Eyes Closed Questions
100
What is the relationship between heat and molecular motion?
More motion = more heat
100
What is molecular motion?
Heat
100
View the graph. What is the x-axis label? What is the y-axis label?
X-axis: Date; Y-axis: Wind speed (mi/hr)
100
If a gram of water and a gram of sand are in the same amount of sunlight for the same amount of time, do they absorb equal or different amounts of solar energy?
Equal
100
What is Ms. Motola's birthday?
December 7
200
What is conduction?
Energy transfer that happens between molecules or atoms when they come in contact
200
____________ travels through the vacuum of space, and some wavelengths travel through air. This is energy transfer at a distance without direct contact between the energy source and receiver
Radiant energy

View graph 2: What can be improved?
The y-axis is increasing by too large a unit. The y-axis should only go up to 15 or 20 mi/hr.
200
If a gram of water and a gram of soil are in the same amount of sunlight which will have a higher temperature?
Soil

Who in 6M has the first birthday of the school year?
Junho

What is the main kind of energy from the sun that heats the earth? (transfers into heat energy)
Visible light
300
Ultraviolet, infrared, microwave, x-ray, and radio are all examples of what?
Radiation

Why do we say "there is no cold, only heat"?
What we perceive as cold is actually low levels of heat. When you hold an ice cube it feels cold because heat energy is leaving your hand.
300
How many steps are there in the scientific method?
7
400
What accounts of the fact that different materials heat up at different rates? (Leads to the difference in temperature of water and soil after they have both been in the sun)
Differential heating
400
When hot matter _________ energy, the matter cools down
reradiates

View graph 4. What is missing?
Units on x and y axes
400
Which earth material can store the most heat?
Water
400
What animal is on the calendar behind Ms. Motola's desk this month?
Cat
500
Define reradiation
One way that heat energy enters the atmosphere. Hot matter radiates energy as infrared radiation which is absorbed by molecules in the air
500
What does it mean to conduct heat? Do all materials conduct heat in the same way?
To allow heat to transfer through a material. Some materials are better conductors than others - such as steel vs. aluminum
500
Please take a small white board. Graph the given information.
see board
500
What happens when radiant energy strikes an atom or molecule?
The molecule absorbs the energy and begins moving, creating heat energy. That molecule will then conduct heat to whatever material it is in contact with. It will also reradiate energy, which will be absorbed by other molecules.

How many class rules do we have?
Six
