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.
