Which part of your body comes closest to serving the same function as a flower?
-
Sensory organs
No. Plants can sense their surrounds just as well without flowers. -
Reproductive organs
Yes! Flowers are the reproductive organs of the plant. While most animals are either male or female, most flowers have both male (stamen) and female (pistil) reproductive organs. In this photograph, the male stamens are the green stalks with the yellow ends. The female pistil is the white structure just below the stamens. -
Digestive system
No. Plants make their own food, so they do not need a digestive system. -
Skeletal system
No. The stiff cell wall of a plant cell serves the same function as our skeleton.

This layer of rock contains fossilized tracks from a dinosaur (Dilophosaurus). The black object is my cell phone for size reference. What kind of rock is it?
-
Igneous
No. Igneous rocks formed from magma or lava. An igneous rock would not have fossilized dinosaur tracks. -
Sedimentary
Yes! Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. The presence of fossils is one of the indications that a rock is probably sedimentary. -
Metamorphic
No. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. The metamorphic process would have destroyed the tracks. -
It is not rock.
No. These dinosaur tracks are in rock.

Which of the following states of matter will change its shape to fit its container, but not its size?
-
Solid
No. Under normal pressure, solids do not change their shape or size to fit their container. -
Liquid
Yes. Liquids will take on the shape of their container, but do not change their size. -
Gas
No. Gases will expand to fill their container, taking on both its shape and size. -
Plasma

I put a paper plate on top of a glass of water. I turned it over, and the water stayed in the glass.
The weight of the water is pushing down on the paper plate, but the plate stays in the glass because the pull of gravity is being balanced by another force. What is that force?
-
Attraction
No. The slight attraction between the water and the glass is not enough to balance the pull of gravity. -
Air pressure
Yes! Because the plate is keeping outside air from entering the glass, outside air pressure is keeping the plate in place. As long as the outside air pressure is enough to balance the weight of the water and the plate, it will stay in place. If you made a small hole in the glass to let outside air get in, that would unbalance things, and the water would fall out. -
Surface tension
No. The water tension at the surface of the water would not balance the force of gravity. -
The weight of the paper card
No. Gravity is pulling down on the paper plate and the water. The weight of the paper does not help balance the force of gravity.

What is the function of the fluffy, white part of the milkweed seed?
-
It protects the seed from insects.
No. Insects could easily eat the seed, even with the fluffy top. -
It helps hide the seeds from birds.
No. The white fluff actually makes it easier for birds to find the seeds, but the moving air from their wings also helps spread the seeds. -
It gathers pollen.
No. The seed has already been pollinated before the fluff develops. -
It causes the wind to spread the seeds.
Yes! The fluffy part of the seed acts like a parachute to let the seeds blow long distances with the wind. This spreads the plant's seeds over a large area.
