PMA 3 Science Review

A student studies these two illustrations of the same area of land in the southern United States. The student concludes that a drought caused the stream to become dry. Which other explanation is MOST plausible to account for the difference between the illustrations?

• The water table beneath the stream moved to the surface.

• The stream banks became too eroded to hold water.

• The direction of water flow in the stream reversed.

• The stream changed course farther upstream.

DOK Level 3: Strategic Thinking

Design a project to compare the effects of physical changes (such as temperature and pressure) on different states of matter.

• Heat and cool water, ice, and steam to observe changes in state and record temperatures at which these changes occur.

• Freeze and melt different metals to see which one has the highest melting point.

• Apply pressure to various solids to determine their hardness.

• Observe the color changes in substances when heated without measuring temperature.
