These building stones are made of a rock called coquina. The rock is almost entirely made up of pieces of fossil sea shells. What kind of rock is it?
-
Igneous
No. Igneous rocks formed from magma or lava. That would have melted and destroyed the fossil shells. This is not an igneous rock. -
Sedimentary
Yes! Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. These bits of shell were deposited by water, so coquina is a Sedimentary rock. -
Metamorphic
No. Coquina has not been changed by heat and pressure from a different kind of rock, so it is not metamorphic. -
Coquina is not a rock.
No. Coquina is a naturally occurring solid that forms large layers in the Earth. Coquina is a rock.

I gave this balloon a negative electrostatic charge by rubbing it on my hair. Then I tore up bits of paper, and put them on the table. When I brought the balloon near them, they were attracted to the balloon. Why?
-
The negative charge of the balloon induced a positive charge on the paper.
Yes! The negative charge on the balloon pushes some of the negatively charged electrons in the paper to the far side, leaving the near side with a positive charge. Opposite charges attract, so the paper is attracted to the balloon. -
The negative charge of the balloon attracts the neutrally charged paper.
No. As long as the paper is neutral, it will not be attracted or repelled. -
Tearing the paper gave it a positive charge.
No. If the paper had a positive charge from being torn, the bits of paper with like charges would have repelled each other before you moved the balloon nearby. -
Paper is always attracted to balloons.
No. This is easily tested by using a balloon that has not been rubbed on your hair. Without the positive charge, the paper is not attracted.

When this traffic jam starts moving, the cars will be able to speed up faster than the big trucks. Why?
-
The cars have more powerful engines.
No. The trucks have more powerful engines than the cars do. -
The cars have tires with more friction.
No. The truck tires are larger, which means they have more contact with the ground, and more friction. -
The cars weigh less.
Yes! The heavier an object is (the more mass it has), the more force it takes to move it. The trucks weigh a lot more than the cars, so it takes much more energy to get them moving. -
The cars are more streamlined
No. A streamlined shape helps when the cars are moving quickly, but does not do much as they are starting up.

The dark spot in each of these cells contains genetic material called DNA. This part of the cell is called the:
-
Vacuole
No. A vacuole is used for storing water or nutrients, not DNA. -
Nucleus
Yes! The nucleus of the cell contains DNA. -
Chloroplast
No. Chloroplasts contain chlorophyll, which is used in photosynthesis. -
