Total questions: 12
Worksheet time: 6mins
1. What did you observe as the demonstrator attempted to pass the heated ball through the ring? Use diagram.
it fit through the ring easily
it barely fit through the ring
it did not fit through the ring
2. What did you observe as the demonstrator attempted to pass the cooled ball through the ring? Use Diagram.
it fit through the ring
it did not fit through the ring
3. As the metal was heated, what did you notice about the speed and spacing of the atoms in the metal?
the molecules moved faster and closer together
the molecules moved faster and further apart
the molecules moved slower and closer together
the molecules moved slower and further apart
4. As the metal was cooled, what did you notice about the speed and spacing of the atoms in the metal?
the molecules moved faster and closer together
the molecules moved faster and further apart
the molecules moved slower and closer together
the molecules moved slower and further apart
5. What do the motion lines and spacing tell you about the difference in the atoms in the metal at room temperature and in the metal when heated?
A solid has _______________ . (Pick 3)
A lot of space between particles
Very little space between particles
Particles with no definite pattern.
Particles that hold a very definite pattern.
Particles that only vibrate in place.
6. You saw an animation comparing the particles in a solid and liquid. One similarity is that in both cases, the particles are moving. (Remember: Vibrating counts as motion!) What was one of the big differences?
7. You have two substances at the same temperature. One is a solid and one is a liquid at that temperature. Do you think the attractions between particles in the solid are weaker or stronger than the attractions between particles in the liquid?
attractions between particles in a solid are weaker
attractions between particles in a solid are the same
attractions between particles in a solid are stronger
You have two substances at the same temperature. One is a solid and one is a liquid at that temperature. A student makes the claim that: The attractions between particles in the solid are stronger than the attractions between particles in the liquid? Justify this claim with a scientific reason.
9. This picture shows the flexible connection in the road on a bridge. The road on a bridge gets colder in winter and hotter in summer than the road on either end of the bridge. This is because the bridge is completely surrounded by cold air in the winter and by hot air in the summer. It is not insulated by the ground beneath it. Make a claim about the usefulness of flexible connections in the road on a bridge as seen in the diagram above.
10. A student notices on a hot day, a screen door got stuck when he/she tried to open it and that it did not fit perfectly when he/she tried to close it. And the day before when it was cold he/ she were able to open and close it without any problems.
The student made a claim that on a hot day the door expanded due to the heat and that is why he or she could not open the door right. What evidence supports his/her claim.
11. A student notices on a hot day, a screen door got stuck when he/she tried to open it and that it did not fit perfectly when he/she tried to close it. And the day before when it was cold he/ she were able to open and close it without any problems.
The student made a claim that on a hot day the door expanded due to the heat and that is why he or she could not open the door right. Justify the students claim using a scientific reason she or he is correct. Hint: In your explanation speak about the attraction and motion of molecules in a solid and how they might change due to temperature.
