Which position would the Moon be in during an eclipse of the Sun?
-
A
No. In this position, the Earth would not be in the Moon's shadow. -
B
Yes! Solar eclipses only happen during a new moon, but even then, the alignment has to be just right for the Moon's shadow to fall on the Earth. -
C
No. In this position, the Earth would not be in the Moon's shadow. -
D
No. In this position, the Earth would not be in the Moon's shadow. You might get a lunar eclipse in this position, but not a solar eclipse.

This is called Marble. It was once limestone, but heat and pressure changed it, recrystallizing the calcite and distorting the layers. What kind of rock is it?.
-
Igneous
No. Igneous rocks formed from magma or lava. This is not an igneous rock. -
Sedimentary
No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. When it was limestone it was a sedimentary rock, but not now. -
Metamorphic
Yes!. This marble been changed by heat and pressure from a different kind of rock. It is metamorphic. -
Marble is not a rock.
No. Marble is a naturally occurring solid that forms large layers in the Earth. Marble is a rock.

What do you have to do to replicate an experiment?
-
You do the same experiment several times.
No. Doing the same experiment several times is repetition, not replication. -
You do the same experiment that someone else did.
Yes. By replicating an experiment exactly, you should get the same results as the original experiment. -
You do an improved version of someone's experiment.
For replication, you do the experiment exactly as the original scientist did, without making any changes. -
You look for errors in someone's experiment.
The purpose of replication is to verify, not to look for errors.

Which position would the Moon be in when it is a full moon?
-
A
No. This would be a half moon, with the half towards the Sun in light, and the half away from the Sun dark. -
B
No. This would be a new moon. The entire lighted side of the Moon is facing away from the Earth, so the entire side of the Moon that we can see would be dark. -
C
No. This would be a half moon, with the half towards the Sun in light, and the half away from the Sun dark. -
D
Yes! The side of the Moon that is facing the Sun is also facing us. That entire side would be illuminated (unless the alignment was right for a lunar eclipse.)

A lightning bolt has a huge amount of energy. Which of these kinds of energy is NOT a major component of lightning?
-
Heat
No. A lightning bolt can heat the air to over 30,000 °C (54,000 °F) -
Electrical
No. A lightning bolt has a tremendous amount of electrical energy, often several hundred million volts, and several hundred thousand amperes. -
Sound
No. Thunder, the sound energy produced by a lightning bolt, is so loud that it can often be heard up to ten miles away. -
Chemical
Yes. While a lightning bolt can cause chemical changes, very little of the bolt's energy is converted to chemical energy.
