You have probably seen patterns of light like this in a pool of water. What causes it?
-
Absorption
No. If the light was being absorbed, the pattern would be dark instead of bright. -
Diffusion
No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the entire area brighter, not a specific pattern. -
Reflection
No. While the light has to reflect back to your eye for you to see it, reflection does not cause this pattern. -
Refraction
Yes! Refraction bends light. Waves and ripples on the surface of the water act just like the curved surface of a lens. This bends the light into patterns that have shapes similar to the ripples on the water's surface.

Why does this grasshopper have such small wings?
-
Because this species does not fly.
No. This species of grasshopper does fly. -
Because it has a mutation.
No. This is a normal grasshopper, not a mutant. -
Because it is a cricket, not a grasshopper.
No. This is a grasshopper. -
Because it is not an adult.
Yes! Grasshoppers have incomplete metamorphosis. The immature grasshoppers look similar to adults, but have some differences. The immature stages of the grasshopper has small wings, but the adult stage has large, functional wings.

This is the Navajo Sandstone, a huge layer of rock that forms the cliff in our back yard. The strange patterns in the sandstone tell us that at the time they were formed, this area was a desert, and the sand formed sand dunes. What kind of rock is sandstone?
-
Igneous
No. Igneous rocks are formed from molten lava or magma, not from sand. -
Sedimentary
Yes! Sedimentary rocks are made up of bits of other rocks that have been deposited by wind, water, ice, or gravity. This sand was deposited by the wind, making this a sedimentary rock. -
Metamorphic
No. Metamorphic rocks have been changed by heat and/or pressure. If this sandstone was exposed to tremendous heat and pressure, it could change into a metamorphic rock called quartzite. -
Sandstone is not a rock.
No. Sandstone is a naturally occurring solid that forms large layers in the Earth. It is a rock.

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. -
Ribosome
No. Ribosomes are parts of the cell that assemble proteins.
