Matter and Its Interactions
This table organizes all known elements by atomic number and properties.
What is the Periodic Table?
This law says objects stay at rest or move in a straight line unless acted on by a force.
What is Newton’s First Law (Law of Inertia)?
This is the energy of motion.
What is kinetic energy?
This is the distance from one wave crest to the next.
What is a wavelength?
A glow stick releases energy. What kind of change is happening?
What is a chemical reaction?
This type of substance is made of two or more elements chemically combined in a fixed ratio.
What is a compound?
If you push a heavy object and a light object with the same force, the lighter one moves more. This is...
What is Newton’s Second Law?
Stretching a rubber band stores this kind of energy.
What is potential energy?
Sound waves require a medium, but these types of waves do not.
What are electromagnetic waves?
This type of energy is absorbed when ammonium chloride dissolves in water and the pack gets cold.
What is thermal energy?
You add heat to a solid and it becomes a liquid. This change is called...
What is melting?
For every action, there is an equal and opposite reaction. This is known as...
What is Newton’s Third Law?
When ice melts in warm water, energy transfers in this direction.
What is from the water to the ice?
Turning up the volume increases this wave property.
What is amplitude?
This process is used to improve a design after testing it.
What is modifying or redesigning based on test results?
After mixing two clear liquids, bubbles form and the temperature rises. What likely occurred?
What is a chemical reaction?
This force exists between any two objects with mass.
What is gravity?
This law says energy cannot be created or destroyed.
What is the Law of Conservation of Energy?
This part of the electromagnetic spectrum lets us see colors.
What is visible light?
Name one example of a synthetic material and a natural resource it's made from.
What is plastic from petroleum? (or similar)
This law states that the mass of the reactants equals the mass of the products in a chemical reaction.
What is the Law of Conservation of Mass?
Increasing the number of wire coils around an iron core does what to an electromagnet?
What is it increases the strength of the magnetic field?
This kind of energy transfer is happening when a bowling ball knocks over pins.
What is kinetic energy being transferred to the pins?
This is how cell phones and Wi-Fi send information through the air.
What is electromagnetic wave transmission?
Why is it important to use models in science and engineering?
What is to represent systems, make predictions, and test designs safely?
