100

This type of wave, like light, moves perpendicular to the direction of energy travel.

What is a transverse wave?

100

The transfer of heat through direct contact between two objects.

What is conduction?

100

Often called the "brain" of the cell, it contains the organism's genetic material.

What is the nucleus?

100

The substances you start with in a chemical reaction, located on the left side of the arrow.

What are reactants?

100

This is the energy of an object due to its motion; the faster it moves, the more of this it has.

What is kinetic energy?

200

The distance between two consecutive crests or two consecutive troughs.

What is wavelength?

200

This method of heat transfer involves the movement of currents within a fluid (liquid or gas).

What is convection?

200

The "powerhouse" of the cell where ATP (energy) is produced through respiration.

What is the mitochondria?

200

A reaction that releases energy in the form of heat or light, like a fire.

What is an exothermic reaction?

200

This specific type of potential energy is stored in objects that are stretched or compressed, like a rubber band or a clock spring.

What is elastic potential energy?

300

This phenomenon occurs when a wave bounces off a surface it cannot pass through.

What is reflection?

300

The only form of heat transfer that can travel through the vacuum of empty space.

What is radiation?

300

Found only in plant cells, these green organelles capture sunlight for photosynthesis.

What are chloroplasts?

300

This law states that matter is neither created nor destroyed during a chemical reaction.

What is the Law of Conservation of Mass?

300

At the very highest point of a roller coaster hill, the car possesses its maximum amount of this specific energy.

What is gravitational potential energy?

400

Measured in Hertz (Hz), it represents the number of wave cycles that pass a point per second.

What is frequency?

400

Materials like wood or plastic that do not allow heat to flow through them easily.

What are insulators?

400

This jelly-like substance fills the cell and holds the organelles in place.

What is cytoplasm?

400

A substance that speeds up a chemical reaction without being consumed itself.

What is a catalyst?

400

According to the Law of Conservation of Energy, energy cannot be created or destroyed, it only does this.

What is transform (or change forms)?

500

The bending of waves as they enter a new medium at an angle, caused by a change in speed.

What is refraction?

500

Warm air rising and cool air sinking creates these circular patterns in the atmosphere.

What are convection currents?

500

These small structures are responsible for protein synthesis within the cell.

What are ribosomes?

500

The minimum amount of energy required to jumpstart a chemical reaction.

What is activation energy?

500

Of the two variables in the kinetic energy formula changing this one has a greater effect on the total energy.

What is velocity?
