What is matter?
This scale runs from 0 to 14, where 0 represents the strongest acids and 14 represents the strongest bases.
What is the pH scale?
This is the push or pull on an object.
What is force?
This is the distance between each sound wave; determines how high or low a sound is.
What is frequency?
This is a special property of light that causes it to bounce off things.
What is reflection or reflective?
This is the temperature at which a solid changes into a liquid.
What is the melting point?
This is the name for protons and neutrons together.
What is the nucleus?
This is the tendency of objects at rest to remain at rest or objects in motion to remain in motion.
What is inertia?
This high-risk industry can make you rich or cost you millions if you end up drilling a dry hole.
What is oil drilling?
This describes objects which light passes straight through.
What is transparent?

What is nuclear energy?
This is a measure of disorder.
What is entropy?
This state of matter has particles that have no definite shape or volume.
What is a gas?
These are molecules which are arranged in long chains of lots and lots of repeating small molecules; can be used to make rubber or plastic products.
What are polymers?
This law of motion states that for every action, there is an equal and opposite reaction.
What is Newton’s third law of motion?
This is solid energy resource made up of dead plants that turned into carbon.

What is infrared light?
This ancient Greek scientist proved the crown maker was cheating by using water displacement to measure volume and determine the gold’s density.
Who was Archimedes?
These are electrons in the very outside energy level of an atom.
What are valence electrons?
This force acts on an object moving in a circular path and is always directed toward the center of that motion.
What is centripetal force?
This is the measurement of how loud or soft a sound is.
What is a decibel?
