Which of the following is not a characteristic of gas?

• Has a definite volume

• Fills the shape of its container

• Can be compressed

• Expands to fill its container

What is not a property of all matter?

• Mass

• Volume

• Color

• Density

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.

DOK Level 4: Extended Thinking

Investigate how changes in matter at the molecular level can lead to the development of new materials with specific properties.

• Design an experiment to create a new polymer by combining different monomers and testing the material's properties, such as strength, flexibility, and resistance to heat.

• Mix various liquids to observe color changes without considering molecular structure.

• Freeze and melt different substances to see which one lasts longer in its solid state.

• Observe the solubility of different salts in water without altering their molecular structure.

Why does an ice shelf float?

• it is more dense

• it is less dense

• the ice is melting faster than it can sink

• vegetation is sinking below and causing it to float
