps between sections of metal rails. Why are these gaps needed?
a)
They allow the metal to expand when it is heated without bending the rails.
b)
They allow the metal to expand when it is cooled without bending the rails.
c)
They keep the metal rails from touching and having chemical reactions with one another.
d)
They keep the metal rails from touching one another so that chemical reactions with air happen faster.
14.
Some foods can be stored in cabinets without cooling, but others must be refrigerated. Why does milk have to be kept in a refrigerator if it is not going to be used soon?
a)
Milk tastes much better when it is cold, so people keep it refrigerated.
b)
Chemical reactions in the organisms that cause milk to spoil are slower at lower temperatures.
c)
Physical reactions in the organisms that cause milk to spoil are slower at lower temperatures.
d)
Refrigerating the milk keeps it cold enough that no chemical or physical changes take place and the milk will not spoil.
15.
Glue forms a bond between two pieces of wood as a result of a chemical change. How could you make the glue harden faster?
a)
Heat the glued joint with a hair dryer.
b)
Place the glued pieces of wood in the refrigerator.
c)
Use a clamp to hold the pieces of wood together while the glue hardens.
d)
Use more glue between the pieces of wood so that the reaction is faster.
