What force keeps objects pulled toward Earth? 

Gravity 

100

I design and improve engines, robots, manufacturing equipment, and machines. My work focuses on how things move and how forces affect them.

Mechanical Engineering

What does CPU stand for?

Central Processing Unit 

100

What type of bond forms when atoms share electrons?

covalent bonds

Which Black agricultural scientist developed hundreds of uses for peanuts and promoted crop diversification in the American South?

George Washington Carver

200

An object has a mass of 10 kg and accelerates at 3 m/s². What force is acting on it?

30 N

200

A manufacturing facility needs to reduce harmful emissions, treat contaminated water, and comply with environmental regulations. I develop solutions to address these problems.

Environmental Engineer

In programming what is a loop used to do? 

Repeat a set of instructions 

200

What happens to the pressure of a gas if its volume decreases while temperature remains constant?

Pressure increases 

200

Who was the first Black woman to travel into space?

Mae Jemison

300

If the radius of a pipe DECREASES while an incompressible fluid flows through it, what happens to the fluid's velocity?

It increases, it speeds up 

300

I design devices and technologies that interact with the human body. My work could involve artificial limbs, diagnostic equipment, implants, or other healthcare technologies.

Biomedical Engineer

300

What does RAM provide a computer with that allows it to temporarily store data being actively used?

short term/temporary memory

300

What type of electromagnetic radiation has a shorter wavelength: ultraviolet or infrared?

ultraviolet 

300

Who was the famous Black mathematician who worked at NASA and helped calculate spaceflight trajectories?

Katherine Johnson

400

If the wavelength of a wave doubles while its speed remains constant, what happens to its frequency?

It is cut in half, halved, reduced by half 

400

I work with reactors and other systems where extremely high temperatures and controlled reactions are used to produce useful energy. Safety, shielding, and controlling the reaction are major parts of my work.

Nuclear Engineer

400

A computer system divides a large problem into smaller tasks that can be processed simultaneously by multiple processing units. What computing concept is being used?
 

parallel processing 

400

What does the first law of thermodynamics state

Energy cannot be created or destroyed; it can only be transferred or converted from one form to another.

400

What famous Black scientist developed techniques that helped improve the production of blood plasma?

Charles Drew

500

Explain Isaac Newton's three laws of motion 

  • First Law — Law of Inertia
    An object at rest stays at rest, and an object in motion stays in motion unless acted on by an external force.
  • Second Law — Law of Acceleration
    The acceleration of an object depends on its mass and the net force acting on it.
    → Commonly written as F = ma.
  • Third Law — Action and Reaction
    For every action force, there is an equal and opposite reaction force.

A process requires two substances to react, but increasing the temperature improves the reaction while also creating unwanted products. I determine operating conditions that maximize the desired product without compromising safety.

Chemical Engineer

500

A computer stores frequently accessed data in a small, extremely fast memory location so the processor can retrieve it more quickly than from main memory. What is this memory called?

cache

500

What process describes a solid changing directly into a gas without becoming a liquid first?

sublimation 

500

Which Black inventor developed the traffic signal patent that improved the design of the three-position traffic light?

Garrett Morgan
