Erica is observing different substances in her science class. She notices that in one state of matter, the molecules move freely and are practically unaffected by attractive forces between them. Which state of matter is Erica observing?

• gas

• solid

• liquid

• plasma

Olivia is pouring water into a glass and notices that the surface of the water curves where it touches the sides of the glass. What is the name of this curved surface?

• meniscus

• apex

• vertex

• equator

Modified True/False: If the statement is true, write true in the blank. If it is false, replace the underlined word(s) with the word(s) that will make the statement true.

Kole notices that when he dips a paper towel into water, the water climbs up the towel. The attractive force that holds the water molecules to the paper towel is cohesion.

• adhesion

• cohesion

• diffusion

• osmosis

Modified True/False: If the statement is true, write true in the blank. If it is false, replace the underlined word(s) with the word(s) that will make the statement true.

Ezra is learning about why water pressure increases as you go deeper in a swimming pool. He reads that the two factors that affect gravitational pressure are the density and mass of the liquid.

• depth

• temperature

• volume

• surface area

Modified True/False: If the statement is true, write true in the blank. If it is false, replace the underlined word(s) with the word(s) that will make the statement true.

Abigail is using a hydraulic car jack to lift her car. The principle stating that the pressure applied to the fluid in the jack is distributed equally throughout the jack is Maxwell's principle.

• Pascal's

• Archimedes'

• Boyle's

• Bernoulli's

Modified True/False: If the statement is true, write true in the blank. If it is false, replace the underlined word(s) with the word(s) that will make the statement true.

When Grace places a thin glass tube into a cup of water, she notices that the water rises slightly inside the tube. This phenomenon is called capillarity.

• capillarity

• viscosity

• true

• surface tension

Modified True/False: If the statement is true, write true in the blank. If it is false, replace the underlined word(s) with the word(s) that will make the statement true.

Isla notices that when she heats water on the stove, the water molecules move faster. She learns that the idea that all molecules are in constant motion and move at a speed determined by temperature is the dynamic theory of matter.

• kinetic

• atomic

• potential

• mechanical
