The arrows in the diagrams below represent light. Which diagram best shows how a glass mirror would reflect light?
What is one difference between weather and climate?
weather describes conditions near the ground, but climate does not.
Climate describes energy from the sun, but weather does not.
weather includes precipitation, but climate does not.
Climate describes long-term conditions over an entire region, but weather does not.
Which event best describes an example of evaporation?
Water flows downhill after a storm
Dark clouds form in the sky
Rain water oaks into the ground
Solar energy heats water at the ocean's surface.
What process is represented by letter B?
Evaporation, because the water vapor is in the air
Precipitation, because rain comes from clouds
Condensation, because water is changing states to form clouds
Transpiration, because water is transforming

They are the primary consumers of plants.
What does solubility refer to?
The ability of a substance to dissolve in another substance.
The temperature at which a liquid turns into a solid.
The ability of a substance to react with oxygen.
The temperature at which a solid turns into a liquid.

Two wires carrying electricity can create a spark if they come too close together. This spark can start a fire. Wires carrying electricity are usually covered with plastic to keep them from starting a fire. Why does the plastic keep the electricity from starting the fire?
Plastic is a good insulator
Plastic can melt when heated
Plastic is softer that wire
Plastic conducts electricity
A teacher dropped a bolt into a container of maple syrup and asked the students to remove it without touching the maple syrup. At first they used a strong magnet but the bolt would not move.

The bolt is magnetic and has the same density as the syrup
The bolt is nonmagnetic and more dense than the maple syrup
The bolt is nonmagnetic and less dense than the syrup
The bolt is magnetic and less dense than the maple syrup
